The Lowdown
Alright, grab your board and listen up. This is Rusty, and I’m looking at the next 16 days for our little slice of coast. The surf starts off pretty slow, but there’s a real pulse of energy building next week that’s got my attention. The water's sitting about average for this time of year.
It’s a quiet start. Saturday the 5th and Sunday the 6th are pretty flat and messy. We’ve got small 3ft to 8ft swell from the south, but the wind is howling out of the SSW on Sunday, gusting to 19 mph, and the combined energy is strong (426 to 1212) but it’s just too rough. Don’t bother paddling out. There’s a couple of days of small, poor surf after that, with waves barely reaching 4ft on Tuesday the 8th. The wait is worth it though.
Monday the 7th morning is the first real flicker of hope. The swell is 6ft from the south, the wind is light offshore out of the SW at 6 mph, and the combined energy is moderate (579). The report says "expect good surf conditions" and the waves are clean. It’s not a classic, but it’s a proper session.
The real standout is the run from Saturday the 12th onwards. Saturday afternoon sees a jump in size: 10ft of swell from the SSW with a 12 mph offshore wind from the WSW. The combined energy is massive (1547) and the conditions are clean. But here’s the thing – 10ft is big, and the report flags it as too big for this break. This is for experienced surfers only. The trend continues into Sunday the 13th with similar 10ft swell and strong offshore winds, though the energy is even higher (1804 to 1829).
Then, Monday the 14th. This is the best on offer. The morning is clear with a 8ft swell from the SSE, and a gentle offshore breeze from the SW at 9 mph. The period is a lovely 12 seconds, bringing proper groundswell energy. The combined energy is very strong (1609), and the report says "excellent surf conditions for experienced surfers." This is a session for the crew who know what they’re doing. The swell direction (SSE) is not quite the optimum SE, but the quality and wind make it the pick.
Wednesday the 16th morning is another solid option. You’ve got 7ft from the SE with a 13-second period, light offshore wind from the south at 3 mph, and the energy is strong (1367). The report again says "excellent surf conditions for experienced surfers." The conditions are clean, and the swell is serious.
Things back off towards the end of the window. The morning of Friday the 18th is a nice surprise – 5ft from the south, glassy conditions with a light SSW wind, and the energy is moderate (946). The report says "expect very good surf conditions." This is a fun, manageable size for a wider range of surfers, and the glassy conditions are a major positive.
After that, the swell drops right off, with small, weak waves and poor conditions from the 19th onwards. It’s a solid run of surf, but don’t sleep on that Monday the 14th session.
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.
