The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
Honestly, the first week is a bit of a slow grind. The opening days are pretty lackluster, with small, messy windswell and onshore breezes making a mess of things. We’ve got a few days of clean, tiny surf, but nothing to get excited about. The real standout is hiding in the second week, and it’s a beauty.
The water temp is about average for this time of year, so no need for a thick wetsuit just yet.
If you’re patient, Sunday, 29th August is the day to circle. We’ll see a solid pulse of NW groundswell rolling in, with the morning offering up 6 ft faces from the NW. The wind is light and cross-off from the SSW, which will keep the lines clean at Santa Maria de Oia. This is an advanced reef break, so it’s not for the faint of heart, but it's a proper session for the experienced crew. The combined energy is strong at 586. The afternoon holds a bit more size at 8 ft from the NW, but the wind swings cross-shore, so it’ll be a bit more wobbly. That morning window is the pick.
The following day, Monday, 31st August, is also worth a mention. The swell drops a touch to 5 ft from the NW, but the wind goes glassy from the south early. That’s a recipe for clean, punchy waves on the reef. It’s a solid backup option.
Before that, Sunday, 23rd August gives us a brief improvement. The morning sees 5 ft of NW swell with light, clean cross-off winds from the ESE. The wave energy is moderate at 251. It’s a good, surfable option ahead of the main event.
The tail end of the month is a bit of a damp squib, with small, choppy waves and onshore winds. Stick to the 29th and 31st for the real action.
Rusty.
