1 · What VeritaWeather is

VeritaWeather is a simple, single-page weather website. You type a place, and it shows you the weather right now, the air quality, an hour-by-hour outlook for the rest of the day, and a seven-day forecast. There is nothing to install and no account to create — just open the page and start using it.

The weather data comes from Open-Meteo, a free public weather service. VeritaWeather adds no cookies, no analytics, and no tracking. The only things it remembers about you are your temperature unit and your chosen colour theme, and those are stored privately in your own browser.

2 · Quick start

You can be looking at a forecast within seconds. There is no sign-up, no email, and no password.

1. Open the app. Go to veritaweather.com. The first time you visit — with no place chosen in the web address — it shows the weather for London as a starting example.
2. Type a place. Click the search box near the top (its placeholder reads City or ZIP (e.g. Denver, 80202, Tokyo)) and type a city name or postal code — for example Denver, 80202, or Tokyo.
3. Press Search. Click the blue Search button (or press Enter). The current conditions, air quality, hourly strip, and 7-day forecast all appear.
4. Pick your unit. The app opens in Fahrenheit; if you prefer Celsius, click the °C / °F button once to switch. Your choice is remembered for next time.
5. (Optional) Choose a look. Click 🎨 Theme and pick one of the seven colour schemes. This too is remembered.
On a phone, you can also tap 📍 Use my location to jump straight to the weather where you are standing, without typing anything.

3 · A tour of the screen

Everything lives on one scrolling page. From top to bottom you will find these areas.

The header

At the very top is the VeritaWeather title with the small tagline "fast · private · no tracking". On the right is a Radar → link that opens the separate radar map for whatever place you are currently viewing.

The search bar

A single text box — placeholder City or ZIP (e.g. Denver, 80202, Tokyo) — where you type a city or postal code, with a blue Search button beside it. Submitting the form (Enter or the button) starts the lookup.

The button row

Just under the search bar is a row of four secondary buttons, in this order:

The status line

A thin line of text below the buttons (and below the theme panel) shows short messages such as Finding "Denver"…, Loading forecast…, Link copied to clipboard ✓, or an error in red if something goes wrong. When it is empty it simply reserves a little space.

The weather cards

Below the status line, the results appear as a stack of cards and sections: Current conditions, Air quality, Next 24 hours, and the 7-day forecast. Each of these is hidden until it has data, so on first paint (before a place loads) you see only the header, search bar, buttons, and status line.

The footer

At the bottom, a small note credits Open-Meteo as the data source (as a link that opens in a new tab) and reminds you there is "no API key, no cookies, no analytics."

Accessibility

The controls carry the usual accessibility labels: the search box is labelled "City or postal code", the status line announces changes politely to screen readers, the theme button reports whether its menu is open, and the °C / °F button reports its pressed state. The page uses standard keyboard focus, so you can Tab between the search box and buttons and activate them with Enter or Space.

5 · Using your current location

The 📍 Use my location button loads the weather for wherever you are, without typing anything.

1. Click 📍 Use my location. The status line shows Requesting your location….
2. Your browser asks permission to share your location. Click Allow.
3. The forecast loads under the heading "Your location".
You only need to grant permission once per browser in most cases. If you accidentally block it, you can re-enable location access in your browser's site settings for veritaweather.com.
If you click Block, or your device cannot determine a position, the status line shows Location denied or unavailable (…) in red — the reason from your browser appears in the parentheses. Just use the search box instead. If your browser has no location feature at all, you will see Geolocation not supported in this browser.

Location lookups here are approximate on purpose (they do not force high-accuracy GPS), which is faster and gentler on battery. The request times out after about ten seconds, and a recent position may be reused for up to ten minutes.

6 · Current conditions

The first card is the big "right now" summary. It shows:

Below that are three stat tiles:

StatWhat it means
Feels likeThe "apparent" temperature, factoring in wind and humidity — how warm or cold it actually feels.
HumidityRelative humidity as a percentage.
WindWind speed, in the local units returned by the weather service (for example km/h).

