Wet Hours: monthly totals for all months since 2009 in London, NW3. Data for Wet Hours begins in 2009.

Figures in brackets refer to departure from recent average conditions (the anomaly for the current month is unadjusted for the month's degree of completeness).

Hours with measurable rainfall during the day (midnight to midnight, local time). Estimated heuristically from rain observations.
