The Lowdown
Alright, this is Rusty. Let me check the charts for Montoya.
We’re looking at a pretty tough stretch ahead for Montoya. The first real chance of any surf isn’t until Monday the 24th, so there’s a gap of a few days before anything worth paddling out for.
Right now, through this weekend, it’s a write-off with fresh cross-onshore winds and lumpy, poor surf.
Monday the 24th is the standout. Montoya is a beach and point set-up. The morning brings a clean, glassy 6ft SSE swell with long 13-second periods. The water temp is 51°, which is about average for this time of year. The wave energy is moderate (1009), and this is great for anyone with a bit of experience. This is the best on offer.
Tuesday the 25th is still clean with offshore cross-off winds from the NNE. The swell drops a tad to 4ft from the SSE, but the 11-second period keeps some shape. Decent option for a quieter session.
Wednesday the 26th afternoon looks promising with a clean, cross-off wind and a 4ft SE swell. The period stretches to 14 seconds, which means some real groundswell energy, making it a nice option for a late afternoon paddle.
From the 27th onward, the swell fades out and the wind turns messy. The energy drops right off, and we see weak, short-period windswell (energy values of 60). It gets blown out and choppy.
September 2nd and 3rd are a long-range hope. Swell picks up again with offshore winds. Wednesday the 2nd afternoon has a clean 7ft SSE swell with a moderate offshore breeze – that’s a solid expert-level wave. Then Thursday the 3rd afternoon sees a clean 7ft SE swell with 12-second periods and light winds. The wave energy is strong (1169). This is promising, but it's over a week away, so treat it as a good sign rather than a guarantee.
After that, the onshores return and the quality slides again.
So, if you can wait, the cleanest and most powerful window is Monday the 24th morning, and the long-range bet is on Thursday the 3rd of September afternoon.
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.
