The climate in Warsaw is humid continental, giving you bitterly cold, snowy winters and mild to hot summers. On average, summer (June to August) temperatures range between 52°F (11°C) and 76°F (24°C), while winter (December to February) temperatures range between 24°F (-4°C) and 42°F (6°C).
Although there is sporadic rainfall throughout the year, July brings the highest rainfall. Generally, rainfall peaks in summer, with winter months staying driest. Spring (March, April, May) and autumn (September, October, November) offer pleasant, mild temperatures with plenty of sunny days, although autumn mornings often turn misty.
Warsaw is most pleasant during July and August, but these warmer months also draw the largest tourist crowds. Many travellers now opt for the shoulder seasons of late spring (May) or early autumn (September) to enjoy good weather with fewer tourists and better accommodation rates.
