The best time to visit Twickenham really depends on what you're hoping to experience, but generally, late spring (May to June) and early autumn (September to October) offer pleasant weather and a good balance of activities.If you're coming for rugby, the autumn internationals (November) and the Six Nations Championship (February/March) are key times. While the weather might be a bit cooler and wetter, the atmosphere around Twickenham Stadium and the local pubs is unmatched. You'll want to book accommodation well in advance for these periods.For those looking to enjoy the area's parks, gardens, and riverside walks, May, June, September, and early October are ideal. The weather is typically milder, superb for exploring places like Richmond Park or Kew Gardens, and the leaves changing colour in autumn are particularly lovely.
