UK Temperature & Rainfall
Monthly patterns and long-term climate trends
Key Findings
The UK experiences mild winters (4-7°C) and cool summers (15-20°C), with rainfall distributed relatively evenly year-round.
Trends
Average temperatures are increasing, rainfall patterns are becoming more erratic, and extreme weather events are more frequent.
Relevance
Essential for understanding climate change impacts, agricultural planning, and assessing flood risks across different regions.
Data Overview
The UK has a temperate maritime climate, heavily influenced by the Atlantic Ocean and the Gulf Stream. This means it generally lacks extreme temperatures, with an average annual temperature of around 9°C and average annual rainfall of approximately 1,000mm.
However, there are distinct regional variations. The west and north (e.g., Wales, Scotland) are generally wetter and windier due to prevailing south-westerly winds bringing moisture from the Atlantic. The east and south (e.g., East Anglia, London) are drier and warmer, benefiting from a rain shadow effect caused by western hills and mountains.
Average UK Monthly Climate Data
Climate Trends & Seasonal Analysis
Recent decades have shown a clear warming trend, with the UK's ten warmest years on record all occurring since 2002. Winters are becoming milder and wetter, while summers are becoming hotter and drier, increasing the risk of both winter flooding and summer droughts. These shifts have profound implications for UK agriculture, water resource management, and infrastructure resilience.
