The Lowdown

Alright, Rusty here again, talking in feet and Fahrenheit.

We’ve got a bit of a slow start, with nothing worth paddling out for right away. The first real glimmer comes on Monday morning, September 7th, at Montoya. It’s a beach and point setup that’s fairly consistent, and the morning shows some clouds with a light offshore NNW breeze at 6 mph. The swell is a clean 4 ft from the SSE with a period of 9 seconds. The water temp is about average for this time of year. That morning window is the standout early on—clean waves with moderate energy, and it’s a classic dawn patrol call. Crowds are possible, so don’t expect solitude.

Tuesday morning, the 8th, drops to 3 ft from the SSE, still clean with a light cross-offshore N wind at 6 mph. It’s smaller, but still surfable.

The afternoon of Thursday the 10th sees flat, glassy conditions on Thursday morning with a tiny 1 ft SSE swell, but the window for decent surf narrows quickly. Friday the 11th turns ugly with onshore wind and building chop from an Easterly wind, and the swell turns short and messy. Then Saturday the 12th brings a solid spike—8 ft to 10 ft swell from the SE, with a period of 8-9 seconds. But the onshore wind cranks at 22 mph, and there’s strong to very strong wave energy. That’s expert-only territory—kite surfing material more than paddle surfing.

After that, the 13th holds a 6 ft swell from the ESE on Sunday morning, but it’s onshore with strong energy, and it’s only marginal.

The real standout in the second week? Look to Monday morning, September 14th. Montoya cleans right up with a light offshore N wind at 6 mph, a nice 3 ft ESE groundswell at 10 seconds. The energy is moderate, and the wind is cross-offshore, so expect clean, lined-up waves. That’s a proper session.

Then there’s a longer gap until Thursday the 17th, when a much bigger pulse arrives overnight. Thursday morning has a clean, offshore NW breeze at 3 mph, and the swell jumps to 6 ft from the S with a very long period of 12 seconds. That’s groundswell, strong to very strong energy—experts will love it. The point break handling those long-period waves will be the call. That’s a promising but less certain call at this range.

After that, the surf fades again through the 20th and 21st, with small, clean but weak leftover pulses.

So, overall, your best windows: Monday morning the 7th for a clean, moderate SSE swell, and Monday morning the 14th for clean, glassy conditions on a small but nice groundswell. If you want more size, the 17th morning is worth circling, but it’s a long-range gamble.

Stay sharp.

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.
