Despite London experiencing normal autumn rainfall levels in 2025, meteorologists are predicting an unusual pattern of continuous precipitation for the coming months. Data from NW3 London shows that autumn rainfall measured 184.7mm, reaching 101% of normal levels. This comes after a surprising November that became the wettest month of 2025 for the UK, with rainfall totaling 162.1mm nationwide, 31% above average. Temperatures across England were notably higher, marking the tenth warmest November on record with both maximum and minimum readings well above average.
London faces unusual continuous rainfall forecast despite autumn’s normal precipitation levels reaching 101% of average.
The capital saw a steady increase in precipitation throughout autumn, with monthly totals of 35.1mm in September, 52.7mm in October, and continuing into November. This pattern represents a notable shift from the drier conditions experienced earlier in the year, particularly in March when the UK recorded just 36.9mm of rainfall, far below the 1991-2020 average of 91.0mm.
Weather patterns across England have shown considerable regional variation. Northern England experienced 71% above average November rainfall, making it the fifth wettest since 1836. Meanwhile, Southern England recorded 36% above average, and East Anglia saw 148% of its normal precipitation with 92.9mm falling in November alone. These variations mirror the June rainfall patterns where the Kent catchment recorded 235% of LTA while other areas received significantly less precipitation.
The dramatic shift from dry to wet conditions is highlighted by comparing the number of rain days. March 2025 had just 3.4 rain days in England, the lowest since May 2020 when only 2.3 days with more than 1mm of rainfall were recorded. The reliability of these measurements is affected by data quality concerns from amateur-run weather stations that require additional verification. This contrasts sharply with March 2023, which had 20.4 rain days, the highest in the period 2015-2025.
Storm Claudia contributed notably to November’s heavy rainfall across England and Wales, causing localized flooding in multiple regions. The Midlands, Lincolnshire, and Yorkshire were particularly affected, receiving more than double their average November rainfall.
Looking forward, forecasters note that the predicted continuous rainfall for London follows a pattern of weather extremes. The contrast between the dry spring-summer and wet autumn suggests changing climate patterns that may lead to more unpredictable precipitation in the coming year, potentially challenging the region’s infrastructure and water management systems.
