Heathrow Airport will typically see summer highs of 22-24°C and winter peaks of just 6-8°C, according to new 30-year climate averages released by the Met Office for Greater London.
The comprehensive data provides a statistical baseline for the UK's busiest airport, covering everything from rainfall patterns to wind speeds that directly impact flight operations and infrastructure planning. For the millions of passengers passing through Heathrow annually, the figures offer insight into what weather conditions to expect throughout the year.
The long-term averages show rainfall distributed fairly evenly across all months, though autumn typically brings slightly wetter conditions. No single month experiences exceptionally high or low precipitation, reflecting the temperate climate characteristic of south-east England.
Wind speeds vary considerably by season, with stronger conditions more common during autumn and winter months. These patterns prove crucial for aviation safety and operational planning at one of the world's major transport hubs.
The data places Heathrow's climate in line with broader south-east England trends - generally warmer temperatures and lower rainfall compared to Scotland or Wales. This regional variation helps climate scientists and urban planners develop targeted strategies for different parts of the UK.
Beyond aviation, the figures have practical implications for Greater London residents and businesses. Homeowners can better assess heating and cooling needs, while water management strategies benefit from understanding typical rainfall patterns. Gardeners and agricultural planners also rely on such long-term climate data for seasonal planning.
The Met Office compiles these 30-year averages using decades of collected data, ensuring robust and reliable climate representations that form the foundation for assessing current weather phenomena and climate change impacts.
