The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Navegantes over the next couple of weeks.
Right off the bat, the first day or two are a bit of a write-off. Monday morning the 17th is a no-go with weak, crumbly 5ft ENE swell and a cross wind, and the afternoon is even worse. That gets us off to a slow start, and it takes until Tuesday morning the 18th to see anything worth paddling out for. The energy is still moderate (208), but a light cross-offshore breeze from the NW cleans up the 4ft ENE swell, making it a decent session for intermediates. Tuesday afternoon, the wind switches and the quality drops again.
There’s a real gap here through Wednesday and Thursday. The swell drops to under 3ft, and even with some glassy conditions on Wednesday morning, the waves are just too weak and ordinary to get excited about. Thursday is a total loss with poor conditions and tiny, low-energy swell (67 to 98). So we’re looking at a few days of flat, uninspiring water.
Now, Friday the 21st offers a small glimmer in the morning. It’s still only 3ft from the ENE, but we get a clean offshore breeze from the WSW. The energy is just about moderate (101), and the waves are surfable, but it’s nothing to write home about. Saturday morning the 22nd is glassy, but again, the swell is tiny at 3ft. The energy is still weak (131). It’s ordinary, but if you’re desperate, you can get wet.
The pattern really starts to shift as we head into the following week. Sunday the 23rd has a glassy morning, but the swell is still small and the period is increasing to 12 seconds, which is more of a groundswell. The energy climbs a bit to 159. Still not a standout, but it’s a sign of change.
The real standout window opens up on Tuesday the 25th. We get a clean offshore breeze from the WSW, 3ft of SE swell with a 13-second period, and the energy jumps to 237. This is the first genuinely good session in the forecast. The waves are clean, the swell direction is closer to the optimum SE, and the longer period gives them some push. Crowds are possible at Navegantes, but with conditions like this, it’s worth the company.
The next real highlight arrives on Thursday the 27th. The morning brings a 5ft E swell with a 8-second period, a light cross-offshore wind from the NW, and strong energy at 248. This is a much more powerful, punchy wave. The same holds for Friday the 28th morning, with a 5ft E swell, clean cross-offshore wind, and energy jumping to 347. This is the best on offer in the entire forecast. The swell is solid, the wind is right, and the waves have some real push. Saturday the 29th morning is also promising with a 4ft E swell, clean conditions, and energy at 255.
Looking further out, the last day of the month, Sunday the 31st, is a wild card. The morning shows a 7ft SE swell with a long 16-second period, but the energy is massive at 2130. The wind is light and cross-shore, but at that size and period, this is strictly for experts. The swell may be too big and the long period could make it close out at the beach. The afternoon glassy session with 3ft SE swell and 470 energy is actually a much more user-friendly option, but it’s hard to trust the consistency that far out.
Overall, the best bet is to target the mornings from the 25th through the 29th, with Friday the 28th being the clear standout. The water temp is about 66° and the anomaly is only +0.7°, so it’s what you’d expect for this time of year, no surprises there.
Rusty.

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.
