The Lowdown
Alright, Rusty here, checking in on the surf. Let’s break down what’s happening over the next couple of weeks.
We’ve got a slow start. Wednesday afternoon has a small, clean window at Montoya with a 0.7m easterly windswell and a light offshore breeze. The water is a touch warmer than usual for this time of year, sitting around 13°. The energy is weak (78), so it’s a longboard day if you’re desperate. After that, things go quiet.
From Thursday morning all the way through the second week, the surf is mostly poor. We’ve got a lot of messy wind – cross-shore, cross-on, and a strong onshore blow on the 6th of September that brings in a big, raw 3.5m storm swell (energy at 2098). That’s too big for most and the conditions are junk. For the next week and a half, the waves are small, blown out, or both. There’s a long stretch of days with nothing worth paddling for.
The only real standout in this whole 16-day window is Thursday morning, the 17th of September. We’ve got a clean 1.5m south groundswell with an 11-second period, light offshore wind, and solid energy (568). That’s the one to aim for. It’s a ways out, so don’t book the day off yet, but if it holds, that’s your best bet.
Everything else is either small, messy, or a total washout. For a place that’s fairly consistent, this is a pretty lean run. Stick with it, and keep an eye on that 17th.
Rusty.

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