The Lowdown
Alright, let’s talk waves. Right now, it’s flat and ugly for the most part, but there’s a good week on the horizon if you’re patient.
We're looking at Galheta. This break can fire but it’s going to take a few days. Right off the bat, on the 16th, there’s a 6ft ENE swell but with short period, blown out by a cross-off breeze. Water temp is 65°, pretty normal for this time of year. Nothing to write home about.
Then it dries up. From the 17th through most of the following week, there’s nothing worth paddling out for. Tuesday morning the 18th gives you a brief window with a 5ft ENE swell and offshore wind – clean surf, decent energy (347) – but it’s gone by lunch.
The rest of that week is a mix of onshore wind, small swell, and poor conditions. The 26th brings a bit of windswell with 5ft and 6ft ENE swells but the period is short (6 seconds) and the wind is onshore. That’s more of a kiteboarding day than a surfing day.
Here’s where it gets good. Thursday morning the 27th of August: glassy conditions, a 6ft ENE swell, and the energy is strong (492). That’s the pick of the forecast – clean, powerful, and the offshore wind will make it a session to remember. Friday the 28th morning is almost as good: 6ft ENE swell, clean, with strong energy (473). Saturday the 29th carries it on with 6ft ENE swell and offshore wind in the morning.
After that, it fades. The 30th and 31st are smaller, messier, with onshore breezes. The 31st morning is glassy but only 4ft – surfable, but a step down.
If you’re keen, aim for that last week of August. That’s where the magic is.

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.
