What is the best time to visit Washington DC for good weather?
Spring (late March to May) and autumn (September to November) offer the most pleasant conditions, with mild temperatures and lower humidity. April’s cherry blossoms are a major draw, but bring layers as mornings can still be cool. Summer (June to August) is hot and humid, often topping 32°C in celsius, while winter can bring icy spells and occasional snow.
What should I pack for a trip to Washington DC?
For spring and autumn, pack a mix of light layers and a waterproof jacket. Summer demands breathable fabrics, sun cream and a reusable water bottle. In winter, a warm coat, hat and gloves are essential. Comfortable walking shoes are non-negotiable year-round, as you will cover a lot of ground on the National Mall.
Is Washington DC expensive for UK travellers?
Accommodation and dining in central DC are on par with London prices, but many major museums and monuments are free, which helps balance the budget. Use the Metro to save on taxis. School holidays such as half-term and Easter see higher hotel rates, so book early for better value. A 14-day weather outlook can help you avoid last-minute wardrobe purchases.
