The Lowdown
Alright, this is Rusty. Let’s cut through it. I’ve looked over the whole 16-day run for Montoya, and I’ve got to be straight with you—it’s a tough stretch. There are no proper standouts here, no day where everything clicks into place for a proper session. The whole period is basically a string of poor conditions, with only a few brief, ordinary windows.
We start off with a real dud. Thursday the 13th through to the end of the following week has almost nothing going for it. For the first nine days, the surf is either too messy, too choppy, or the wind is just blowing all over it. The combined wave energy on Thursday afternoon is moderate at best (513), but the wind is a cross-onshore mess, ruining any chance of a clean face. Swell direction is mainly from the SSE or E, which isn’t lining up well with the optimum S direction for Montoya.
The only real glimpse of something half-decent comes on Sunday morning, the 16th. The wind drops to glassy (5 km/h from the NNE), and the swell is 4ft from the E at 8 seconds. The combined energy is low (190), and the report itself calls it “surfable waves but very ordinary conditions.” It’s nothing to write home about, but if you’re desperate, that’s your best window in the first week. Just know it won’t be anything special.
After that, it’s back to poor surf and onshore or cross-onshore winds for days. By Tuesday the 20th, things actually get a bit nasty—a strong breeze from the SSE hits 45 km/h, pushing 8ft swell onshore and turning it into a messy, blown-out wall. That’s expert-only territory at best, and honestly, it looks more interesting for kite surfing than paddling.
There’s a brief clean-up on Friday the 21st with light offshore winds (WNW at 30 km/h) and clean conditions, but the swell is tiny—only 3ft. For a point break setup like Montoya, that’s barely dribbling.
Moving into the second week, the pattern doesn’t improve much. There’s a slight bump in energy on Wednesday the 26th—combined energy hits 1167 (strong) with a 4ft swell from the SE at a very long 16 seconds. That’s groundswell, and it could make for some clean lines if the wind cooperates, but it’s a cross-shore breeze and the direction isn’t ideal for Montoya’s optimum S exposure. It’s a tease.
The only other moment worth a mention is Thursday morning the 27th: 4ft from the SE at 13 seconds, with light cross-shore winds from the NE at only 10 km/h. Combined energy is moderate (539), but the real issue is the swell direction—it’s not hitting the spot properly. Still, if you’re a local who knows the banks, you might find a corner that works.
Bottom line: there’s no day in this 16-day window that I’d call a winner. If you’re sitting on the fence, don’t bother waxing up until you see a proper change in the charts. Forecasts can always shift, but as it stands, Montoya is giving us nothing to get excited about.

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.
