How often does it rain in Brighton?
Brighton records around 920mm of rain a year, spread across about 147 days — roughly 40% of all days, or 12 days in an average month. In practice that makes rain a regular feature of running in Brighton rather than an exception — close to one day in two. A decent waterproof and a peaked cap earn their place in the kit bag year-round.
The wettest month is October, averaging 109mm across about 14 rainy days. The driest is April, with 48mm over roughly 10 days. Average lows bottom out around 3.3°C in January — long-sleeve and light-glove weather rather than full winter kit. Summer highs peak around 20.5°C in August, comfortable for most daytime running.
Those are ten-year averages, not a forecast. What actually matters on the day is the next twelve hours — which is what the live verdict and hourly strip at the top of this page are for.
