Clima en Mundaca en septiembre

Regulars call this a warm, not especially rainy month by local standards, with nights cool enough by evening that a light jacket comes out from around nine o'clock. Our row backs the warmth, 25.5C reading as 26C over 14.5C nights, though rain is a real presence at 93.4mm across 10.1 days - clashing winds off the Atlantic make this coast's weather genuinely hard to predict even in a normally dry month. Their honest local habit is the useful detail: people are out in rain gear regardless, and the streets stay packed whatever the sky is doing, so a shower here is rarely a reason to change plans. Inland spots like Rioja and Laguardia can run warmer and drier than the coast on the same day. The sea holds 22.2C. The record: humidity 79 percent, 9.6 hours of sun, a 16.1 kph wind and AQI 39.

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.
