Traveller notes on Mundaka in March

Notes from nearby San Sebastián (59 km away)

Mundaka doesn't have its own notes for March yet — these are about San Sebastián, close enough to share the season.

Forum posters call March better than January/February but still genuinely rain-prone, with temperatures generally 10-15C - not beach weather by any measure. Carnival wraps up in February and Holy Week doesn't start until April, so March itself is a quiet stretch with no major events, meaning deserted restaurants and bars outside weekends. Unlike many Spanish coastal towns, San Sebastian has no real off-season closures - everything stays open year-round regardless of the quieter foot traffic. The overall read: reasonable to visit if occasional rain and mild-not-warm temperatures don't bother you, though summer remains the clear favorite among regulars.

Other months in Mundaka

Mundaka-forum reviews describe October as the real start of the Basque coast's main surf season: the legendary left-hand rivermouth wave begins waking up as autumn swells arrive, water still holds late-summer warmth even as air temperatures cool, and the point stays workable across a wide four-to-eight-foot range with fewer crowds than the peak November-December months. Weather-wise, visitor accounts are candid that this quaint fishing town's charm doesn't always come with good weather - one reviewer flatly says the weather was poor during their stay, rain included, while still calling the visit worthwhile for the views and the town itself. The general pattern regulars describe is a genuinely wet autumn, showers arriving without much warning even between swell-watching sessions. The record: 21C days, 13.8C nights, a notably high 134mm across 14 days, a 20.4C sea, 74 percent humidity and just 7.5 hours of sun - a wet, cloudy month that matches the mixed-weather reviews closely.
