The Lowdown
G’day, Rusty here. Let’s check out what Montoya’s got in store over the next couple of weeks. Honestly, it’s a pretty quiet stretch, but there are a couple of moments that might get you out of bed.
The week starts off rough on Sunday the 13th. There’s a 5ft SSE swell, but with a 12 mph cross-on southerly wind, it’s choppy and messy – not worth suiting up. The water’s sitting at 55°F, which is a touch warmer than normal for this time of year, but that’s the only bright spot.
Monday the 14th is your first real chance. Early morning, the wind goes glassy with a light WNW breeze at just 3 mph. There’s a 2ft S swell with a 10-second period – nothing big, but clean and rideable. The combined swell energy is moderate at 167, so there’s a bit of push. It’s small, but if you’ve got a log, that glassy window is worth it. By afternoon, the wind shifts to a light SE offshore, but the conditions drop off.
Tuesday the 15th is a write-off. Morning has a strong 19 mph cross-off W wind, but the swell drops to a tiny 2ft from the east with a short 8-second period and weak energy (54). Afternoon gets a lumpy 4ft SW swell with a 5-second period and a 22 mph cross-shore wind – that’s a mess, and honestly looks more like kite-surfing territory than paddle surfing.
The rest of the week through to the weekend is pretty ordinary. Swell hangs around 1ft to 5ft, mostly from the SSE or S, but winds are generally cross-on or cross-off, and the periods are short – often under 9 seconds. The combined energy stays in the low to moderate range (48 to 339), but the “poor surf conditions” tag says it all. Thursday the 17th afternoon has a small clean 3ft SSE swell with light NNE cross-off winds, but it’s barely knee-high.
We hit a flat spell from about Saturday the 19th through to Monday the 21st. Swell drops to 0.7ft to 2ft with energy as low as 5 – barely a ripple. If you’re desperate, Monday the 21st has a 2ft E swell with a 9-second period and light cross-shore winds, but it’s not going to get the heart pumping.
Now, there’s a glimmer in the second week. Tuesday the 22nd sees a bump in swell – 5ft from the south in the afternoon, but it’s short-period (6 seconds) and cross-on, so it’s choppy. Wednesday the 23rd morning is the standout of the whole outlook. The wind goes light NNE cross-off at 6 mph, cleaning up a 4ft SSE swell with moderate energy at 178. The period is short at 7 seconds, so it’s not a groundswell, but those clean conditions make it the best bet of the fortnight. It’s only for intermediates and up at that size.
From there, the energy fades again. Thursday the 24th has a 4ft E swell in the afternoon with clean cross-off winds, but it’s ordinary. The rest of the second week through to the 28th is small, with swells under 3ft and mostly cross-on or cross-shore winds. Nothing else stands out.
So, overall: a flat and uninspiring run with one glassy morning on Monday the 14th for the small-wave crew, and a cleaner session on Wednesday the 23rd morning as the pick of the lot. Don’t hold your breath for the rest.
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.
