Conditions at Bico in July
July: Summer Flat Days and Dawn Patrol Runs
July is Bico's quietest month on paper. The average swell bottoms out at 1.0m (around 3ft) with an average period of just 8.7s, which means the ocean is dominated by shorter-period NW/NNW windswell rather than true long-period groundswell. NW swell accounts for a massive 67% of the directional total, but with heights mostly in the 0.5-1m range, expect small, soft, crumbly conditions.
The wind statistics are brutal for quality: just 4% ideal conditions, while onshore NNW flow dominates an incredible 57% of the time. Classic summer on the Portuguese coast: mornings are often cleaner, but once the sun heats the land, the seabreeze chops things up. Air temperatures are warm, averaging 20.0°C with highs pushing 33.0°C, and water temps are a pleasant 17.3°C. If you're chasing waves, go at first light with a longboard; if you're chasing sun, July is perfect.
