The Lowdown
G’day, Rusty here. Looking at the whole 16-day stretch, it’s a bit of a rough patch for Montoya. The start of the period is pretty lifeless, with tiny, weak surf and poor conditions. We’re looking at a few days of nothing much on offer before things get a little more interesting, but even then, it’s not exactly firing on all cylinders.
The first real standout doesn’t come until Saturday morning, August 8th. We’ve got a 4ft SE swell, but the kicker is the WNW offshore wind at 15 mph. That’s going to clean things right up. Combined energy is moderate at 226, and the period is a solid 10 seconds. It’s not huge, but it’s the best combination of rideable size and clean conditions we see in the near term. This is your window if you want a few fun ones without much drama.
Before that, Friday the 7th is a write-off. There’s a big 10ft S swell in the morning, but the SW cross-shore is howling at 25 mph, creating a messy, cross-chop. The afternoon drops to 7ft but the onshore wind is still fresh. It’s just not worth it. The swell energy is strong (1689 in the morning), but the quality is zero.
After that Saturday morning window, things go south again. The wind swings onshore and the swell drops off. The rest of the first week and into the second week is a story of poor surf and cross-onshore winds. There’s a period of bigger swell around the 11th and 12th, with 5ft SSE swells, but the onshore wind and short, choppy conditions make it a mess. The water temp is about average for this time of year, so no surprises there.
We get another tease on Sunday afternoon, August 16th. A 7ft SE swell with a WNW cross-offshore breeze at 9 mph. It’s clean and has some size, but the 7-second period is short and junky. It’s a marginal call, and the strong energy (504) is there, but the quality is questionable. The next morning, Monday the 17th, has 6ft SE swell but the WSW wind is blowing a strong 28 mph. That’s not for a paddle board, that’s more kite-surfing territory.
The final days of the forecast are small and weak. Tuesday the 18th has a little 3ft ESE swell with a light offshore wind, but it’s very ordinary. The period is short, and the energy is weak (133). It’s a grovel, but it’s clean. Honestly, the best bet in this whole run is that Saturday morning, August 8th. It’s not a classic, but it’s the only time the stars align for a decent, clean session. The rest is a waiting game.
Rusty out.

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.
