Table - best surf conditions forecast for Montoya over the next 16 days.
The Lowdown
Alright, let’s have a look at what’s on offer. Honestly, it’s a pretty quiet stretch ahead. There’s a tiny window of decent surf, but the rest of the run is looking ordinary. The water sits at around 51°F, which is about normal for this time of year – nothing unusual there.
The one real standout comes up on Thursday the 27th of August. Early that morning we’ve got a glassy setup at Montoya, with a 3ft swell pushing in from the southeast, packing a period of 13 seconds. That’s a nice long-period groundswell, and with the wind going glassy, it’s about as clean as you’ll get. The combined energy sits at 376 (moderate), so there’s some life in the water. Conditions are expected to be good. Montoya is a beach and point setup, so that long-period swell should wrap in nicely for some lined-up waves, though it might be a little better on the point. Keep an eye out for crowds, as they can show up sometimes.
After that, it’s a long, dry spell. From Thursday afternoon right through to the end of the forecast window, it’s mostly poor surf conditions with small, messy swell and cross-onshore or onshore winds. There’s a brief moment on the morning of Wednesday the 2nd of September where the swell bumps up to 5ft from the SSW, but with a short period of 6 seconds and a cross-shore wind, it’s just too choppy and disorganised to get excited about. The energy reads 258 (moderate), but the quality just isn’t there.
The morning of Thursday the 3rd of September has a small 3ft S swell with a clean cross-off breeze, but it’s tiny and ordinary. And again on the morning of Friday the 4th of September, a 2ft glassy S swell is on offer, but it’s barely worth paddling out for. The rest of the run into the second week is all small, wind-affected, and low-energy – combined energy values mostly under 200, with periods often under 10 seconds. There’s a bit of a bump in the middle of the second week around the 9th and 10th of September, with swell heights of 5ft to 5ft from the SE, but the wind is cross-onshore and choppy, so it’s not going to be a pretty picture.
So, bottom line: if you can get out on the morning of the 27th, that’s your best bet. After that, it’s a long wait for anything worthwhile.

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.
