The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Montoya over the next couple of weeks.
Right off the bat, I gotta be straight with you – the first few days are a write-off. Thursday the 6th and Friday the 7th are a total mess. Thursday has tiny, messy waves with poor conditions, and Friday brings a big, raw, 10ft southerly swell but it’s getting thrashed by strong cross-shore winds. That’s a no-go. The wait goes on right through the weekend, too. The swell is either too small, too short-period, or the wind is just junk. You’re looking at a solid gap of nothing worth paddling out for until we get to Saturday the 8th.
Now, Saturday morning the 8th is where we finally get a little window. The swell drops to a manageable 4ft from the SSE with a 10-second period, and the wind swings around to a light offshore from the NW. That’s clean. Combined swell energy is moderate at 339. It’s a small but workable day, and the offshore breeze will put some line in the face. For a beach and point set-up like Montoya, that’s your best bet in the near term. The water temp is about average for this time of year, so nothing wild there.
Monday the 10th and Tuesday the 11th see a bit more size, with 5ft to 6ft SSE swell, but the wind is cross or cross-on, ruining the shape. It’s lumpy and choppy. Not worth it.
The real standout, if you can wait for it, is Thursday the 13th in the morning. We’ve got a solid 5ft SSE groundswell with a very long 14-second period, and the combined energy is strong at 962. The wind is light and onshore from the SE, but that’s a bit of a bummer. Still, that long-period energy will push through, and if the tide lines up, the point at Montoya could handle the juice. This is the best quality swell of the whole period, but it’s not perfect. The long period means it’ll be a bit fat and straight on the beach, but the point section should offer some proper lines. This one’s promising, but it’s a week out, so keep an eye on the wind.
After that, the month of August runs out of steam. From the 14th onward, it’s mostly small, weak, and wind-affected. The 18th and 19th have some clean-ish cross-off wind but the swell is tiny – under 3ft. The 20th has a brief moment of 5ft ENE swell with clean wind, but the period is a short 6 seconds, so it’ll be weak and bumpy. Combined energy is only 168. For the last week, there’s not much to get excited about.
Overall, the best on offer is Saturday morning the 8th for a clean, small wave session, and the most promising swell is Thursday the 13th morning, if that light wind holds. Don’t hold your breath for the second week.
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.
