Conditions at Guethary in July
July: The Deepest Summer Slump
July is the absolute bottom of the surf calendar in terms of power. Average wave height remains at 3ft (0.9m) but the period drops to the yearly low of 9.0s. The wave rose is even more NW-heavy: NW at 66.5%, WNW at 27.3% and NNW at 5.7%. It all means you are looking at soft, windswell-like lines with occasional 3-5ft (1-1.5m) NW groundswell when an Atlantic low wanders by. The direction is right, but the energy is just not there.
Wind makes it harder still. Ideal conditions occur only 15% of the time - the lowest of the year - as the onshore N/NW gradient dominates: NNW 18.2%, WNW 18.7%, NW 17.9% and W 12.4%. Water temp is warm at 22.1°C and air temps average 20.0°C, so it feels like summer even when the surf is small. For an experienced surfer, July is a good month to rest and wait, or to ride a longboard in the lukewarm creamy leftovers.
