The Forecast line is the equal-weight average of enabled, available systems, not a calibrated or official forecast. Show models reveals the individual coloured forecasts and provider controls. Toggle a provider to include or exclude it throughout the page; Hide models only changes the display.

Rain, snow and frost percentages are the fraction of valid ensemble members exceeding the stated threshold. Thunder, hail and fog signals are fractions of members with matching weather codes; these are indicative model signals, not calibrated event probabilities. Missing data stays unavailable.

The past 24 hours contain recent model output, not weather-station observations. Model resolution, age, available variables and forecast horizon vary. An hourly display may contain interpolated model output. UKV is a deterministic forecast, so it contributes values but no invented probability.

Forecast responses are stored in this browser for one hour per location and model, including across reloads. Refresh reuses fresh saved data. If storage is unavailable, caching lasts for this tab only.

Scales describe the selected hour’s model average using fixed reference ranges. Temperature comfort and clothing suggestions are approximate; they are not personalised. Markers stop at the ends of a scale; the number always shows the forecast value. UV categories follow the EPA scale ↗.

Data sources

Forecast systems

Forecasts are supplied through Open-Meteo ↗. The page averages the systems you include in the chart legends. Availability varies by location, hour and weather detail.

Animated sky

Open-Meteo best-match forecast ↗ supplies a separate cloud profile, including cloud layers, humidity and winds at altitude. This is used for the sky and is not an extra system in the forecast average.

Stars come from the D3 Celestial star catalogue ↗, fetched through GitHub. Sun and moon positions are calculated in your browser. The animated sky is a procedural illustration.

Location search

Open-Meteo geocoding ↗, based on GeoNames ↗, supplies place names, coordinates and time zones. “Use my location” uses your browser’s location service.

How fresh is the data?

Forecast responses are cached in this browser for one hour. Fetch times above describe when the data was retrieved, not when a model was run. Older cached data and failed sources are labelled. Missing values are excluded from averages.
