Persistent high pressure dominating southeast England has delivered exceptionally dry conditions in London through mid-April 2026, with official monitoring stations recording just 3 mm of precipitation by April 14—only 7% of the 42 mm climatological average for the month. This follows a wet winter but aligns with Met Office summaries noting below-average rainfall in central and southern England for early April (1-2 mm for week 1-7, 3-4% of long-term average). Record highs near 26°C on April 8 further indicate settled anticyclonic weather suppressing showers. Forecast model consensus from the Met Office points to low precipitation risk for the remaining fortnight, though isolated Atlantic fronts could introduce minor variability. Trader sentiment, pricing <20 mm at 63% implied probability, reflects this observational data and outlook, against historical April norms around 42-47 mm. Weekly updates from monitoring agencies will refine end-month trajectories.
