The Lowdown
Alright, let’s get into it. Over the next couple of weeks, Biologia is mostly a quiet affair, but there are a few sessions that’ll get your attention. The water's sitting at 50°F, which is a touch warmer than average for this time of year — nothing too crazy, just a bit more comfortable than usual.
The first real chance to paddle out comes Tuesday, August 25th, with the morning session at Biologia. A clean 1ft swell out of the SE, swinging cross-off with a moderate breeze from the north. The wave energy is weak though, only 43 (combined energy of all swells directed here). It’s super small, so you’ll be hunting for anything rideable — but it’s clean, and for a beginner spot that’s very consistent, you could get a few fun ones.
Wednesday, August 26th, brings a bit more size. The morning sees 6ft SE swell, but it’s a long-period 16-second groundswell moving in with a combined energy of 1402 — that’s strong energy. That long period will make the waves fat and powerful, so it’ll be better for a point break like Biologia than a beach break. Wind is cross-off from the NNE, moderate, and it’s clean. This is the standout of the whole outlook. Best session all week. Keep in mind, with 6ft, it’s still fine for most intermediate surfers, but beginners might find it a bit much.
After that, the swell drops off fast. Thursday, August 27th, is still surfable, with 4ft SE swell in the morning, cross-off NNW wind at just 3 mph, and clean conditions. The energy is moderate at 360. Thursday afternoon winds swing SW, light, still clean. But by Friday, August 28th, it’s down to small 2ft waves and weak energy (109). The rest of the forecast is a long stretch of poor surf from Friday afternoon all the way through to September 9th. Waves hover around 1ft to 2ft, with weak energy, mostly out of the east or northeast. There are a few clean windows with offshore winds, but the size just isn’t there. It’s a big gap of over a week with nothing worth paddling out for.
So, if you’re keen, aim for Wednesday morning, August 26th — that’s the closest thing to a proper session in this whole 16-day window.
