The Lowdown

Alright, this is Rusty, and I’ve got the long-range look for Montoya. It’s a bit of a mixed bag, so let’s get into it.

Straight up, the first week and a bit is a write-off for any decent waves. We’ve got a long, dry gap from now until the morning of Monday, September 7th with nothing worth paddling out for. The wind is messy, the swell is all over the place, and the conditions are just plain poor. You can forget about it.

The first real chance to get wet kicks off on Monday morning, September 7th. It’s not going to be a classic, but after a drought, you’ll take it. We’ve got a little 4ft groundswell rolling in from the SSE with a period of 9 seconds. The real story here is the wind: dead glassy with that ENE breeze at just 3 mph. It’ll be clean as a whistle. The combined swell energy is moderate at 257, so there’s some push. It’s surfable, but don’t expect any hero waves. That’s the highlight of the first week, but it’s a quiet one.

After that, it goes flat and ordinary again until we get to Sunday morning, September 13th. Now this is where it gets interesting. The swell jumps up to a solid 5ft from the S with a 10-second period, and the combined energy is strong at 465. The wind is a light offshore from the N at 6 mph, keeping it clean. This is the standout of the whole forecast for Montoya. It’s a beach and point setup, so with that SSE-optimum direction, it should line up alright. It’s going to be a good session, no doubt.

Now, Monday, September 14th has some action too. The morning is a bit rough with a cross-offshore breeze, but the afternoon cleans up nicely. You’re looking at a 5ft S swell at 9 seconds with a gentle N breeze, keeping it clean. That’s a solid secondary option if you missed Sunday.

The Tuesday morning, September 15th also offers a clean offshore wind, but the swell drops to 3ft from the S. It’ll be fun on a longboard, but it’s nothing to get too excited about.

Then we get a bit of a weird one on Wednesday, September 16th. The swell is small, around 3ft from the S, but the period stretches out to 12 seconds. That’s a proper long-period groundswell. It’ll have some energy (245 combined), but at a beach and point, that long period can make it a bit straight and tricky. The morning is clean with a light cross-offshore wind. It’s worth a look if you’re keen on a clean, if not powerful, wave.

Finally, the long-range outlook brings a big pulse on Thursday, September 17th. Swell jumps to 6ft from the SSE with a very long 15-second period, and the combined energy is a massive 1335. But the wind is howling from the SSW at 25 mph, making it a complete mess. This is only for the experts, and even then, it’s going to be a battle. Skip it.

The true standout here is Friday morning, September 18th. The swell drops back to a clean 4ft from the SSE, still with a very long 13-second period, and the combined energy is strong at 541. The wind goes glassy again, with an ESE breeze at just 3 mph. This will be the best-conditioned day of the entire run. Clean, lined-up, and powerful. Mark it in the calendar.

So, to wrap it up: the first week is a bust. The best on offer is Sunday, September 13th for the solid size and clean conditions, and Friday, September 18th for the glassy perfection. Don’t hold your breath for the rest.

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.
