October in London: climate and what to expect

Mid-October mornings in London arrive damp and grey, with temperatures hovering around 15.5°C (60°F) at their peak and dropping to 8.9°C (48°F) by evening. You'll see roughly 76mm of rain spread across about 12 days, often arriving as drizzle rather than downpours. Sunshine clocks in at just 6.2 hours daily—enough for late-afternoon walks through parks, but don't bank on clear skies. The Thames embankment feels particularly atmospheric on these shorter days, and locals shift into layering mode.

The city's energy in October is distinctly autumnal. Summer tourists have thinned out, so museums and galleries feel less crowded, though weekends still draw families enjoying half-term holidays. The Frieze Art Fair brings collectors and art enthusiasts in early October, and Halloween decorations gradually appear in shop windows. Restaurants and pubs feel cosy rather than packed, and accommodation prices drop noticeably compared to September—a genuine sweet spot for budget-conscious travellers who don't mind the chill.

Over the past decade, October temperatures have remained remarkably stable around this 15–16°C range, though rainfall patterns have become slightly more variable. 2026 is tracking close to the historical norm, with no major climate shifts expected. Early October tends slightly warmer and drier than late October, so timing within the month matters if you're weather-sensitive.

This month suits photographers drawn to golden light and bare branches, walkers comfortable in cool air, and anyone seeking London without the summer crush. Plan indoor backups—galleries, the British Museum, West End theatre—for rainy afternoons. Pack layers you can shed indoors; you'll move between heated tubes, chilly streets, and warm cafés throughout each day. 2026 visitors should book accommodation early if targeting weekends, but weekday rates remain reasonable.
