The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the cards for Montoya.

Alright, right off the bat, I gotta be straight with you – it’s gonna be a lean few weeks. There’s a big, quiet gap staring us down. We’ve got nothing worth paddling out for from now until Monday the 28th of September. That’s a long dry spell.

But if you’ve got patience, Monday the 28th is the one to circle. That morning at Montoya, the south-southeast swell will be pushing in at around 4ft. The combined wave energy will be moderate, sitting at (256), and the wind is set to be light and cross-offshore from the north at 6 mph, leaving the surface clean. The water temperature is a touch warmer than normal at 55°, so you won’t need the thickest suit. It’s a beach and point setup, so this south swell is right in its wheelhouse. Just a heads up, it’s a fairly consistent spot, so there should be enough waves to go around, but it can get crowded. For a spot that’s been flat for weeks, this morning window is the standout, no question.

Before that, there’s almost nothing. A few days like the 16th show 4ft of south swell (345), but the wind and conditions are too messy to recommend. Just sit tight.

After that Monday, the 29th of September Tuesday brings a bigger pulse – 5ft of south swell (591) – but it’s got a strong, choppy cross-onshore wind from the south at 12 mph, making it a messy, blown-out affair. That one is better left for the kites, not the paddle crew.

So in short: the first real surf window is Monday the 28th of September. Mark it down, and don’t bother before then.

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.
