Het weer in Mundaka in mei

Regulars rate June above May here and give the reason as instability rather than cold: May swings, and when it rains it can be the sirimiri - the slow, fine, long-lasting drizzle this coast is named for - or ordinary showers, or a thunderstorm, and they say plainly that it is hard to call. Our row reads 21.6C days over 11.3C nights with 74.8mm across 11.2 days, and a sea at 16.6C that matches their 16 to 18C and rules out swimming for most. They add a note on the long view: the month-long unbroken rains this region was known for no longer happen. The record: humidity 81 percent, 10.8 hours of sun inside 14.7 of daylight, and AQI 42.

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.
