The Lowdown
Alright folks, Rusty here with a look at what's cookin' at Montoya over the next couple of weeks. Gotta be straight with you, it's a bit of a slow burner. There's a decent little window early on, but then we're in for a long, quiet spell.
The action starts this Sunday morning, the 16th of August. Montoya is a beach and point setup, and it's exposed to the south. It's a fairly consistent break, so you can usually bank on something. For the early session, we've got a clean 4ft easterly swell pushing in. The wind is a light, cross-off breeze from the NNE, which is gonna keep things looking tidy. The water's sitting at 53°, which is pretty much bang on average for this time of year. The combined energy is moderate at 209, but with that clean surface, it'll be worth a paddle. Just a heads up, this spot can get busy sometimes, so you might have some company.
From Sunday afternoon onwards, it's a long road. The wind swings around and the rain sets in. By Monday and Tuesday, the onshore wind is howling from the southeast, ruining any shape. We get a bit of size on the 20th of August with 6ft, but it's cross-onshore and choppy. Not what you want. The following days are a write-off. We're talking day after day of onshore, cross-shore, and strong breezes. A big 8ft south swell arrives on Sunday the 23rd, but the wind is a mess, creating a lot of chop. That combo of a bigger swell and strong wind on a beach setup makes it look more interesting for the kite surfers than for us paddle surfers.
This dry spell runs all the way from Sunday afternoon through to the end of the month. The only flicker of hope comes on Monday the 25th of August. The morning shows a 3ft south swell with a clean, cross-off breeze from the NNE. The combined energy is a moderate 217, and the surface will be glassy. It's a solid little session for the early birds after a long wait, but it's a one-off.
The very end of the forecast, Monday the 31st of August, shows a 5ft southeast groundswell with a period of 13 seconds. That's a lot of energy (825), but it's coming in on a cross-shore wind which will muss it up. It's a tease of what could be, but for now, it's a waiting game.
The best bet? Hands down, it's Sunday morning the 16th. Get in the water early. The second standout is the Monday morning the 25th, but it's a slim window after a long drought. For the rest, it's a case of watching the forecast.
Stay patient.
Rusty.

A general guide to surfing at Montoya can be found by selecting the local surf guide option on the grey menu.

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.
