The Lowdown
Alright, Rusty here, let's take a look at what’s coming our way for Montoya over the next couple of weeks.
Well fair dinkum, it’s a pretty quiet and drawn-out run of small, wind-affected surf for Montoya. We’re looking at some real skinny pickings, and honestly, there isn’t a single standout day where everything clicks. The closest we get to something half decent is the start of next week, but even that comes with caveats.
The pattern sets in right from the get-go. This Sunday the 6th is a write-off – onshore winds out of the south at 16 mph, that 7 ft of south swell is messy and blown out, with moderate wave energy (717). It doesn't get much better through that first week. Monday morning the 7th is the only real glimmer in this whole outlook. The wind goes light and offshore from the NNW, cleaning up a small 4 ft south-southeast groundswell. The combined swell energy is moderate (228), and the clean conditions make it the best of a very average bunch. It’s a long-period swell too, with a 9-second interval, so the sets will have some push for a point break setup. Keep an eye on the crowds though – it’s likely to be a popular choice for anyone local.
The rest of that week is small or onshore. Tuesday the 8th sees a drop to 3 ft, and then Wednesday the 9th is almost flat with just 1 ft. The water temp anomaly isn't mentioned here, so I’d say it’s about average for this time of year.
We then hit a long, frustrating stretch from the 10th through to the 16th. The swell gets a nudge from the east and southeast, but the wind is just terrible – cross-on and onshore, howling out of the east and southeast. On Saturday the 12th, a big 10 ft swell arrives from the ESE, but it’s accompanied by a near gale. That energy is strong (1238), but with wind like that, it’s just a washing machine. That’s expert-only, and even then, marginal. The following days stay messy with strong cross-onshores. The whole setup looks more appealing for kite surfing than paddling into a wave.
Around Monday the 14th, the swell drops back to a manageable 5 ft from the east, and the wind goes light from the ENE, but the direction is cross-shore. The combined energy (735) is moderate, but it’s still considered marginal surf. Conditions are cleaner, but not great.
The second week offers just about nothing. From the 16th onward, it’s small and onshore from the south, with very weak energy readings. By the 19th of September, we’re looking at tiny 1 ft swell with very low energy (42). The run of poor surf looks pretty cemented in.
If you’re itching for a paddle, your one and only window is Monday morning, the 7th of September. Get in early for clean, glassy conditions on that small but clean groundswell. Any other day, you’re better off waxing your kite board or just taking a break.
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.
