Recent heavy rainfall early in June has pushed London totals near or above the long-term average of 45-60 mm by mid-month, with Kew Gardens already recording 50 mm through early June amid a changeable pattern of showers and Atlantic low-pressure systems. Trader consensus clusters tightly around 50-70 mm because remaining weeks carry substantial uncertainty from variable jet stream positioning and North Atlantic Oscillation phases, which can shift between drier high-pressure dominance and wetter unsettled flow. Official Met Office and MeteoGroup outlooks diverge on summer rainfall, while ENSO-neutral conditions limit strong teleconnections; final totals hinge on whether late-June model runs favor continued Atlantic moisture or building ridges that suppress precipitation.
