*Data from before 2009 are mostly from the historical site at Whitestone Pond in Hampstead. Where data from that record is missing, other nearby sites were used, including St James Park, Heathrow, and Kew Gardens (pre-1910). Best efforts have been made to adjust for site differences, but uncertainties are somewhat greater for this data. I am grateful to the Met Office for making this data available for free through the MIDAS Open database.
Sunshine hours are counted for each calendar day (midnight to midnight, local time) from daylight webcam imagery, as a fraction of the maximum possible.
Notes
- Sunshine hours are computed live from webcam imagery using an image classification model. Today's value is updated throughout the day as data arrives.
- Sunshine records at NW3 began in 2009. A long-term series from nearby sites is available from 1910 (use Start year above).
- Figures in brackets refer to departure from average conditions (as a percentage for sunshine)
- Sun days are days with more than 0 hours of sunshine recorded
- % of max is sunshine hours as a percentage of the maximum possible for that period.
