Climate averages notes

Averages are available for official Met Office stations only.

All values are given to two decimal places. For 'Days of' elements, 0.1 equates to one day every ten years, 0.5 to one day every two years, 2.5 to five days every two years, and so on.

Please note that units of measurement shown may not reflect those chosen in customise settings e.g. Temperature is given in °C.

Some stations may not have a complete set of climate variables.

More about analysis methods

This webpage provides long-term averages of key climate variables for specific locations across the UK. By searching for a location or selecting a climate station on the map, you can view climate averages for the 30-year periods 1961-1990 or 1991-2020. More detailed information on the data available at these locations is included below. The webpage also includes regional values and maps of averages.

The sample of station data are for general interest. Stations have been selected to provide good geographical coverage across all areas and variables. However, this does not represent every weather station in the Met Office’s network that has ever existed, or the current observing network.

Data are available for temperature, rainfall, sunshine, air frost, rain days >=1mm and mean windspeed. The averaging periods are 30-year standard reference periods following World Meteorological Organization (WMO) guidance.

For long-term climate series for the UK or regions, based on HadUK-Grid are available on the UK and regional series webpage.

Averages table

The averages table shows 30-year averages for the nearest or most similar available climate station to your chosen location. Tables below also show averages for districts, regions and the UK. Some stations may not have all climate variables available. District, regional and UK values are based on the HadUK-Grid dataset.

Averages graphs

The graph provides an alternative representation of the average data for your chosen location. By moving your mouse cursor over the graph you can see the average figures for your chosen climate variable for each month. The graph includes 20th and 80th percentile values, indicating the range of values over the 30 year period 1961-1990 or 1991-2020. We would expect, on average, one year in every five to be below the 20th percentile value, and one year in every five to be above the 80th percentile value.

Location comparison

The comparison graphs enable you to compare averages for two chosen locations. For example, you can see if one location is, on average, significantly warmer, drier, or sunnier than the other.

Averages maps

The maps show the spatial variation of the monthly, seasonal or annual averages for the selected climate variable across the UK. Maps are based on the HadUK-Grid dataset.

The station averages include stations which do not necessarily have complete records for the 30-year periods 1961-1990 or 1991-2020 over which the average is calculated. Some of these stations may also now be closed. Where data gaps occur, well-correlated observations from other stations are used to estimate values for the missing months within the 30-year period. This is a commonly-used and peer reviewed scientific methodology (Perry and Hollis, 2005) with similar approaches taken by meteorological organisations around the world.
