The Lowdown
Alright, Rusty here again. Let’s see what Montoya has cookin’ over the next sixteen days, in feet and miles per hour.
Right out the gate, Saturday the 22nd has clean-looking 5ft waves from the S, but that cross-off breeze at 19 mph will keep things a bit bumpy. Water temp is about 51°F, which is normal for this time of year – nothing wild. Sunday the 23rd jumps up to 8ft from the S, but the wind’s still messy, cross, and that swell has some serious welly behind it (combined energy of 2419). That’s long-period groundswell at 13-14 seconds, and at 8ft it’s expert-only territory. Monday the 24th is the real gem – glassy, dead calm in the morning, 6ft S swell, 12-second period, combined energy of 931. That’s your cleanest, most user-friendly day of the whole forecast. The wind direction is offshore, which is ideal. Crowds can show up here, so be sharp.
After Monday, it drops off fast. Tuesday the 25th is down to 4ft and cross-wind, just so-so. From Wednesday the 26th right through to Thursday the 3rd of September, it’s a long, flat, boring stretch. Swell tiny, winds mostly onshore or cross-on, combined energy often under 100. Nothing worth chasing.
There’s a tiny spark on Sunday the 6th of September – glassy again in the morning with a 5ft E swell and combined energy of 260. Clean surface, but it’s a long way out. Worth a peek but don’t rearrange your life for it.
So the one to circle is Monday the 24th. Get in early, score the cleanest waves of the whole outlook. After that, you’re waitin’ nearly two weeks.
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.
