DETAILED OUTLOOK
Forecast loadingEvery hour, at a glance
Search above to load hourly conditions.
Hourly forecasts are model estimates, not guarantees. Precipitation probability describes the chance of precipitation during the forecast period; it does not mean it will rain continuously for the whole hour.
Temperature vs. feels like
Apparent temperature estimates how conditions may feel after factors such as wind and humidity are considered. Use it alongside the actual temperature when choosing clothing or planning exercise.
Watch gusts and changing wind
Wind can affect cycling, boating, exposed areas and outdoor events. Gusts can be stronger than the average wind shown in a general forecast, so follow local advisories when conditions are hazardous.
HOURLY FORECAST FAQ
What you should know
How often does this hourly forecast update?
The page requests forecast data from Open-Meteo through the Weather Penguin server endpoint. Results may be cached briefly and update when refreshed; availability and update frequency depend on the provider’s model runs.
Why can the forecast change?
Forecasts use weather models and new observations. As the atmosphere evolves and models update, the expected timing of rain, wind or temperature changes can shift.
How far ahead should I trust the hourly forecast?
The next several hours are often more useful for precise timing than the later part of a multi-day outlook, but uncertainty exists at every range. Check again before important plans and use official warnings for safety decisions.
Where does the data come from?
Weather Penguin retrieves forecast variables from the Open-Meteo Forecast API. The API provides hourly temperature, relative humidity, precipitation probability, weather codes and wind speed. Read the Open-Meteo documentation ↗
