Trader consensus overwhelmingly favors a highest temperature of 15°C in London on March 17, driven by the latest ensemble forecasts from the UK Met Office and ECMWF models, which converge on mild, settled conditions under a weak high-pressure ridge with maximums peaking at 14-15°C amid light southerly winds. Historical March data from Heathrow observations shows average highs near 11°C, but current sea surface temperatures and stratospheric warming patterns support this slightly above-normal outlook, with 95th percentile model runs capping below 16°C. A realistic challenge would require an unanticipated warm advection from the Continent or stalled frontal boundary, though probabilities remain under 1% per official guidance.
