The Lowdown
Alright folks, Rusty here, breakin’ down the next couple weeks at Punta Negra. It’s gonna test your patience. The first week and a half is pretty much a bust, with stretches of days where there’s no real surf on offer. Things finally get interesting around Monday the 14th, but it’s still small.
The water temp is normal for the season, nothing to write home about.
Monday morning the 14th sees a light offshore wind (NNW) cleaning up a small 3ft SSE swell (9 seconds). The energy is weak (123). You might get a few fun ones if you’re desperate. Conditions stay clean-ish into the afternoon.
Your absolute best window is Thursday the 17th. That morning, we get a clean 3ft groundswell from the south, long 11-second period, with a light offshore breeze from the NW. The energy is moderate (367). This is the day. The waves will have shape, the wind will be perfect. Get out there. The afternoon gets more cross-on wind, but the swell energy actually jumps up higher (514).
Friday the 18th is still worth a look with 4ft swell and clean cross-off winds, but it's a touch smaller than Thursday’s peak.
After that, it’s game over. Small, messy surf from Saturday onward. Nothin’ else to get excited about.
Mark your calendar for Thursday the 17th. That’s the one.
Rusty, out.

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