Conditions at Mundaka in June
June: The Summer Lull Takes Hold
June is the beginning of Mundaka's slow season. Average swell drops to 3ft (1.0m), with periods easing to 9.1s. What remains is overwhelmingly windswell from the northwest: NW accounts for 54.0% of all readings, with NNW at 21.6% and WNW at 17.3%. Nearly half the swell is in the 2-3ft (0.5-1m) range, and the wave lacks the juice to allow the river mouth sandbar to perform at its best.
Wind patterns become more influenced by thermal effects than winter storms. NE and ENE winds combine for nearly 19% of the time, and while these are not directly onshore at Mundaka, they add cross-chop on the outside. The best windows occur when a weak S/SSW flow develops in the afternoon or when dawn breaks windless. With ideal wind only 16% of the time, June is mostly a longboard/small-wave month. Air temperatures reach 18.0°C, water temperature is 19.1°C, and the lower precipitation of 2.00mm/day creates plenty of sunny, idle hours between sets-but don't expect Mundaka to be firing.
