Mundaka weather in April

Regulars cite the old Spanish saying "en abril, aguas mil" here, showers genuinely common across the whole country this month and northern Spain's own coast no exception, rain a real, expected part of any April visit rather than a surprise. Our row backs that cool, genuinely wet read, 16C over 10.3C nights feeling 8C, with 75mm of rain across 9.2 days and humidity at 78 percent. Regulars are consistent this remains a workable month for exploring the nearby Picos de Europa mountains despite the rain risk, proper waterproof layers the standard advice for any outdoor plans. The sea stays genuinely cold this early, nowhere near ready for swimming regardless of how mild an individual day feels. The sea sits at 14.3C. The record: 10.3 hours of sun, a 19.2 kph wind and AQI 53.

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.
