The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Barrinha. It’s been a bit quiet, but we’ve got some real promise hiding in the second week if you’re patient.
The first week is a write-off for any decent surf. From now until the 23rd of July, we’re looking at tiny, weak waves and mostly poor conditions. There’s a long gap here with nothing worth paddling out for, so save your energy.
Things finally start to stir on Thursday the 23rd. The morning brings a jump in size with a 8ft swell from the south, but it’s a bit of a messy one. The combined energy is strong (1426), but the winds are cross-offshore, so it’ll be clean enough for a session. This is more for the intermediate crew. Afternoon drops a bit to 6ft and the energy fades (599), still surfable but not the standout.
The real standout, and the one you want to circle on the calendar, is Sunday the 26th of July. Barrinha is a very consistent spot, and it’s fairly exposed to the south. The morning shows a solid 7ft swell from the ESE with a combined energy of 1158 — that’s some serious grunt. The wind is offshore from the southwest, so you’re looking at clean, lined-up waves. This is the best on offer, no question. It’s a bit big for the beginners, but for the intermediates, this is the session. It can get crowded here sometimes, so get in early.
The Monday morning after that, the 27th, is another beauty. The swell drops a touch to 6ft from the ESE, but the energy is still pumping (705) and the wind goes glassy from the northwest. That’s a rare treat — clean, glassy waves with decent size. Perfect for a morning mission.
After that, the surf fades quickly. By Tuesday the 28th, the wind turns onshore and choppy, and the size drops. The rest of the run into early August is mostly small, weak, and poor. There’s a little bump on the 3rd of August, but it’s all cross-onshore and messy — not worth it.
Water temperature is about average for the time of year, so no need for a thick wetsuit.
So, to sum it up: the first week is a dud. The standout is Sunday the 26th and Monday the 27th. Don’t miss it.
Rusty.

Information about the Barrinha Surf forecast
The above surf forecast table for Barrinha provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Barrinha can be found by selecting the local surf guide option on the grey menu. Our Barrinha 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 (Barrinha) 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 Barrinha 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.
