*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.

All-time wind rose for NW3 (2009-present)
Wind speed, gust and direction extremes for each calendar day run midnight to midnight (local time), when daily extremes are reset.
Notes
- Valid station wind records began in August 2009. Mean speed from nearby sites is available from 1949 (use Start year above).
- Figures in brackets refer to departure from average conditions
- "Speed" is the windspeed sampled over a one minute period; "Gust" is the windspeed sampled over a 14 second period.
