Utrecht features a temperate maritime climate (Köppen climate classification *Cfb*), heavily influenced by the North Sea and the Atlantic Ocean. This results in relatively mild winters and comfortably warm, though rarely extreme, summers.
Average daytime temperatures in the winter (December to February) hover around 3°C to 6°C (37°F to 43°F), with snowfall being infrequent and rarely accumulating for long. Summers (June to August) are pleasant, with average highs ranging from 20°C to 24°C (68°F to 75°F). Rainfall is fairly evenly distributed throughout the year, with an annual average of about 800 mm. The best time to visit is from May to September, when the weather is warmest and the province's extensive outdoor cafe culture, boating, and cycling paths can be fully enjoyed.
