The Lowdown
Alright, Rusty here, and I've been staring at the charts for the Monster Hole stretch. Gotta be straight with you – the next couple of weeks are a tough watch. The swell window is just not lining up for anything clean or with enough grunt. We've got a lot of small, weak, and messy days to wade through.
To start, the water temp is sitting at 84°, which is bang on average for this time of year, so at least the dip won't be a shock.
Looking at Wednesday the 16th and Thursday the 17th, we're dealing with a stiff 16 mph onshore breeze from the ENE. That's a no-go, with the swell sitting at a weak 5 ft to 5 ft but with awful short-period (6-8s) wind chop. The wave energy is weak to moderate at best, and it's just a lumpy mess.
Friday the 18th calms down a bit wind-wise with a lighter ENE breeze, but the swell drops straight away. We start the morning at 4 ft but that energy is already fading fast, and by the afternoon it's down to 3 ft and barely dribbling. The 19th and 20th are worse, with the swell shrinking to 2 ft and energy dropping into the pathetic range. We get a glassy morning on Sunday the 20th, but with 2 ft of weak NE windswell, there's just nothing to ride.
Monday the 21st is the same story – a tiny 1 ft wave with almost no energy. Honestly, it's a long, flat stretch.
Then we get a tiny glimmer on Tuesday the 22nd. The morning is looking glassy with a 3 ft wave from the ESE. It's only a 5-second period, so it’s gutless, and the energy is still weak, but at least it's clean enough to get wet. A few ankle-biters for the keen. The afternoon goes back to junk with a 12 mph cross-onshore wind ruining the 4 ft bump.
Wednesday the 23rd and Thursday the 24th are more of the same – small, weak swell (2 ft to 4 ft) and light to variable winds. The 24th has some clean glassy periods but the swell is tiny.
The best of a bad bunch might just be on Saturday the 26th. Morning is glassy again, with a 2 ft wave from the NE and the energy bumping up slightly. It's still described as "very ordinary," but it's the cleanest window we've had. Don't expect much.
We get a flare-up on Sunday the 27th afternoon – the swell jumps to 6 ft from the ESE, and the energy hits a solid moderate number. That's the most size we'll see, but it's being hammered by a 16 mph southerly cross-wind. It will be a messy, choppy mess, and with that short 6-second period, it's going to be a washing machine. Not worth it for a paddle, but with that kind of wind and size over a beach-and-reef setup, it might look more interesting for a kite surfer.
After that, it's back to the doldrums. The 28th, 29th, and 30th are all small, mostly messy, with the swell dropping back to under 2 ft and weak energy. We get a bit of clean air on the 30th morning and the 1st of October, but with waves barely reaching 2 ft, it's a flat spell.
Honestly, there's no standout window here. The 22nd and the 26th mornings are your only real chances to get a few glassy little waves, but they're tiny. The 27th afternoon has size but is blown out. It's a tough run.
Rusty.

Information about the Monster Hole Surf forecast
The above surf forecast table for Monster Hole provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Monster Hole can be found by selecting the local surf guide option on the grey menu. Our Monster Hole 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 (Monster Hole) 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 Monster Hole 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.
