The Lowdown
G’day, Rusty here, and I’ve had a good look at what’s coming for Navegantes. Straight up, it’s a lean stretch. The first few days are pretty ordinary and there’s a real gap from the get-go with no recommended surf until the 18th, so we’re looking at a quiet start. The standout for the whole run is Wednesday morning, 19th August, when conditions line up best.
Alright, let’s paddle into it. The first sniff of anything rideable hits Tuesday morning, 18th August. Navegantes is a beach-and-jetty setup, exposed to swell, and it’s very consistent, so breaks are reliable even if the size is small. The water’s sitting at 66°, with a tiny anomaly of 0.7°, so it’s about average for this time of year—nothing wild. Tuesday morning brings a clean 4ft swell from the ENE, with a short 8-second period, so the waves are a bit crumbly, but the wind is cross-offshore from the NW at 6 mph, giving you clean lines. The combined energy is moderate at 208—not a lot of punch, but enough for a few fun ones. Tuesday afternoon drops to 4ft, same direction, but the wind goes cross-onshore from the NNE at 6 mph, so it gets a bit rippled.
Now, the best of the lot comes Wednesday morning, 19th August. The swell drops to 3ft from the ENE, still short period at 8 seconds, but the wind goes glassy, completely calm. That’s a major positive—clean, smooth conditions where you’ll see every ripple. The energy is light at 146, so it’s not a power day, but for a small wave, glassy conditions make it the pick of the fortnight. The water’s still the same temp, around 66°, nothing unusual. Wednesday afternoon turns choppy as the wind swings SE at 9 mph, cross-onshore, so that window is tight.
Thursday morning, 20th August, offers another glassy window with the wind from the north at 3 mph, but the swell is tiny at 3ft, ENE, with weak energy of 82. It’s surfable but very ordinary. After that, the week slides into a mix of offshores and small swell. Friday 21st has a cleaner offshore wind from the WSW, 9 mph in the morning and 16 mph in the afternoon, with swell around 3ft to 3ft, short period, energy moderate but nothing special—the afternoon wind is strong enough to keep it clean but a bit of a work-out.
The second week, from 24th August onwards, is a long, quiet stretch. The swell picks up a touch in period but not in size. Sunday 23rd sees a 4ft SE swell with a longer 11-second period and moderate energy of 280, but the wind is cross-shore or onshore, so it’s messy. Monday 24th and Tuesday 25th bring longer period swell, up to 14 seconds, with energy spiking to 460 on Tuesday morning, but the swell height is only 4ft, and the wind is cross or cross-onshore, so it’s not clean. That longer period at a beach break like Navegantes can make it break too straight, and the conditions aren’t dialled. From 26th August onwards, the swell drops to 2ft or less, with weak energy under 200, and the wind is either glassy or cross-onshore, but the waves are just too small to get excited about. There’s a gap of several days from 24th to the end where nothing really stands out, and by 30th August, it’s light rain and tiny 2ft swell with poor conditions.
So, the honest call: Wednesday morning, 19th August, is your best bet. Small but glassy, clean, and you’ll have a few fun ones to yourself at Navegantes. The rest of the run is a waiting game. Hang in there, and check the forecast again—things can change.
Rusty.

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