The Lowdown
Alright folks, Rusty here. Let's have a look at what Galheta is cooking up over the next couple of weeks. It's a bit of a slow burn, so bear with me.
First up, the water temp is sitting at 65°, which is about average for this time of year. Not a shocker there.
The outlook starts quiet. Tuesday and Wednesday are basically a washout with tiny, weak swell and poor surf conditions. We're talking next to nothing, just a few 0.3ft to 1ft waves with short periods. The energy is basically non-existent, with readings down at 3 (Tuesday) and 33 (Wednesday afternoon). Not worth paddling out for.
Thursday the 20th and Friday the 21st see a slight bump in swell, but it's still mediocre. The morning of the 20th has a tiny 3ft swell from the ENE, but the combined energy is only 94, so it's weak. The wind is clean, but the waves are just too ordinary to get excited about.
Then we hit a real dead zone. From Saturday the 22nd all the way through the morning of Monday the 31st of August, there's a massive gap with no real surf to speak of. The models are showing flat spells, and the wind is all over the place. It's a proper blank run.
Finally, the light at the end of the tunnel. The afternoon of Monday the 31st of August is the first real standout. The swell jumps to 5ft from the East, with a period of 8 seconds. The combined energy is a solid 302 (moderate), and the wind is a light offshore from the North. That's clean, glassy conditions. This is the best on offer, but keep in mind that at 5ft, it might be a bit much for absolute beginners.
Looking further ahead to the 2nd of September, Wednesday morning and afternoon look promising. We're looking at 3ft of ENE swell with a 9-second period, and the combined energy is around 212-234. The morning is glassy and the afternoon has a clean cross-offshore breeze. That's a solid, fun size for an intermediate surfer, and it's another good option.
So, to sum it up: there's a lot of flat to get through, but the afternoon of the 31st of August and the 2nd of September are the days to circle. The rest of the forecast looks like a write-off for paddle surfing.
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.
