The Lowdown
G’day, Rusty here. We’ve got a solid run of surf ahead at Rio Nexpa, a classic point river-mouth setup that’s very consistent and loves a good SW swell. The water temp is about average for this time of year, so nothing crazy.
The opening days deliver clean, rideable waves. Tuesday morning, 18 August, sees a light 4ft SW groundswell rolling in with a long 14-second period, and with glassy conditions from a NE breeze, it’s going to be super clean—perfect for intermediates. The combined swell energy is solid at 537 (moderate wave energy). Afternoons kick up a cross-on wind, so the mornings are where it’s at.
Wednesday morning, 19 August, keeps the vibe going: 3ft SSW swell, still glassy, beautiful shape potential. Thursday and Friday mornings offer smaller 3ft SSW swell, but with glassy or clean conditions, there’s still fun waves for a patient surfer. Thursday afternoon is marginal, but don’t let that put you off.
Now, the standout window opens Sunday morning, 23 August. We’ve got a 3ft SSW groundswell, a period of 14 seconds, and glassy winds. The combined energy jumps to 780 (moderate), and conditions are lined up for very good surf. This is a serious session if you can get out there.
Monday 24 August morning offers a cleaner 2ft SW swell but with a very long 17-second period—that’s proper groundswell energy (617 combined), and with cross-off winds, the point will hold nice lines. Be aware that this long period setup can make waves break a bit straight on a river mouth, but Rio Nexpa handles it well.
The real sizzler comes Saturday morning, 29 August. Swell builds to 5ft from the SSW, period at 16 seconds, combined energy hits 1416 (strong wave energy). Winds are light and cross-off, making for excellent, clean conditions. This is only for experienced surfers at this size—5ft is solid and punchy here. The point should offer proper waves.
Sunday morning, 30 August, stays chunky with 5ft SSW swell, still clean, energy at 1196. Another excellent morning if you want to skip the afternoon chop. Into early September, Tuesday morning 1 September brings a 4ft SSW swell, clean, with very good conditions—a nice way to finish the run.
Crowds are often a factor here, so expect company on the best mornings. Don’t bother with afternoons—cross-on winds carve them up.

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