The Lowdown
Alright, my friends, let’s break this down. The start of this stretch is grim, just a whole lot of nothing. The first couple of days are blown out and messy, not worth your time.
But then, Monday, September 7th, the ocean remembers how to surf. We get a 1.2m SSW swell at Montoya, but the real gift is that light offshore N wind. It’s clean, it's got shape, and it’s the best wave we’ve seen in a while. The energy is moderate, around 228, and that point break will be holding the sets nicely. This is a solid call if you can get out.
But don’t get too used to it. The surf is about to vanish. We hit a serious flat spell from the 8th through to the 11th. Tiny, weak waves and a lot of chop. It’s a dead zone, and you're better off doing something else.
Here’s the part you’ve been waiting for. The swell starts to build on the 13th, but the wind is all over the place. It’s not until Monday, September 14th that it all comes together. This is the one. We have a clean 1.3m E swell, 11-second period, and it's glassy, dead flat. No wind. This is your window. The energy is strong, sitting around 553, and the east swell is perfect for Montoya. This is the true standout, the best we’re going to see.
The 17th also has some clean morning waves with a smaller SSE swell, but it’s not in the same league as the 14th. It’s a decent backup, but not the main event.
That 14th is the one to circle on the calendar. Don't blow it. The end of the forecast turns small and less reliable, so that Monday morning is your best bet for real quality.
Rusty out.

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.
