The Lowdown
Alright, let’s be straight. The next 16 days at Montoya start off rough. From July 27th all the way through August 10th, it’s a long, dry spell of poor surf. That’s a big gap with nothing worth talking about.
Swell is tiny, wind is from the wrong directions, and the water is choppy or blown out. Even when the energy picks up a little around July 31st and August 1st (moderate energy in the 142 to 205 range), the wind and chop kill it. Not worth your time.
Then, on August 5th, things get a little better. Morning brings a light cross-offshore wind from the north-northeast, with waves around 4ft from the southeast, period of 9 seconds. Energy is 182 (moderate). It’s clean, but only just surfable. Nothing special.
The real standout hits on August 11th and 12th. Tuesday morning, August 11th, is glassy – no wind, totally clean. The swell is 3ft to 4ft from the south, with a long period of 13 seconds. That’s groundswell, packing a punch. Combined energy is 403 (strong wave energy). This is the best looking setup of the whole forecast. The long period will make the waves well-shaped and powerful, but the sets will be spread out, so it’s easier to get out the back. The water temp is 53°F, which is about normal for this time of year. Tuesday afternoon holds with 4ft south swell at 12 seconds, energy at 384. Crowds are possible, so plan around it.
After that, it fades fast. So mark your calendar for that Tuesday. That’s the one.

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.
