Liep?ja is located in a zone with a temperate marine climate. The major factor influencing the weather in the region is the Baltic Sea, providing a mild winter and a cool summer. During the winter the sea around Liep?ja is virtually ice-free. Although occasionally some land-fast ice may develop, it seldom reaches a hundred meters from the shore and does not last long before melting. The sea warms up fully only in the beginning of August, so the best bathing season in Liep?ja is from August to September. Regular meteorological observations in the city have been conducted from 1857.
