The Lowdown
Alright, Rusty here again. Let’s break down the 16-day outlook for Montoya. It’s a rough start, with a long gap of flat, poor conditions. The water temp is about 53°F, a touch warmer than usual for this time of year, so it’s not too bad.
The first real chance to get wet is Saturday morning, August 1st. A light offshore breeze from the WNW cleans up a 3ft east swell, period around 9 seconds. The energy is moderate (177). It’s surfable, but it’s small and ordinary. That afternoon, the wind swings and ruins it.
From there, we hit a dead zone. Days of cross-onshore wind and weak swells. The energy is low, and the wind is always wrong. The surf is poor.
The real standout is Monday afternoon, August 10th. The wind goes glassy, dead calm, with a 4ft SSE swell and a long period of 12 seconds. The energy is strong (400). That’s proper groundswell, and with glassy conditions, Montoya will be clean and lined up. The long period means the sets will be spaced out, making it easier to paddle out, but it might be a bit straight on the beach. This is the best session of the whole forecast.
The morning of the 10th is also worth a look with a 3ft SSE swell and a light cross-shore breeze (372 energy), but it’s not as clean.
After that, Tuesday the 11th of August brings a bigger 5ft SSE swell (578 energy), but the wind is cross-shore and choppy, making it a messy, lumpy mess. The rest of the week fades back into small, cross-onshore junk.
So, for the whole 16 days, the one to circle on your calendar is that glassy Monday afternoon on the 10th of August. Everything else is a write-off. If you’re a beginner, the swell only tops 5ft on the 11th, but it’s messy, so it’s not great. For experts, the 5ft day on the 11th has the size, but the wind kills it. Keep an eye on that 10th, though.
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.
