The Lowdown
Alright, let’s get into it. I’m looking at the charts for Montoya, and honestly, for most of this outlook, it’s going to be a waiting game – but there are a couple of windows that’ll get your blood pumping.
We’ve got a bit of a dry spell to kick things off. The first real sessionable window doesn’t open until Thursday morning, the 27th of August. That morning, a clean 3ft swell from the southeast, with a period around 13 seconds, slides in under a light offshore from the NNW. The water temp is sitting at a pretty average 52°F for this time of year – nothing unusual there. The combined energy is moderate at best (376), but for a short window, it’s clean.
After that, it’s a long, bleak stretch. From Thursday afternoon the 27th all the way through to the morning of Friday the 4th of September, it’s pretty much all poor surf with onshore or cross-shore winds ruining any potential. The swell sticks around, but it’s messy or small. There’s a bunch of days in that gap where you’re better off doing something else.
Now, here’s the standout. The morning of Friday, the 4th of September, finally lights up. Montoya sees a very clean 2ft swell from the SSE, but check the period – 15 seconds. That is a very long period groundswell. This thing will have some serious energy pushing in (combined energy of 201). The wind is a light offshore from the NNW. This is the best chance in the whole 16-day forecast. For a beach and point setup, that long period stuff will wrap around the point nicely and offer some proper shape. It’s going to be a small but high-quality wave. Because the swell is small, it is fine for intermediate surfers. But be aware – crowds are possible here.
After that brief window, we’re back into the wilderness. The rest of the forecast from the 5th of September onward is a punishing run of onshore winds from the east, thrashing the swell into choppy, wind-blown mess. The swell sticks around, but the quality is shot. A few swells in mid-September push the height over 5ft, but with the wind howling from the east, it’s just a washing machine. This setup in the beach sections is looking more interesting for kite surfing than paddle surfing.
So, the call is simple: if you can, get out on the morning of the 4th of September. That’s your only real highlight in this 16-day period. The rest is a write-off.

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.
