The Lowdown

Alright folks, Rusty here. Let's be straight with you, it's been a bit of a quiet stretch and the next couple of weeks look like a mixed bag. There's no massive swell on the horizon, but there are a few windows where we can get a decent wave if we're patient.

The first real chance to get wet is Tuesday, August 25th at Montoya. We're looking at a 4ft SSE swell, with a period of 11 seconds, so it'll have some push. The combined energy is sitting at 382, so it's a moderate pulse. The wind is a light cross-shore from the NE at 6 mph, so it won't be glassy, but it'll be surfable. Water temp is pretty standard for this time of year, nothing out of the ordinary. Don't expect perfection, but it's a start.

The best call for a proper surf is hands-down Thursday morning, August 27th. The swell drops back to a clean 3ft from the SE, but it’s packing a 13-second period, so that's some nice groundswell. The standout feature here is the wind: a light NW offshore at 6 mph. That's going to make it clean and lined up. The energy is moderate (394). This is the window to leave the office early and go get some head-high waves. Later that afternoon the wind shifts onshore and kills it.

Monday, August 31st morning is another one to keep in the back of your mind. The swell is 4ft from the east, but the period is only 7 seconds. Still, we get a light W cross-off wind that will keep the surface clean. The energy is low (156), so it'll be weaker, but it's a surfable option if you're desperate.

Beyond that, the surf tries to kick again around Tuesday, August 25th with a 5ft SE swell on the 26th, but that's accompanied by a moderate 12 mph cross-shore wind that will chop things up, so it'll be a battle. The big swell on the 26th (5ft, 1115 energy) is there, but with the wind being average, it’s not really worth the drive for most.

Later in the period, around Thursday, September 3rd, there's a spike of 4ft to 5ft SSW windswell, but the wind is howling at 19-25 mph, making it a proper mess. That one is more of a kite-surfing show than a paddling session. Same story on Friday the 4th with 4-4ft from the south and strong onshore winds.

For the second week, things get pretty flat. From about September 5th, it's small and choppy. There's a small window on Saturday, September 5th afternoon with a 3ft SSE swell and a 13-second period, but the wind is cross-shore, so it'll be average. After that, it's very small and weak until the end of the forecast, with only small, weak pulses from the east.

So, to recap: Thursday the 27th morning is your standout. Best combo of clean conditions and a nice long-period swell. The 31st morning is a strong second option for a clean wave. The rest, you'll be chasing scraps. It's not a classic run, but there are a couple of golden moments if you time it right.

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.
