What is the best time to visit Westminster?
Late spring (May to June) and early autumn (September to October) offer the most comfortable conditions: moderate temperatures, longer daylight, and lower rainfall than mid-winter. July and August are warmest but also busiest with school holidays and tourists. For quieter visits, aim for weekdays in May or September.
What should I pack for Westminster weather?
A layered approach works best. In winter (December–February) bring a warm coat, scarf and gloves; temperatures rarely drop below freezing but damp chill is common. Summer (June–August) calls for light clothing plus a rain jacket or umbrella – sudden showers happen. Comfortable waterproof footwear is useful year-round, especially if you plan to walk along the Thames.
