The Lowdown
G’day, Rusty here. Lookin’ at Montoya, and it’s a lean stretch overall. First few days? Forget it. Tiny, sloppy, nothing doing.
Your first sniff of something surfable comes Monday morning September 14th. Waves about 3ft from the SSE, 11-second period—that’s a long period groundswell with moderate energy (170). Wind’s light offshore from the northeast, so it’s clean. Surfable but nothing special. Water temp’s about 55°F, just a touch warmer than average.
Tuesday the 15th tries to pick up: 4ft from the SW in the morning, but period’s only 5 seconds—weak and short. Afternoon jumps to 8ft from the S, 8-second period, energy strong at 896, but cross-shore wind makes it a chop fest. Better for kite boardin’.
The real standout? Wednesday September 16th. Swell runs 7ft from the SSE with a 12-second period, combined energy way up at 1294 (very strong). Winds are light cross-on, so not glassy but plenty of power. Big enough that only experienced surfers should paddle out. Wednesday afternoon’s still 6ft, same direction, still decent.
Thursday the 17th holds 5ft from SSE with 11-second period (moderate energy 451), clean offshore from the north. Good day for a session.
Then it fades. Under 3ft for days, with occasional offshore breezes but not enough wave to make ‘em count. Next little pulse comes Monday the 21st: 5ft from SSE, but period’s just 6 seconds, sloppy again.
So if you’ve got the skill, Wednesday September 16th at Montoya (beach and point) is the pick. Big swell (7ft), long period (12 seconds), proper energy. Not perfect wind, but the size and power do the talkin’. Beginners, stay outta the water that day. Most other days? Grab a coffee, wait it out.

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.
