WeatherThere is no season when the weather is predictably wonderful. In May and October, day temperatures can be cool, but they have occasionally been known to be very warm; June-September it's more reliably warm, although June can often be rainy. Average temperatures run 43 F/6 C in January, 72 F/22 C in July. Summer heat waves have become common, and August can be very hot and humid. Though it rains more in other parts of the country, London typically gets some rainfall half the days of the year—especially in winter. Take along an umbrella and sweater no matter when you go.
