Running in London: A Seasonal Guide

London's oceanic climate shapes the running experience across all four seasons. The mild climate makes year-round running possible, though each season has its own character.

Peak season (May and June): Expect the best combination of temperature, daylight, and dry conditions. These months reward runners who plan their weekly mileage around the weather.

Off-season strategy: Even the off-season stays runnable. Watch for rain windows rather than temperature extremes. Short weather breaks often open up ideal conditions.
