Met Office forecasts for London indicate a maximum temperature of 17°C on April 15, under light rain and gusty southerly winds up to 30mph, closely mirroring trader sentiment with 42% implied probability on that outcome and significant volume on 16–18°C. This positioning follows a sharp cooldown from early April's record 26.6°C high in Kew Gardens on April 8—the warmest early April day in 80 years—driven by a transition to low-pressure systems bringing persistent cloud cover and precipitation that caps daytime heating despite milder southerly flows. Above the seasonal average of 13–14°C, these conditions reflect model consensus from the UK forecaster, though afternoon showers introduce minor uncertainty; final observations from official stations like Heathrow will resolve the market by day's end.
