The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s in store for us over the next couple of weeks. It’s a bit of a slow start, but we’ve got a couple of windows that are worth getting excited about.

We’re looking at a solid gap in the action for the first few days. The surf really doesn’t get going until Monday morning, the 7th, so you’ve got a few days to twiddle your thumbs. The first proper call is for that Monday morning.

Montoya is the only spot on the radar, and she’s a beach and point setup. The water is currently sitting at 55°, which is a touch warmer than normal for this time of year – nothing crazy, just a little bit of extra warmth in the water.

The first standout is shaping up for Monday morning, September 7th. We’ve got a clean 4 ft swell from the SSE with a period of 9 seconds. The wind is light and cross-offshore from the NNW, which means the waves will be clean and tidy. The combined wave energy is moderate (228). It’s a good, honest start to the week – not huge, but quality.

After that, the surf drops off hard. Tuesday and Wednesday are pretty ordinary with small, weak swells, so don’t get your hopes up. We go through a rough patch of poor conditions and strong onshore winds into the following weekend (September 12th and 13th). That weekend sees a big jump in size – Saturday afternoon hits 10 ft from the SSE (period 9 seconds, energy 1291), but it’s accompanied by a strong, cross-onshore breeze. That’s a beast of a wave, but it’s going to be a washing machine. The 8 ft+ range is strictly for experts only, and honestly, with that wind, it’s more of a kite-surfing setup than a paddle surf one.

The next real window of opportunity opens up on Monday morning, September 14th. The swell drops back to a manageable 4 ft from the east (period 8 seconds, energy 256), and the wind is light and cross-off from the NNE. It’s clean, it’s fun, and it’s a great morning to be out. Then Monday afternoon goes glassy – zero wind, 3 ft east swell, and absolutely perfect conditions for a cruisey session.

The real standout, though, the one you want to circle on your calendar, is Thursday morning, September 17th. North-west winds of 6 mph are blowing offshore, the swell is a solid 5 ft from the south with a good, long period of 11 seconds (energy 534). That’s groundswell, folks. It’s going to be clean, powerful, and well-shaped. The 5 ft mark is right on the edge of being too big for beginners, but for the intermediate and above crew, this is the pick of the forecast. The south swell is matching the optimum direction for the break, so it should be lining up nicely.

After that, the following weekend (September 19th) has a nice little morning session with a clean 3 ft swell from the SSE, but it’s a bit smaller. The long period (14 seconds) means it’s a groundswell, but it might be a bit straight for the beach break, so keep that in mind.

So, to wrap it up: the first week is a mixed bag with a decent Monday morning (7th) and a rough, stormy weekend. The second week has a proper highlight on Thursday the 17th. Don’t sleep on the Monday the 14th either, with that glassy afternoon. The rest is mostly small or blown out.

Stay stoked, and I’ll see you out there.

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.
