The Lowdown
G’day, I’m Rusty. I’ve gone through the numbers for the next 16 days at Praia do Norte, and I’ll level with you: it’s not a pretty picture. The wind is a constant problem, and the swell is either small or messy. There’s no real "go" day here, but a couple of windows might get you wet. The first chance is on Wednesday morning, August 19, and then a long dry spell until the end of the period.
First up, Tuesday morning, August 18 offers a 5ft swell from the NNW, with a short period of 8 seconds. Combined swell energy is a weak 285. The wind is a 9 mph cross-shore from the SSW, so it’s a bit choppy. The afternoon gets worse with 12 mph cross-onshore wind.
Wednesday morning, August 19 is the cleanest moment in the whole outlook. The swell is a tiny 3ft from the NNW, period 7 seconds, combined energy a paltry 139. The wind goes glassy – a 3 mph offshore from the SSW. It’s small and weak, but it’s clean. The water temperature is about average for the time of year. Afternoon turns cross-onshore and choppy again.
From Thursday, August 20 all the way through to Saturday, August 29, it’s mostly a dead zone. The one exception is Saturday morning, August 29 – a 5ft swell from the NNW at 9 seconds, combined energy moderate at 404. The wind is a light 3 mph onshore from the west, so it’s a little bumpy, but there’s more power. The afternoon gets choppy with 12 mph cross-onshore wind.
The final chance lands on Monday morning, August 31. This one has size – 8ft from the NNW at 9 seconds, combined energy climbing to 953 – so it’s a heavy wave. The wind is 6 mph onshore from the west, and it’s marginal. Over 8ft, this is expert-only territory. The period is under 11 seconds, so it’s not a deep groundswell, but there’s plenty of energy. The morning is the only window before the wind picks up.
If you’re looking for a wave, Wednesday morning, August 19 is your best bet for clean conditions, even if it’s knee-high. For the more experienced, Monday morning, August 31 has the size but watch that onshore wind. Honestly, the strong cross-shore winds and lumpy conditions on offer most days look better for kite surfing than paddle surfing.

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