Conditions at Ribeira Quente in August
August: Ocean Calm and Island Heat
August remains trapped in the summer lull. The regional average swell is 4.3ft (1.3m) at 9.3 seconds, with the bulk of the energy coming from NNW and NW windswell. The bay sees very little of that, so the surf is generally clean and rideable but thoroughly small. Southerly swell sources are almost nonexistent, and those that do appear are under 1m (3.3ft) and from the low end of the period scale.
Offshore winds are still favorable 59 percent of the time from the NNE/NE quadrants. The ocean is at its warmest, 23.4°C, and air temps exceed 25°C. With precipitation just 0.75 mm/day, this is the heart of the Portuguese summer: flat mornings, glassy lagoons, and the hope of an opportunistic groundswell from a rogue Southern Hemisphere event - rare but not impossible.
