UK temperature anomalies are plotted by default with respect to 1991-2020 daily climate, calculated for each individual UK site using official observation data. You can select a 30 year climate base period of your choice between 1951-1980 and 1991-2020 by selecting the appropriate radio button in the display. The daily climate is calculated by taking a 15-day rolling mean centred on the day in question, and can be visualised (with further info) here: Daily Climate.

Temperature percentiles are calculated using a 15-day climate centred on the relevant date, the climate itself using all available observations within that time window. Currently only available for UK sites.

Temperature anomalies for the Republic of Ireland are currently calculated using interpolated monthly means for the period 1981-2010, so in order to be consistent when comparing UK and ROI anomalies, select 81-10 as the climate using the radio buttons in the display window.
