Mundaka weather in August

Regulars call this normally the driest month of the year here on paper, warm and agreeable in the mid-to-late 20s Celsius, while being honest that the Atlantic coast setting means rain can still arrive any time regardless of the seasonal odds. Our row backs that warm, genuinely humid read, 27.4C reading as a hot 29C, over 16.9C nights, with 54mm of rain across 7.5 days and humidity at 80 percent. Regulars are consistent that a rain layer belongs in the bag even on what looks like a reliably warm week, since the region's unpredictability doesn't fully disappear even in its best month. The sea sits at a swimmable 22.9C, a real highlight for anyone splitting time with San Sebastian's beaches. The record: 11.1 hours of sun, a 15.8 kph wind and AQI 41.

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.