Weather icons cover a full range of conditions — clear and mainly clear, partly cloudy and overcast, fog and rime fog, drizzle (including freezing drizzle), rain (including freezing rain), snow and snow grains, rain and snow showers, and thunderstorms (with or without hail). If a weather code is ever unrecognised, a "❓ Unknown" icon appears in its place.

7 · Air quality

When air-quality data is available for the location, a second card shows the US Air Quality Index (AQI). The card is titled "Air quality".

A large coloured badge shows the AQI number, with a word describing how healthy the air is and the small label "US AQI" beneath it. The colour and label follow the US EPA scale:

AQICategory
0–50Good
51–100Moderate
101–150Unhealthy (sensitive)
151–200Unhealthy
201–300Very unhealthy
301+Hazardous

Below the badge, individual pollutant tiles show the current readings for PM2.5, PM10, and Ozone (typically in µg/m³). A pollutant with no reading is simply left out.

Air quality comes from a separate service and is best-effort. If it is unavailable for a place — or has no AQI value — the whole air-quality card is hidden, and the rest of the forecast still loads normally.

8 · Next 24 hours

The "Next 24 hours" section is a horizontal strip of small tiles, one per hour. It begins at the current hour in the location's local time and runs forward for up to 24 hours.

Each tile shows:

The strip scrolls sideways. On a phone, swipe left and right; on a computer, use the horizontal scrollbar or hold Shift and turn the mouse wheel to move through the hours.

9 · 7-day forecast

The final section is a grid of seven day cards. The first is labelled Today; the rest show the weekday abbreviation (Mon, Tue, and so on).

Each day card shows:

All temperatures across the whole page — current, hourly, and daily — use whichever unit you have selected.

10 · Switching °C / °F

The °C / °F button toggles every temperature on the page between Celsius and Fahrenheit.

1. Click the °C / °F button at the right end of the button row.
2. The current conditions, hourly strip, and 7-day forecast re-display in the new unit.

The app opens in Fahrenheit by default. Once you change it, your preference is saved in your browser and used every time you return — an explicit choice always wins over the default.

Switching units re-loads the latest data for the place you are viewing, so it doubles as a quick way to refresh the current forecast. (If you have not loaded a place yet, the button just remembers your preference for the next lookup.)

11 · Themes & appearance

VeritaWeather ships with seven weather-inspired colour schemes — four light, three dark.

1. Click 🎨 Theme to open the theme panel, which appears just below the button row.
2. Click any theme card. The whole page re-colours instantly, and the panel closes.

The current theme is marked with a highlighted (accent-coloured) border. Each card shows a colour swatch with an accent dot, the theme's name, and a small badge saying whether it is a light or dark mode.

ThemeMode
Clear DayLight
Warm DayLight
Golden HourLight
OvercastLight
Clear NightDark
StormDark
AuroraDark

Until you pick a theme yourself, VeritaWeather follows your device's system setting: it opens in Clear Night if your device is in dark mode, or Clear Day if it is in light mode. Once you choose a theme, that choice is remembered and used on every visit.

The theme is applied before the page finishes drawing, so there is no bright "flash" when you open the app in a dark theme. Your device's address-bar colour also matches the theme's background.

12 · Sharing & deep links

The 🔗 Share button copies a link that opens the exact place you are viewing.

1. Load a location (by search or by "Use my location").
2. Click 🔗 Share.
3. The status line confirms Link copied to clipboard ✓. Paste it anywhere — a message, an email, a note.
If your browser blocks clipboard access, VeritaWeather instead shows the link in the status line (as Share link: …) and opens a small pop-up so you can copy it by hand.

What the link looks like

The share link carries the location as part of the web address, so anyone who opens it lands on the same forecast. The form depends on how you found the place:

How you searchedLink ends with
US ZIP code?zip=80202
City or other text (and non-US postal codes)?q=Tokyo
Your location (no text typed)?lat=…&lon=…

Opening a deep link

You can also build these links yourself, or bookmark them for one-click access to a favourite place. The app understands the following web-address parameters when it opens:

ParameterExampleEffect
?zip=?zip=80202Opens a US ZIP code; also pre-fills the search box.
?q= or ?city=?q=ParisOpens a city / text search; also pre-fills the search box.
?lat= & ?lon=?lat=51.5&lon=-0.13Opens exact coordinates, shown as "Shared location".
Bookmark a share link for the places you check most — home, work, family — and each bookmark opens straight to that forecast.

