The Lowdown

Grab a coffee, 'cause the next couple of weeks at Montoya are looking like a story of almost-but-not-quite. We've got a promising little pulse early on, but then it gets messy before a quieter spell settles in. The water temp is about average for this time of year, so no shock to the system there.

Right off the bat, Tuesday morning the 8th is where you want to be. It's not a bomb, but it's the best we've got. That early session is seeing a clean, waist-high 3ft swell from the SSE with a period of 9 seconds. The wind is a light cross-offshore from the north, making for some clean lines. The combined energy is moderate at 147, so there's enough push to have some fun on a shortboard. It’s surfable but a little ordinary – not a classic, but a solid session for anyone itching for a paddle.

Things go downhill fast that afternoon as the wind swings onshore. The rest of that week and into the next is a write-off: tiny waves or 1ft to 2ft slop with poor winds and choppy conditions. There's a bit of a pulse of swell from the south on Saturday the 12th, with the swell jumping to 8ft to 8ft. The combined energy is strong at 835 to 981, so there's plenty of water moving. But the wind is howling from the south at 19 mph, making for a lumpy, cross-onshore mess. With that size and wind, it's really only for experts, and honestly, it looks more like a kite-surfing day than a paddle-surfing one. The conditions are just blown out.

We then hit a dry spell. From Sunday the 14th all the way through to Tuesday morning the 17th, there's barely a ripple worth mentioning. The swell drops to tiny 0.5ft to 2ft waves, mostly clean but with no power. It’s going to be a pretty flat and frustrating stretch.

Thursday morning the 17th offers a slight glimmer. We get a clean 3ft swell from the south, combined energy of 139, and a light cross-offshore breeze. It’s another "surfable but ordinary" day. Not a standout, but probably the best you'll see for a week. After that, we’re back into the doldrums with very small, weak swells and light winds right through to the 23rd. A couple of clean mornings on the 18th and 19th with 2ft to 3ft swells will be there for a log or a funboard, but there's no power or push behind them.

Honestly, for this stretch, the first Tuesday morning is your best bet. Everything else is either blown out or too small to get excited about. Stay tuned, though – forecasts can change.

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.
