The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – it’s a slow start and a long wait for the good stuff. The first recommendation for Barrinha doesn’t pop up until Tuesday, 1st September, so we’ve got a few days of small, messy, or just plain poor conditions to get through first. Friday the 28th and Saturday the 29th are write-offs with tiny, weak swell and cross-onshore breezes. Sunday the 30th is glassy in the morning but the swell is tiny and short-period, and the afternoon brings a bit more size but it’s onshore and lumpy. Monday the 31st is another day to skip – more onshore wind and weak waves.
Alright, now for the good bit. The real standout in this whole 16-day run is Tuesday, 1st September at Barrinha. The morning is clean with offshore cross-off winds from the SSW at 19 mph, and the swell is already a solid 8 ft from the SSW. But the afternoon is where it gets exciting – an 12 ft swell from the S with a period of 10 seconds and a massive combined energy reading of 1996. The wind stays clean and cross-off. However, this is a big one – at 12 ft, this is strictly for experienced surfers only. The wave comment says it’s too big for the break, but if you’re an expert and you know Barrinha, this is a serious, powerful groundswell that’ll be stacking up. The water’s sitting at 64°, a bit colder than normal for this time of year, so a good wetsuit is essential.
Wednesday the 2nd is still a good option. Morning has a 8 ft SSE swell with cross-off winds and the combined energy is still high at 1202. It’s clean and the waves are solid, but the afternoon gets a bit more cross-shore and the score drops. Thursday the 3rd is smaller but still rideable – 5 ft in the morning with clean conditions.
After that, it fades. From Friday the 4th through to Monday the 7th, it’s back to small, onshore slop with very few redeeming features. Tuesday the 8th brings a new pulse – a 7 ft swell from the ESE in the morning with light cross-off winds and clean conditions. It’s a decent option for intermediate surfers. Wednesday the 9th is onshore and messy.
So to sum up: the big, powerful, expert-only session is Tuesday 1st September afternoon. Wednesday 2nd morning is your next best bet for a strong, clean swell if the 12 ft is too much. Everything else is marginal or poor. That first week is a tough wait, but when it comes, it comes with a punch.

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.