If a deep link cannot be resolved (for example a mistyped ZIP or city), the app shows a brief error — Couldn't open "…": … — and then falls back to the default London forecast so you are never left with a blank page.

13 · Radar

The Radar → link in the top-right corner of the header opens VeritaWeather's separate radar map at radar.veritaweather.com.

The link keeps itself pointed at whatever location you are currently viewing: once a place loads, the same location parameters (ZIP, city text, or coordinates) are appended to the radar address, so it opens the map centred on the same spot. Load a place first, then click Radar → to see it on the map.

14 · Saving, offline & installing

VeritaWeather is a live weather app: it fetches fresh data from the internet each time you load a place, so an internet connection is required to see the forecast.

What is saved

Two small preferences are stored privately in your browser:

These stay on your device and are re-applied automatically each visit. There is no account, so there is nothing to back up or restore in the cloud.

Keeping favourite places

Because VeritaWeather has no built-in favourites list, the best way to "save" a location is to bookmark its share link (see the Sharing & deep links section). A bookmark to veritaweather.com/?q=Tokyo, for example, reopens Tokyo instantly.

Adding it to your home screen

On a phone or tablet you can add VeritaWeather to your home screen so it opens like an app:

iPhone / iPad (Safari): tap the Share icon, then "Add to Home Screen".
Android (Chrome): tap the ⋮ menu, then "Add to Home screen" or "Install app".
Adding to the home screen makes launching faster, but it does not make VeritaWeather work offline — the forecast still needs a live connection to load.

15 · Privacy & your data

Privacy is central to VeritaWeather. It has no accounts, no cookies, no analytics, and no tracking.

To clear your saved unit and theme, clear this site's data in your browser's settings — VeritaWeather will simply return to its defaults on the next visit.

16 · Troubleshooting & FAQ

Common issues

ProblemWhat to do
"No match for …" when searchingCheck the spelling. For a city, add the region or country (e.g. Springfield, Illinois).
"No match for postal code …"Check the digits. For a non-US postal code, add the two-letter country code (e.g. 75008, fr). US ZIPs need no suffix.
"Location denied or unavailable (…)"You declined the location prompt or the browser could not find a position. Allow location access in your browser's site settings, or just use the search box.
"Geolocation not supported in this browser"Your browser has no location feature. Use the search box to type a place instead.
"Could not load weather: …"Usually a temporary network hiccup or the weather service being briefly unavailable. Wait a moment and search again.
"Couldn't open …" then London appearsA deep link (from a bookmark or shared URL) could not be resolved, so the app fell back to London. Re-check the ZIP or city in the link.
The air-quality card is missingAir-quality data is not available for every location. This is normal; the rest of the forecast still works.
Temperatures look wrongCheck the °C / °F button — you may be viewing the other unit. Click it to switch.
Share said the link was not copiedYour browser blocked clipboard access. Copy the link from the pop-up or the status line manually.

Frequently asked questions

Do I need an account?

No. VeritaWeather has no sign-up and no login. Just open the page.

Is it free?

Yes. It uses the free Open-Meteo weather service and requires no API key from you.

Why does it show London the first time?

London is the default example location when you arrive with no place chosen (and the fallback if a deep link can't be resolved). Search for your own city and, once you pick a unit or theme, your preferences are remembered afterwards.

How accurate is "Feels like"?

It is the apparent temperature from the weather service, which accounts for wind and humidity — a better guide to how the air will feel than the plain temperature.

Can I see more than seven days?

No. The forecast covers the current day plus the next six.

Does it work on my phone?

Yes. The layout adapts to phones, tablets, and computers, and you can add it to your home screen for quick access.

Where does the data come from?

All weather and air-quality data comes from Open-Meteo. Postal-code lookups use a keyless public service. VeritaWeather itself stores nothing about you beyond your unit and theme.
