Conditions at Cova do Vapor in July
July: Peak Summer Doldrums
July is the slowest month at Cova do Vapor, statistically speaking. The average swell height bottoms out at 1.0m (3.3ft) and the period drops to 8.7s-the shortest of the year. The wave rose is remarkably one-dimensional: NW (67.3%) and WNW (23.8%) account for over 90% of all energy, with only a tiny 3.3% from the W and 0.3% from WSW. The wind is ideal just 28% of the time, and the famous summer NNW flow (63.9%) is often blowing 20-30kph. While the direction is technically offshore, it makes 2ft summer slop lumpy and hard to ride. Water temps climb to 17.5°C, air to 20.0°C, and precipitation is nearly zero at 0.11mm/day. Surfing is possible on the rare clean morning or when a rogue south-angled swell slips in, but this is a month for longboard fun and low expectations.
