Early June 2026 rainfall in London has already reached approximately 50 mm at key sites like Kew Gardens, matching or exceeding the long-term monthly climatological average of 45–60 mm. Unsettled conditions driven by successive low-pressure systems have delivered frequent showers and spells of rain, with Met Office guidance highlighting a changeable pattern through mid-month. Seasonal outlooks remain mixed, with some models favoring near-average totals and others indicating potential for wetter conditions amid variable steering patterns and limited high-pressure influence. Trader consensus around the 50–70 mm range reflects this balance between the strong start and the substantial uncertainty over the remaining three weeks, where additional model runs and observational updates will refine total accumulation prospects.
