The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming down the pipe for the Montoya area.
Right off the bat, don’t get too excited just yet. The first few days of August are looking flat and messy. Thursday the 6th has a tiny 1ft swell with almost no energy (42) and glassy conditions in the morning, but it’s just not enough to paddle out for. We’ve got a solid gap of poor to marginal conditions stretching from Thursday through the weekend and into the start of the following week. The wind is mostly cross or onshore, and the swell is either too small or too short-period to get excited about.
The first real standout I can see is shaping up for Saturday morning, August 8th. Montoya will see a 4ft SSE swell with a 11-second period – that’s a nice groundswell, and the water’s a touch warmer than normal at 55°. The wind is offshore from the NW at 12 mph, which will keep the surface clean. It’s not massive, but the energy is moderate (372) and the conditions are right for a fun session. Just be aware that crowds are possible here.
Now, if you’re an experienced surfer and you’ve got some patience, hang tight for Monday morning, August 17th. This is the real stand-out of the whole forecast. We’ve got a 8ft E swell rolling in with a 11-second period, packing a strong 1302 energy reading. The wind is offshore from the NW at only 9 mph, so it’ll be glassy and clean. The water temp is still a touch warmer than normal. This is a solid swell, and it’s pushing into the 8ft range, so it’s definitely for the more experienced crew. That said, the swell direction is from the east, and the optimum for Montoya is from the south, so it might not line up perfectly, but the quality and cleanliness should still make it worth the paddle.
Tuesday morning, August 19th, is another one to watch. A 6ft SSW swell with 9-second period, and the wind is light and glassy from the east at just 3 mph. The energy is moderate (644), and the conditions will be clean. It’s a solid option for a mid-week session.
The rest of the second week is mostly a write-off with onshore winds and poor conditions, so don’t bank on anything after that Monday stand-out unless you’re chasing wind swell.
Keep your eyes on that Monday August 17th session. It’s the one that’s got the most promise.
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.
