The Lowdown

Alright, folks, Rusty here. Let’s break down what we’ve got to work with for the next couple of weeks. It’s going to be a test of patience, that’s for sure, but there are a couple of bright spots if you play it right.

The forecast starts on a rough note. The winds are howling from the southwest, and while there’s some decent swell showing up, the conditions are going to be rough and blown out. Water temps are pretty normal for this time of year, so no surprises there.

The first few days are a wash. Big swells but with strong cross-offshore winds, it’s just going to be a mess. It’s not worth the fight.

Then, on Saturday morning, August 8th, the wind finally eases and turns offshore out of the northwest. The surf drops to a clean 4ft with a 11-second period. The energy reading is 372, which is moderate, but the clean conditions will make it feel better. This is a solid little window, especially if you can get out before the onshore breeze kicks up in the afternoon. Montoya will be a fun, clean wave.

From there, the ocean goes quiet. The swell turns to mush with short periods and onshore winds. The energy readings drop to double digits (104-97), which tells you there’s just nothing out there. For a week there, it’s just flat and grumpy.

Now, keep your eyes on the middle of the next week. On Tuesday, August 18th, the swell starts to build again, but the wind is still a problem, howling onshore from the east. It’s gonna be lumpy and closed out.

Wednesday, the 19th, is when the big one hits. We're talking a solid 13ft of swell with a 14-second period and an energy reading of 11521. That’s a huge, powerful swell. But the onshore wind is still strong, making it a giant, stormy mess. This is only for the most experienced and crazy hellmen out there. It’s more of a spectacle than a surf session.

The day after, Thursday the 20th, the swell backs down to a still-sizeable 7ft to 8ft, but the wind finally shifts to a clean, cross-offshore breeze from the west-southwest. This is the one to wait for. It’ll be much cleaner and more manageable than the day before, with a solid 12-second period. This will be a proper, powerful surf at Montoya. Definitely the pick of the week.

After that, the swell fades back down and the winds turn onshore again. It looks like we’re back to waiting for the next pulse.

So, to sum it up: you've got Saturday morning, August 8th, for a clean, small wave. Then you wait for the big one on Thursday, August 20th, which should be the standout. The 19th is a pass unless you’re a pro.

Rusty, out.

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.
