The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on offer at Montoya over the next couple of weeks.
Honestly, it’s a pretty quiet spell for Montoya. The first few days are a write-off with that long-period SE groundswell packing a heap of energy but blown out by a cross-breeze and lumpy conditions. That swell is 5ft with a 15-second period, so it’ll be tempting, but the NE wind at 12 mph is going to mess it up. The water temp is about average for this time of year, so nothing weird there.
We won’t see anything really good until Thursday, 27th August. That morning, the swell drops to a cleaner 3ft from the SE with a 13-second period, and crucially, we get a light N wind at 6 mph that’s cross-offshore. The wave energy is moderate, and the conditions should be clean—definitely your best window in the whole run. It’ll offer some fun lines for intermediate surfers. It’s a beach and point setup, so that longer period will work nicely, and it’s fairly consistent. Crowds are sometimes a thing here, so you might have company.
The rest of the run is grim. From Thursday afternoon right through to the end of the forecast, it’s plagued by onshore wind, mostly from the east, with tiny swell (mostly under 3ft) and short periods. The wind stays cross-on or directly onshore, making it choppy and mostly unsurfable. There are stretches of days with zero recommendations—like from the 28th of August right through to the 2nd of September, that’s a solid week of poor conditions.
The only other faint glimmer is on Thursday, 3rd September morning. We get a 5ft SSE swell with a 12-second period, and a light NNE wind at 9 mph swinging cross-offshore. It’s clean, but the forecast is marginal and the tide could be a problem. Worth a look if you’re desperate, but it’s not a standout.
Overall, if you’ve got to surf, Thursday the 27th of August morning is the call. Other than that, it’s a waiting game.
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.
