London weather in April 2026

April mornings in London feel damp and cool—you'll wake to around 5°C (41°F) and need a layer, but by midday temperatures climb to 14°C (57°F), enough to shed a jacket if you're walking. Expect roughly 36mm of rainfall scattered across about 9 days, which means most days stay dry but you'll catch showers without warning. Sunshine stretches to nearly 10 hours daily, giving photographers and park-walkers genuine golden light in the late afternoons, though evenings still bite at that 5°C mark.

London's parks explode in April—cherry blossoms line the Thames, and locals reclaim outdoor cafés in Soho and around Borough Market. The Easter holidays stagger crowds depending on timing, but generally the city feels busier than March yet quieter than May. Prices tick upward from winter lows but haven't hit summer peaks; hotels and restaurants sense the season turning. You'll see families on school holidays, couples testing spring romance, and street musicians returning to their regular corners.

Over the past decade, April in London has stayed remarkably consistent, hovering around 14–15°C for highs. 2026 tracks with historical patterns—no major warming trend yet, though the occasional mild year pushes closer to 16°C. Rainfall has been stable too; April's 36mm is reliable, so pack rain gear without overthinking it.

April suits travelers who enjoy layering, don't mind a light rain jacket, and want London without the summer tourist surge. Photographers gain from long daylight and soft spring light. Families appreciate school holidays and kid-friendly outdoor attractions. Budget travelers benefit from mid-season pricing. Plan around variable mornings and pack a waterproof layer; you'll thank yourself by 3pm when the sun breaks through.
