Climate & Weather in Riga

Good to Know

• Summer (June–August) is genuinely the best window for visiting—mild temperatures, extended daylight, and reasonable rainfall. Pack layers, as nights remain cool.
• Winter (December–February) means significant snowfall with 70–84 cm/month and temperatures dropping to –5°C (41°F). Days are extremely short (6–7 hours in December); consider extra lighting and mood-support if sensitive to limited daylight.
• Spring (March–May) and autumn (September–November) are transitional seasons with increasing rain and rapidly shifting temperatures. Prepare waterproof gear.
• The Baltic Sea remains cold year-round; water temperature peaks at 18.5°C (65°F) in August, making swimming possible but not comfortable. February and March are the coldest months at ~1°C (34°F).
• Rain is frequent and well-distributed throughout the year. July sees the highest rainfall (~79 mm) due to afternoon thunderstorms. Even drier months (March, ~34 mm) still see regular precipitation.
• Riga's coastal location moderates winter slightly compared to inland Latvia, but snow and cold remain dominant December–February.
