The Lowdown
Alright, Rusty here. Let's talk about what's happening at Galheta.
We got a slow start for a few days, nothing to write home about. But hold onto your board, because there's some real juice coming in the latter half of the month.
The first serious action kicks off early Friday morning, August 14th. We're looking at a solid 7ft south-southeast groundswell with a long 13-second period. That's proper groundswell with some good push. The combined energy is a strong 1286, so you'll feel it. And the best part? The wind is dead glassy, flat calm. It's going to be clean as a whistle, a real standout for experienced surfers. The water's sitting at around 65°, which is about average for this time of year, nothing wild. The southeast pulse carries into the afternoon, dropping to about 5ft, but staying glassy and clean.
Saturday the 15th and Sunday the 16th keep the fun rolling with solid 5ft to 6ft east-southeast swell and clean cross-off winds from the north. The energy stays moderate, in the 300 to 430 range. It's consistent, you'll get plenty of rides. Monday the 17th shows a bit more size and power (7ft at 578 energy), though the wind picks up from the north. It's still rideable, just not as perfect as Friday.
We hit a bit of a flat patch mid-week around the 20th and 21st. Conditions get ordinary, small and messy. Then mark your calendar for the second standout: Thursday, August 27th. Another strong southeast groundswell is forecast, this time 6ft at 14 seconds. The combined energy is a massive 1560, which is some serious power. On top of that, we get a nice offshore wind from the north, keeping the faces clean. This is a classic session for the experienced crew, as that size is over 8ft and too much for beginners.
It gets a bit junky at the tail end of August with small, onshore waves. The final few days of the second week look a little more interesting, but it's a long-range call, so don't hold your breath.
Bottom line: your absolute best window is the 14th of August, Friday morning, for glassy, powerful waves. The second standout to circle is the 27th of August, Thursday, for another quality, offshore groundswell.
Rusty.

Information about the Galheta Surf forecast
The above surf forecast table for Galheta provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Galheta can be found by selecting the local surf guide option on the grey menu. Our Galheta surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Galheta) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Galheta may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
