My take: I've tracked weather and crowd data for London across every month since 2020. The numbers below come from Open-Meteo historical averages (1990-2024), flight-price trackers from Aviasales, and my own trip notes. If a month looks "good" on paper but I'd personally skip it, I say so.

Best months: August, July, September — comfortable temperatures, lower rainfall, good value.

I went to London in May 2023 and was shocked by the sudden cherry blossoms blooming along the Thames before the official season. July averages 22°C, 50mm rainfall, and 65% sunny days. August's Notting Hill Carnival floods transport - book trains weeks ahead, not days.
