The Lowdown
Hey, Rusty here again for the imperial version.
Water temp is 62°F, about 4°F colder than usual for this time of year—so it’s noticeably chilly. You’ll want a good wetsuit.
We start off Sunday afternoon (13th September) with waves around 5ft from the south, but the period is only 7 seconds—weak and short-period. Wind is cross-off at 12 mph, making it a bit bumpy. Combined energy is 257 (moderate). Not the best start.
Monday morning (14th September) is much better. We’ve got 4ft south swell with an 11-second period—that’s proper groundswell. Wind goes offshore at 9 mph, so it’ll be clean. Combined energy is 460 (moderate-to-strong). This is a solid session for Barrinha. Crowds are possible.
Monday afternoon stays clean but drops to 4ft.
Tuesday (15th September) is smaller, around 3-3ft, with cross-off winds. Rideable but not special.
Wednesday morning (16th September) brings 6ft from the south, period 8 seconds, light cross-off wind at 6 mph. Energy is 444 (moderate). Morning is the go—afternoon gets blown out at 16 mph.
Thursday (17th September) has 5-6ft but cross-on winds make it choppy. Not worth it.
Friday (18th September) through Monday (21st) is flat and poor. Swell drops to 0.7ft or less, winds onshore. Even with glassy conditions on Monday morning, there’s nothing to ride. Energy is as low as 7 (weak). This is a real lull.
Second week picks up. Tuesday morning (22nd September) brings a new 5ft east swell, period 9 seconds, light cross-off winds at 6 mph. Energy 385 (moderate). Clean and fun. Wednesday (23rd) is similar with 4-4ft.
Thursday (24th) and Friday (25th) get messy with cross-on winds again.
Saturday (26th September) has some glassy conditions in the morning with 2ft from the southeast, but energy is low (86). Afternoon has 4ft from the east-southeast but only 6-second period—junky.
Sunday (27th September) bumps to 6ft from the east-southeast, but wind hits 16 mph cross-off. Energy 466 (moderate). Could be more of a kite day.
The best session is Monday morning (28th September): 5ft from the east, 8-second period, glassy winds. Energy 362 (moderate). Clean, small, and fun. Afternoon stays glassy at 3ft.
So, first week has a few clean windows on Monday 14th and Wednesday 16th mornings. Second week looks good from Tuesday 22nd to Wednesday 23rd, with the absolute standout being Monday 28th under glassy conditions.
Don’t bother during the flat spell mid-month. Keep an eye on the forecasts.
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.
