The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for our local stretch, Montoya. Gotta be straight with you – it’s a bit of a lean run ahead, so don’t get your hopes up too high.
The next couple of days are where the only real action is. Tuesday morning, 25th August, is your best bet. We’ve got a clean 4ft swell rolling in from the SSE with a solid 11-second period, pushing moderate wave energy (382). The water is sitting at 52°, which is bang on average for this time of year, so nothing weird going on there. With a light NNE cross-off breeze, it’ll be glassy. This is the standout – but keep in mind, it can get a bit busy here, so expect some company in the water.
Wednesday morning, 26th August, sees the swell jump up to 5ft from the SE, with a very long period of 15 seconds. That’s a lot of energy (1112). Sounds good, but a strong NE cross-shore wind is going to mess it up with chop. It’s on the bigger side, so maybe more for the experienced crew, but the quality is marginal at best.
After that, things go flat and quiet. From Thursday afternoon right through to the end of the forecast period, we’re looking at dribbly little waves, poor winds, and onshore slop. There’s a solid gap of over a week with nothing worth paddling out for. There are a couple of mornings with clean conditions and glassy water, like Tuesday 1st September and Sunday 6th September, but the swell is tiny – 2ft and 1.0ft – just not enough to get excited about.
So, to sum it up: get out there Tuesday morning, 25th August, if you can. It’s the only real window we’ve got. The rest is a waiting game.
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.
