Recent wet conditions have positioned London near or slightly above its typical June rainfall total of roughly 45-60 mm by mid-month, with Kew Gardens already recording over 50 mm by early June amid a changeable pattern of Atlantic low-pressure systems and showers. Trader sentiment clusters tightly around 50-80 mm because model guidance shows competing influences: a building high-pressure ridge could suppress further rain in the latter half of the month, while lingering instability and possible frontal passages support additional accumulation. Ensemble forecasts diverge on exact totals depending on the strength and persistence of this ridge versus residual moisture from the jet stream, keeping the 50-60 mm, 60-70 mm, and 70-80 mm bins closely matched as traders weigh the balance between recent observed rainfall and the outlook for drier, more settled weather.
