The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Montoya over the next couple of weeks.
First up, the outlook isn't great. We've got a few days of poor to marginal conditions before a brief window of cleaner surf, then it drops away again. The water temp is about average for the time of year at 52°F.
The early part of the run, starting Sunday the 23rd, is pretty average. We've got a solid 8ft S swell with a 13-second period pushing in, but the wind is a cross-on 16 mph from the SSW, which is going to make it choppy and messy. The combined swell energy is strong at 2084, but the quality is just not there. Sunday afternoon drops to 7ft but the wind stays cross, so it's still not great.
Monday the 24th sees the swell drop to 6ft from the SSE with a 12-second period, and the wind swings more onshore at 9 mph from the S, so it's still choppy. Monday afternoon the wind goes light onshore from the SSE, but it's still marginal.
Tuesday the 25th is small – 4ft from the SSE with 11-second period – and the wind is light cross from the NE, so not much to get excited about. The energy is weak at 382.
Now, Wednesday the 26th is where we get a bit of hope. The swell is a clean 5ft from the SE with a long 14-second period, and the wind is a light cross-off from the NNE, keeping the surface clean. This is your best bet in the first week. The energy is moderate at 802, and with the offshore wind, it’s going to be well-shaped. It's not huge, but it's clean. Wednesday afternoon stays clean but the wind picks up a bit.
Thursday the 27th drops off to under 3ft, and the wind goes cross, so it's back to marginal.
From Friday the 28th, it gets poor again. Swell drops to 2ft with onshore wind, and it stays that way through the weekend. The energy is weak, under 100.
Monday the 1st of September sees a slight pulse of 5ft from the ESE with a 10-second period and cross-off wind, so it's clean but still small.
Wednesday the 3rd of September has a small 4ft swell from the SSE with a short 8-second period, but the wind is light offshore from the NW, so it's clean. The energy is weak at 314. It's surfable but nothing special.
After that, the swell fades into nothing. By the 5th and 6th of September, we're looking at under 3ft with no real energy. The second week is a write-off.
The standout is Wednesday the 26th of August. It's not big, but it's the cleanest wave of the period with a long-period SE groundswell and light cross-off wind. Montoya is a beach and point setup, and with that long period, the point will hold it better than the beach. You'll want to be there early.
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.
