The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking at Montoya. I’ve got to be straight with you – the next 16 days are a real mixed bag. We’ve got a big pulse of energy coming through, but it’s tricky to find a clean window. The water temp is sitting about average for the time of year, nothing to write home about.
We kick off with nothing doing. Tuesday the 4th through to Thursday the 7th of August is mostly a write-off. Small, weak, and messy. The wind is on it or cross-shore, and the wave energy is pitiful. Thursday the 6th sees a bit of a cross-off breeze, but the swell is only 1ft from the SSE – not enough to get excited about. You’re looking at a gap of several days with no real surf.
Then, hold onto your board. Friday the 7th of August morning, the ocean wakes up. A big 12ft SSW swell rolls in, with a strong breeze from the WSW keeping it clean. The combined energy is pumping at 3328 – that’s serious power. But here’s the catch: that’s a lot of water moving. For the average punter, this is too big. This is expert-only territory. The swell period is 11 seconds, so it’s got some proper groundswell grunt. The afternoon drops to 8ft from the S, still clean, but conditions are only marginal. This is the standout window, but it’s not for the faint-hearted.
Saturday the 8th of August morning is your best bet if you’re not a charger. We get a clean 4ft SSE swell, with a lovely offshore NW breeze at 12 mph. The energy is a solid 443, and the morning is showing "expect good surf conditions." That’s the sweet spot. The wind is offshore, so it’ll be glassy and clean. The afternoon, however, gets chopped up by a fresh cross-off wind.
Sunday the 9th of August has a 6ft swell from the SW, but it’s short-period windswell at only 6 seconds. That means bumpy, weak waves. The wind is cross-off, so it’s clean but the quality is poor.
After that, things go quiet again. From Monday the 10th through to Tuesday the 19th of August, it’s mostly small, onshore, and poor. The only tiny flicker is on the 18th of August, Tuesday afternoon, when the wind goes glassy with a 3ft S swell. The energy is a meagre 109, and the comment says "surfable but very ordinary." That’s the definition of a skunk session.
So, to wrap it up: if you’re an expert, Friday the 7th of August morning is the big one – massive, clean, and powerful. For everyone else, Saturday the 8th of August morning with the offshore wind and 4ft swell is your best shot. The rest of the fortnight is a dud. Keep an eye on the charts, but honestly, don’t hold your breath.
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.
