Climate Characteristics of Poland

1. General Climate

• Coastal areas: Along the Baltic Sea coast, including cities such as Gdańsk, the climate is maritime. Winter temperatures are low but generally less severe than in inland regions. Summers are mild and relatively humid, which can lead to cloudy weather and frequent rainfall.
• Lowland areas: In central parts of Poland, including Warsaw, the climate is more continental. Winters are cold and snowy, while summers can be warm, with relatively high temperatures. The influence of the Baltic Sea is much weaker in these inland areas.
• Mountain areas: In southern Poland, particularly in the Tatra Mountains, the climate is mountainous. Winters are very cold and snowy, with temperatures significantly lower than in the lowlands. During summer, temperatures generally remain relatively mild.

2. Seasons

Winter (December–February)

• Temperature: Temperatures are generally very low, ranging from approximately -10°C to 0°C. In mountainous areas, temperatures can fall below -20°C. Snow is common, especially in southern Poland and mountainous regions.
• Humidity: Humidity is relatively high in coastal areas and the northern lowlands, contributing to damp and wet weather conditions. Inland areas tend to be somewhat less humid, although humidity can still be relatively high.

Spring (March–May)

• Temperature: Temperatures gradually increase throughout the season, with warmer days becoming more common toward the end of spring. Temperatures generally range from 5°C to 15°C in early spring and rise to around 15°C–20°C by late spring.
• Humidity: Humidity is generally moderate, with more sunny days and cool nights. The transition from winter to spring usually brings gradually improving weather conditions.

Summer (June–August)

• Temperature: Summers are relatively warm, particularly in eastern Poland, with temperatures commonly ranging from 20°C to 30°C. Temperatures in western Poland may occasionally be slightly lower.
• Humidity: Humidity can be relatively high, especially in coastal areas and regions close to the Baltic Sea. Rain and thunderstorms may occur periodically throughout the summer.

Autumn (September–November)

• Temperature: Temperatures gradually decrease, generally ranging from 10°C to 20°C during the earlier part of the season. In late autumn, temperatures can fall below 10°C.
• Humidity: Humidity increases as the season progresses, accompanied by more frequent rainfall. Days become shorter, and the weather becomes increasingly cool and damp, particularly in late autumn.

Overall, Poland's climate varies considerably depending on geographical location and elevation. The influence of the Baltic Sea is most noticeable in coastal and northern regions.
