Conditions at Sao Juliao in July
July: Peak Summer Slop
July is the slowest month at Sao Juliao. The average swell height bottoms out at 1.4m (4.6ft) with an 8.5s period, and a remarkable 54.2% of the waves come from the NNW, with NW adding another 33.0%. This angle is far from ideal for the west-northwest-facing beach, and most of it is short-period windswell generated locally rather than distant storm energy. Wind conditions are even less favorable: NNW winds howl 59.4% of the time, and offshore windows from the east/southeast are essentially nonexistent at 2% of the time. The few rideable moments come at first light before the Atlantic breeze fills in, or on rare days when a weak afternoon sea-breeze actually cleans up the small side-shore lines. Water temp sits at 17.4°C, air averages 20.2°C, and rainfall is just 0.15 mm/day. Leave the shortboard at home and bring a funboard or longboard.
