London in August

May through September offers the best weather odds, but London's charm doesn't depend on sunshine. Summer brings festival season—from Wimbledon in June to the Proms in July and August. Hyde Park fills with outdoor concerts, and every pub spills onto the sidewalks during those rare 25°C days. April and May see fewer crowds and blooming parks, especially in Regent's Park where the roses put on a show. October delivers autumn colors in Hampstead Heath and Richmond Park, plus the London Film Festival brings star sightings to Leicester Square. Winter means Christmas markets, ice skating at Somerset House, and theater season in full swing. The days are short but the city glows under streetlights. Just pack layers—London weather changes faster than the Queen's Guard rotation. Rain gear isn't optional; it's survival equipment.
