The Lowdown

Alright folks, Rusty here. Let’s talk about what’s coming up for Montoya. We’ve got a pretty quiet start to the outlook, so don’t be in a rush to grab your board just yet. The first week or so is looking pretty bleak, but there’s a glimmer of hope further out if you’re patient.

Things are flat and messy right out of the gate. The first few days are a write-off. Thursday the 30th of July kicks off with a weak 2ft S swell at 12 seconds, but it’s blown out by a cross-onshore wind. The combined energy is only 154, so it’s weak. The next few days through the weekend and into early next week are all no-go. Tiny waves, poor wind, and generally just not worth paddling out for. Lots of 1ft and 2ft bumps with the wrong wind directions. The water temp is about 54°F, which is a touch warmer than normal for this time of year, but that’s a small comfort when there’s nothing to ride.

We finally get a little flicker of life on Monday the 3rd of August. The morning is still marginal, but the afternoon brings a clean 3ft SSE swell at 11 seconds. The wind goes light and cross-offshore, making it tidy. The combined energy is moderate, sitting at 243. It’s not a standout, but it’s the first session that’s actually surfable.

The real action, if you can call it that, is buried in the second week. The best on offer looks like Monday the 10th of August. The morning is clean with a gentle offshore wind from the WNW and a 4ft SSE swell at 11 seconds. The combined energy is 315, so there’s a bit of push. It’s a beach and point setup, so that S-SSE swell direction is hitting the spot. This is a decent paddle for an intermediate surfer.

Following that, Tuesday the 11th of August is also worth a mention. The morning starts with a gentle offshore from the NW and a 3ft SSE swell at 12 seconds, with combined energy of 230. The afternoon is even cleaner with a light cross-offshore wind and the same swell, but the energy jumps to 339. The waves are clean and lined up, but it’s not huge.

The wave heights stay under 5ft for the whole period, so it’s not a problem for beginners. The swell periods are mostly in that 9-12 second range, giving you a decent shape without the long waits of a groundswell.

For the Monday the 10th session, the best of the best, expect a small but clean ride. The swell is from the SSE, which is the optimum direction for this spot. The gentle offshore wind means the faces will be smooth. It’s not a world-beater, but after a week of nothing, it’ll feel like a gift.

The rest of the second week fades into smaller, more ordinary conditions. There’s a bit of a bump on Wednesday the 12th, but it’s small and weak. The long-range stuff on the 13th and 14th of August is just not worth the drive, with poor wind and smaller, less energetic swells.

So, to sum it up: the first week is a total bust. The best chance to get wet is Monday the 10th of August, with Tuesday the 11th as a solid backup. It’s not a swell of the year, but it’s the cleanest, most consistent window we’ve got. Keep an eye on the forecast, but don’t hold your breath for the first few days.

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.
