The Lowdown
Alright, let’s get into it.
Look, I’m gonna be straight with you. For Montoya, the next couple of weeks are a proper struggle. We’ve got a long, drawn-out patch of just about nothing worth paddling for. The first solid recommendation doesn't pop up until Sunday, August 9th, which leaves a big gap of over a week with no decent options. Before that, it’s all tiny, short-period slop with messy winds – onshores, cross-onshore, and some pretty fresh breezes that just kill any chance of a good wave. You’ll see a little spike in combined energy around August 3rd and 4th (293 and 233), but that’s coupled with brutal cross-onshore winds and lumpy conditions. No good.
Now, the standout. That Sunday, August 9th morning is your only real window. We’re looking at a 5ft swell rolling in from the south with a long, juicy 13-second period. That’s solid groundswell energy, with a combined energy reading of 787 – that’s strong. But the big win here is the wind: glassy, dead calm. That’s about as clean as it gets. The water temp is sitting at 54°F, which is a touch warmer than normal for this time of year, so that’s a nice little bonus. Keep in mind, that long period (13 secs) and south swell direction is going to wrap in nicely at the point at Montoya, but it might wall up and go a bit too straight on the beach section. The breaks will be cleaner and more lined up at the point. The crowd factor is listed as “sometimes” busy, so you might have to share, but for these conditions, it’s worth it.
That afternoon session on the 9th doesn’t look as good – the wind swings onshore and the conditions get questionable. By Monday the 10th, the wind is back onshore and chopping it up. So really, you’ve got one golden morning there on the 9th.
After that, August 12th shows a bit more size (5ft) but the wind is a fresh cross-shore, making it lumpy. Not the one.
So, to wrap it up: the forecast is pretty barren until Sunday, August 9th. If you can get out that morning for some clean, glassy, south swell at Montoya, you’ll have a proper session. Everything else in this 16-day window is a write-off.

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.
