Forecast

Rennes has a temperate maritime climate. Ocean and Atlantic winds bring low air pressure, making it quite changeable. Weather patterns from the Atlantic often bring low-pressure systems. Rennes's location near the ocean and in a valley affects air pressure. The surrounding hills can trap air, making pressure higher in summer and lower in winter. In winter, low pressure brings rain and strong winds. In summer, high pressure makes it warm and sunny. The climate type means air pressure changes are moderate, not extreme. Spring and autumn have more changeable pressure, with sunny and rainy days. The Bay of Brest's influence helps regulate Rennes's air pressure. Low-pressure systems move in quickly, bringing rain. Winds from the Atlantic keep Rennes's air pressure relatively stable.
