The Lowdown

Alright, listen up, crew. Rusty here. Let's talk about what's on the table for our local stretch. It's a bit of a mixed bag, and I'm not gonna lie, there's a lot of waiting involved. We're looking at a solid week of mostly flat, energy-sapped conditions before things finally get interesting.

First thing you need to know: the water's sitting at 54°F at Montoya, which is a touch warmer than normal for this time of year. That's a nice little bonus, but you'll be needing a suit for the rest of it.

Sunday, August 2nd, kicks off with a whimper. We've got a tiny 2ft south swell with a short, weak period of 6 seconds. The combined energy is a measly 34. That's nothing. The wind is a gentle cross-shore, but it's just not enough to make anything worth paddling out for. The whole week looks pretty grim—tiny swells, a lot of cross and cross-onshore winds. Monday the 3rd shows a little more energy (160) with a 3ft swell at 11 seconds, but the wave comment is still "poor." The pattern is basically the same through to the 7th: small, weak, and not worth your time. The best you'll see is some clean conditions on Friday the 7th, but that's from a 3ft, 4-second windswell—just no grunt to it.

Now, here's where it gets a bit more interesting, but also more dangerous. Saturday the 8th of August. The swell jumps up to 8ft from the WSW, but the period is still short at 6 seconds. The energy is moderate at 400. The wind is a strong cross-offshore, making it look clean. The problem? That's a lot of close-out, short-period dump. The swell pushes to 8ft in the afternoon with energy at 759. This is expert territory only. If you're a beginner, stay well away. This is a kite surfer's dream, not a paddle surfer's.

Sunday the 9th gets a bit more interesting. The morning shows a 5ft south swell with a long 12-second period and energy of 802. The wind is strong cross-offshore. The rating is still poor for the morning, but the afternoon brings a 8ft SW swell with massive energy (1059). That's borderline for most, and the short period (7 seconds) makes it a messy, powerful wall. Again, only for the experienced.

Monday the 10th of August is my pick of the whole forecast. We've got a 7ft SSW swell in the morning, a long period of 12 seconds, and a high energy of 1220. The wind is a fresh cross-offshore, making it clean. This is a proper groundswell. The long period will make the paddle-out easier, but it might break a bit straight at the beach. The afternoon drops to 5ft, which is more manageable, but still has that long 12-second period. The morning is the standout.

After the 10th, the energy drops off. Tuesday the 11th is a 4ft south swell at 12 seconds, but the wind is cross and light. The score is only a 1. The rest of the week goes back to small, choppy, and poor. There's a whole gap of nothing from the 12th through to the 17th.

Then, hold on. On Friday the 14th of August, we get a glass-off. The swell is tiny, 2ft, but with a long 12-second period from the SSE. The energy is still moderate at 284. The wind is glassy. This is the only day in the second week that looks clean, but it's small. The rest of the period from the 15th to the 17th is back to lumpy, onshore, or just poor conditions.

So, the bottom line: if you're a seasoned surfer, have Monday the 10th of August marked in your calendar. That's the best shot. For everyone else, it's a waiting game. The first week is a write-off, and the second week has only one day of glassy, small waves.

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.
