Conditions at Zarautz in July
July: Flabby Summer Waves
July is the slowest month of the year for Zarautz. The average swell height remains at 3ft (1.0m) but the period drops to 8.8s - the shortest average of the year. This is marginal, grovely surf even in the most favourable conditions. The direction is almost absurdly focused on the NW, with 65.3% from the NW, 16.4% from WNW and 16.4% from NNW, but the bulk of that swell sits in the 0.5-1m range, and there is virtually no energy above 2m. It is fat, slow and often close to flat in the summer heat.
Wind-wise, July is tough. The NNW breeze is the single most common wind direction at 17.8%, and NW adds 14.5%; combined with NNE at 12.8%, the summer sea breeze and synoptic flow are consistently onshore. The ideal S/SSW offshore is present only 4.4% of the time, and ideal conditions just 18%. Air temperature peaks at 20.0°C, water at 21.6°C, and precipitation is at a minimum. If the swell direction is right but the wind is wrong - which is most of the time - expect mess and closeouts. Summer surf in Zarautz is for the keen or the desperate.
