Traveller notes on Mundaka in June
Notes from nearby Bilbao (24 km away)
Mundaka doesn't have its own notes for June yet — these are about Bilbao, close enough to share the season.
June in Bilbao is sunny and warm and a raincoat is still advisable, which regulars explain with a local figure rather than an average: the city records rain on something like 185 days a year and has no dry month at all, though June itself takes only about five of those wet days. Our row gives 78.2mm across 10.2 precipitation days under 24.5C, and the 83 percent humidity is the Basque coast showing through. The word to know is sirimiri - a slow, fine, long-lasting drizzle rather than a downpour, the same thing San Sebastian regulars warn about - and it is why a hood beats an umbrella here. The record: 15C nights, feels-like 26C, 10.7 hours of sun, a 20.4C sea and AQI 43.
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.
