Conditions at Praia da Vieira in July
July: Small Summer Swell and Maximum NNW Wind
July is statistically the slowest month of the year. The average swell height bottoms out at 4ft (1.3m) and the average period at 8.7s. Despite the low energy, the swell direction is still favorable-NW holds 50.4% and NNW 31.1%, with WNW contributing another 15.1%-but most of that is short-period, mid-range windswell in the 2-5ft (0.5-1.5m) range. The wind is the bigger problem: NNW registers a staggering 59.1% of the time, while the ideal offshore wind drops to a yearly low of 5%. The constant cross/onshore flow makes the wave face lumpy and hard to surf. Water temp holds at 17.8°C, air temps average 20.9°C with minimal precipitation (0.28 mm/day), so it's a beautiful beach-but if you want quality surf, it's time to chase a rare summer tropical system or accept micro-groveling conditions in a 2/2 wetsuit.
