How to use the Historical Weather Lookup
- Choose a place: search a city, town or postcode, type lat, lon, or press Use my location.
- Set the dates: pick a start and end date, or choose a quick range such as Last 30 days or Last calendar year.
- Press Find weather: the summary cards, chart and daily table fill in within a second or two.
- Explore: switch the chart between Temperature, Rain & snow and Wind, and hover or tap to read any day.
- Export: download all days as CSV for a spreadsheet, copy a text summary, or copy a link to share the lookup.
How to read the results
- High and low are the maximum and minimum air temperatures 2 m above ground during each local calendar day; mean is the average of all 24 hourly values, which is usually close to (high + low) ÷ 2.
- Average high / low are the averages of the daily values over your range. Warmest day and coldest night are the single highest high and lowest low, with their dates.
- Total precipitation adds up rain and melted snow. Wet days count days with at least 1 mm (0.04 in), the threshold most climate summaries use.
- Conditions are the most significant WMO weather code of each day, from clear sky through drizzle, rain, snow and thunderstorms.
Weather codes used in the table
| WMO code | Conditions | WMO code | Conditions |
|---|---|---|---|
| 0 / 1 | Clear / mainly clear | 61, 63, 65 | Light, moderate, heavy rain |
| 2 / 3 | Partly cloudy / overcast | 66, 67 | Freezing rain |
| 45, 48 | Fog, freezing (rime) fog | 71, 73, 75 | Light, moderate, heavy snow |
| 51, 53, 55 | Light, moderate, dense drizzle | 80, 81, 82 | Rain showers (slight to violent) |
| 56, 57 | Freezing drizzle | 85, 86 / 95 to 99 | Snow showers / thunderstorms |
Ideas for using past weather data
- Trip planning: look up the same month over the last few years to see typical highs, lows and rainy days for a destination.
- Gardening: check the last spring frost and first fall frost by looking for lows below 32 °F (0 °C), and count the frost days in the summary.
- Insurance and claims: confirm whether heavy rain, snow or strong gusts occurred around a specific date (and ask your national weather service for certified station records if you need them officially).
- Memories and trivia: find the weather on a birthday, wedding day or a famous historical date since 1940.
- Energy use: compare monthly average temperatures with your heating or cooling bills; download the CSV to calculate degree days in a spreadsheet.
Frequently asked questions
How far back does the historical weather go?
Daily data is available from January 1, 1940 to roughly 5 days before today, for any location on land or sea. One lookup can cover up to 5 years; for longer studies, run several lookups and combine the CSV files.
Where does the historical weather data come from?
It comes from the Open-Meteo Historical Weather API, which serves the ERA5 reanalysis produced by ECMWF for the EU Copernicus Climate Change Service, refined with higher-resolution ERA5-Land data where available. A reanalysis combines millions of past observations from stations, balloons, ships, aircraft and satellites with a weather model to rebuild a consistent hourly record for every grid point.
Why is the temperature different from my local weather station?
Reanalysis values describe an average over a grid cell roughly 9 to 25 km wide, so they are smoother than a single thermometer. Valleys, coasts, city heat islands and hilltops can differ by a few degrees, and local thunderstorm rainfall can be missed or spread out. For official records of a specific station, use your national weather service's climate data.
What do the precipitation, rain and snowfall columns mean?
Precipitation is the total water that fell, including melted snow. Rain is the liquid part. Snowfall is the depth of new snow, which is roughly 7 to 10 times the water it contains, so 1 cm of snow equivalent water corresponds to about 7 to 10 cm of snow. A wet day here is a day with at least 1 mm (0.04 in) of precipitation, a common climate threshold.
Can I find the weather on my birthday or another specific date?
Yes. Set the same date as both the start and the end, choose the place, and press Find weather. You get that day's high, low, precipitation, snowfall, wind and general conditions. Use Copy link to this lookup to share the exact result.
Is the wind speed sustained wind or gusts?
Max wind is the highest hourly mean wind speed at 10 meters above ground during the day. Gusts are the strongest short bursts, which are typically 1.3 to 1.6 times the sustained wind. Both come from the reanalysis model, so very local gusts in thunderstorms may be underestimated.
How do I convert the units?
Use the unit switch: Fahrenheit = Celsius × 9/5 + 32, 1 inch = 25.4 mm, 1 inch of snow = 2.54 cm, and 1 mph = 1.609344 km/h. The CSV export uses whichever units are selected when you download it.
