The Lowdown
Alright, Rusty here. Let's get into it.
For the next 16 days at Praia da Boraceia, it’s a slow start. Real slow. The first week is a grind, with only tiny, weak waves and mainly onshore or poor conditions. The energy just isn't there. There’s a fair gap from the start until the 4th of August where you’re really just looking at knee-high slop. The real action, the standout, doesn’t build until the second week.
The water is sitting at 70°, which is a touch warmer than usual for this time of year – about 2° above average, so it’s comfortable.
The first real flicker of life comes early on Tuesday the 4th. A 0.3m south swell rolls in with a 13-second period, and clean offshore wind from the NNW. It’s still tiny, though. The combined energy is only 85, so it’s weak. More of a longboard session than anything to get excited about.
Wednesday the 5th morning is a similar story. The swell builds to 0.7m from the south, period hangs at 11 seconds, and it’s glassy with a light W wind. The energy is moderate at 181, but it’s still a small wave. The afternoon gets a cross-on wind and messes it up.
Thursday the 6th and Friday the 7th offer slight improvements, but the swell stays small and inconsistent. You’re looking at 0.5m to 0.6m, with clean offshore winds, but the energy is weak to moderate. Saturday the 8th and Sunday the 9th are a write-off – either too small, or the wind is onshore.
Now, hold on to your board. The real pulse hits on Tuesday the 11th of August. This is the standout. The morning kicks off with a 7ft south swell, clean as a whistle with glassy conditions and zero wind. Combined energy is a strong 843. This is a proper groundswell with a 10-second period, and it’s just walling up. It’s a bit much for beginners – over 5ft – but for the experienced crew, this is the best of the period. The afternoon holds steady at 7ft with a 11-second period, and the energy jumps to 908. Still glassy. Unreal.
Wednesday the 12th sees a monster swell building, but the wind swings onshore. The swell hits 7ft to 7ft from the south, period jumps to 14 seconds, and the energy is huge – 1589 to 1699. That’s a lot of water moving, but it’s going to be a choppy, lumpy mess with the SE and S cross-on winds. The period is so long (over 15 seconds) that this might be better suited for a point break or reef, if there was one, but here it’s going to be a closeout. This is for experts only, and even then, it’s a survival session.
Thursday the 14th and Friday the 15th are still big, but the winds stay onshore. The energy remains high, but the surf will be messy. Saturday the 15th morning is a redemption. The swell drops to 5ft from the SSE, period is 12 seconds, and it’s glassy with light E wind. Energy is 639. This is another great window for experienced surfers. The afternoon drops to 4ft, still clean.
The 16th and 17th have some fun, clean waves, with a 7ft east swell on the morning of the 17th, glassy conditions, and energy at 812. That’s a strong, clean wave again, but the east direction might not be as ideal as the south swells.
Overall, the best bet by far is the 11th and 15th of August. The 11th is the real standout – big, glassy, and powerful. The 15th is a close second. Don't bother with the first week.
Rusty signing out.
