The Lowdown

Alright folks, Rusty here, checkin' in from the coast. Let's get into it. We've got a 16-day window for Montoya, and I gotta be straight with you—it's a tough one. The whole run is a struggle, with very few moments that even come close to being worth a paddle. We're looking at a long, quiet stretch broken up by a couple of days of messy, powerful swell that just can't get its act together.

The first few days, from Tuesday the 18th right through to Thursday the 21st, are a write-off. We're talking small, weak, onshore slop. Not worth even checking the cam. The wave height is barely 2 ft, and the wind is just ruining anything that might try to stand up.

Then things get a bit weird. From Friday the 21st through to Sunday the 23rd, the swell actually starts to pump in. We're seeing chest to head-high sets, up to 6 ft, with the swell energy jumping into the strong range. But here's the rub: the wind is a nightmare. It's a strong, fresh cross-shore, creating lumpy, choppy conditions. The swell period is short and weak at first, barely 6 seconds, building to a more promising 13 seconds by Sunday. The water temp is sitting at 52°F, which is about average for this time of year, so nothing wild there.

Even when the wind does a bit of a favour on Saturday afternoon the 22nd, turning clean for a session with a 6 ft SSW swell and a 9-second period, the waves are still a mess. It's a "marginal" call. It's the closest we get to a highlight, but it's not one I'd be racing for. The setup is a beach and point, so with that much wind and messy swell, it honestly looks more interesting for a kite surfer than a paddler.

From Monday the 24th onwards, it's a slow fade back into small, weak, and mostly average conditions. The swell drops back below 3 ft, the energy fades, and the wind is a mixed bag of light cross-shore breezes. There's a glimpse of something clean on Tuesday morning the 25th with a 3 ft SSE swell and a cross-offshore breeze, but it's still a poor call. The best of the small stuff is Wednesday the 26th, with a 2 ft SSE swell and offshore winds going glassy—that's a rare moment of peace. But it's tiny, and it doesn't last.

Honestly, there's no standout session here. The whole forecast is a battle between getting some size and getting any quality. If you're desperate, keep an eye on Saturday afternoon the 22nd for the cleanest, most powerful-looking slop, but don't expect much. The rest is a waiting game. Forecasts can change, but right now, this is a long, blank run for Montoya.

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.
