Off-season — lowest travel prices with still acceptable climate.
March in Brittany is on the cool side — with highs around 12°C (54°F) it's less suited for a beach holiday, but good for sightseeing away from the high season.
Temperatures reach a maximum of 12°C (54°F) during the day and drop to 5°C (41°F) at night — warm layers recommended. Peaks reach around 19°C (66°F), the coldest nights around -1°C (30°F) — frost does occur. With 5 sunshine hours per day and 7 rain days (42 mm (1.7 in)), this is one of the cloudier months. At 10°C (50°F), the water is still quite cool in March — a wetsuit may be useful.
Pack warm clothing and sturdy footwear. Cool temperatures make hiking and cultural trips enjoyable — beaches are off the agenda.
The days lengthen, gorse blooms yellow on the cliffs and in April the sun shines a good seven hours a day. The coastal paths, along the Côte de Granit Rose for example, are almost deserted. The sea stays cool and the weather changeable.
