Latest Met Office and BBC Weather forecasts, updated April 16, project London's highest temperature on April 17 at 18°C under sunny intervals and light southwesterly winds (12-25 mph gusts), aligning trader sentiment with 18°C (44.5% implied probability) leading over 17°C (33.5%). This follows today's showery conditions capping highs at 16°C, as mild Atlantic air advection replaces unsettled weather, with low midday precipitation risk (under 30%) enabling solar heating above the April climatological average of 14°C. Model consensus shows minor spread from variable cloud cover and potential afternoon rain encroachment from the west, which could cap peaks; official Heathrow measurements will resolve the market by day's end.
