The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the table for the coming weeks.
Right off the bat, we’ve got a bit of a waiting game. The early part of the outlook is a mixed bag, with a lot of poor surf conditions and questionable tides. The first real chance to get wet isn’t until Saturday morning, August 8th, after a bit of a slow start.
The standout window is shaping up to be Tuesday, August 19th, through Thursday, August 20th. That’s where the real potential lies. For the experienced crew, Thursday, August 20th, is the one to circle. The northwest offshore wind will be light, from 6 to 9 mph, and we’re looking at a solid 7 ft to 7 ft swell from the ESE. That’s over 8 ft on the peak, so this is strictly for experts – the power is real. The combined wave energy is massive, hitting 1247 on Thursday morning, so you’ll feel it. The period is a very long 12 seconds, which is groundswell, and at Montoya (a beach and point set-up), it might be a bit straight for the beach, but the point should handle it beautifully. The wind is clean and offshore, so the surface will be glassy. The water is sitting at 54°, which is a touch warmer than normal for this time of year, so don’t be afraid of a shorty.
The preceding days, Tuesday, August 19th, also have some juice, with 8 ft ESE swell and cross-off winds, but the forecasts are a bit more marginal. Still, if you’re keen, there’s a wave there.
For the rest of the period, it’s a lot of cross-onshore wind and messy conditions. There’s a brief window on Monday, August 17th, in the afternoon when the wind swings to a light westerly cross-off, and we get a 6 ft swell from the east. It’s a short period, though, so don’t expect much power. The combined energy is only 298, so it’s weak. It’s a salvageable session if you’re desperate.
Before that, the first week is mostly a struggle. The morning of Saturday, August 8th, has a nice 4 ft SSE groundswell with a perfect offshore wind from the NW, but it’s a one-off. The rest of that week is plagued by strong cross-off winds and poor quality surf. The swell is present, but the wind is just ruining it.
The long-range stuff around August 21st and 22nd looks like it fades into small, weak, onshore mush. The energy drops off a cliff, down to 181. Not worth the paddle.
So, bottom line: if you’re an expert, Thursday, August 20th, is the clear winner. Clean, powerful, and offshore. For everyone else, wait and see if the forecasts clean up the weekend of the 17th. Otherwise, it’s a waiting game.
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.
