Meteo Mundaka in gennaio

Forum posters put January at roughly half rain, half sun rather than a washout - Bilbao and the Bay of Biscay coast are simply wetter than Mediterranean Spain, and visitors shouldn't expect continuous rain so much as a real chance of it most days. The recurring advice: bring an umbrella wherever you go regardless of forecast, and keep a museum or two in reserve for the wetter stretches. Temperatures themselves aren't singled out as a complaint - the rain, not the cold, is what regulars warn newcomers about.

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.
