Conditions at Oyambre in July
July: Peak Summer Flatness and the Grovel Factor
July is the weakest month of the year for wave quality at Oyambre. The average swell is just 1.0m (3ft) and the average period sinks to 8.7s, the shortest of the year. Direction is still good - NW (53.1%) and NNW (28.9%) make up the bulk of the wave rose - but the energy is small, wind-driven and often shapeless. Semi-consistent 0.5-1.5m (2-5ft) waves are the norm, with a precious few head-high days when a strong NW windswell develops in the Bay of Biscay.
Ideal wind sits at just 15%, and ENE (13.5%) and NE (12.6%) winds are present on many afternoons, putting an onshore/cross-shore tilt on the wave faces. There is also a healthy dose of NW and NNW wind, which can clean up the smaller peaks if it stays light, but it rarely offers the offshore flow Oyambre needs. On the bright side, water temp reaches 20.5°C, air temp 19.9°C and precipitation is low at 1.13 mm/day. July is warm-up season, not score season.
