Weather you can verify.

WeatherVerity presents weather model output supplied by Open-Meteo. Place names and coordinates come from GeoNames, through Open-Meteo geocoding. Values are formatted and rounded for readability; we do not invent replacements for missing data.

What “current” means

Current conditions are estimates from weather models, not verified readings from a station at your exact address. We show the time the estimate is valid for separately from the time we retrieved it. The precipitation field covers the current interval shown beside it.

Reading the seven-day forecast

Each row covers a local calendar day. Temperatures are in Celsius, precipitation amounts in millimetres and wind speeds in metres per second. “Rain chance” shows the maximum precipitation probability for that day; precipitation may include snow and other forms, not just rain. It is not a percentage of the day that will be wet. Wind is the daily maximum at 10 metres above ground.

Times, sources and freshness

Times on place pages use that place’s named time zone. Current data is cached for up to five minutes, hourly forecasts for up to fifteen minutes, daily forecasts for up to thirty minutes, and rendered pages for up to one additional minute. A page kept open does not update itself; reload it for a newer response. Source retrieval timestamps remain unchanged while a response is cached. If an update fails, the shared cache can show an explicitly labelled older forecast for up to ten additional minutes for current conditions, thirty for hourly data and sixty for daily data. Current estimates stop being served at one hour past their valid time; hourly and daily fallbacks stop at a local date change. Fallback reads never extend these limits.

The selected API does not provide a model-run issue time with these responses. We label that as unavailable. The field generationtime_ms is the API’s processing duration, not the time a forecast was issued.

Backup weather

When configured, MET Norway is a secondary source if Open-Meteo cannot supply validated data. The affected sections identify the provider. MET wind is a 10-minute mean, and its time points do not necessarily supply equivalent daily extrema, probabilities or condition codes. A backup daily table therefore labels sampled ranges explicitly and leaves unsupported fields missing. This is failover, not a verified multi-model consensus.

What this release can compare

Open-Meteo is the primary provider and selects suitable weather models. A configured backup replaces unavailable sections; it does not combine providers into an independent comparison or consensus forecast. See the Open-Meteo documentation for model selection and variable definitions.

Your location on the homepage

The location card appears as soon as the page opens. On the live site we can use an approximate city from your internet connection. This can be inaccurate with VPNs or mobile networks; change the place whenever needed. Choosing “Set as my location” remembers only that public place ID in this browser until you clear site data. We do not request GPS access. Local previews require a place selection. Personal location responses are not stored in shared page caches.

Attribution and use

Weather data: Open-Meteo. Place data: GeoNames. Attribution licence: CC BY 4.0. Presentation changes include unit selection, rounding and condition labels.

When data is unavailable

Missing individual values are marked “Not provided”. If a service is unavailable or its response cannot be validated, that section displays an error. WeatherVerity does not provide an official severe-weather warning service; consult your local meteorological authority for alerts.
