Trader sentiment clusters tightly around 13°C and 14°C for London's highest temperature on March 23, driven by the latest ECMWF and UK Met Office ensemble forecasts showing model runs clustered at 12-15°C amid a mild Atlantic high-pressure ridge. Historical March highs average 11-12°C at Heathrow, but southerly winds and above-normal geopotential heights signal a 2-3°C boost, differentiating outcomes: persistent low cloud favors 13°C stagnation, while afternoon clearing or urban heat island amplification in central London could nudge to 14°C or 15°C. Traders eye hourly updates from official stations like Heathrow, as small variances in insolation resolve the razor-thin market-implied odds.
