The Lowdown
Alright, Rusty here, checking in with the outlook for Long Reef.
It’s a bit of a slow start for the next few days, but there’s some real promise on the horizon if you’re patient. The first week or so is pretty quiet, with a run of small, weak surf and only a few windows that are worth a look. The water temp is sitting at 63°F, which is about a degree cooler than what’s normal for this time of year, so nothing to write home about there.
The first real standout is the morning of Thursday, September 10th. That’s the one to circle on your calendar. We’ve got a solid 10 ft S swell rolling in, with a period of 13 seconds, so it’s got some real groundswell grunt behind it. The combined energy is a massive 2904, which is seriously strong. Wind is a light NNW breeze, straight offshore, which will keep the waves clean and lined up. This is big, powerful stuff, so it’s really only for the experienced crew. Long Reef handles a S swell well, and with that offshore wind, it’s going to be a proper session. The morning of Wednesday, September 9th is also worth a look, with 8 ft S swell and a WSW offshore wind, giving you a taste of what’s coming, though the energy is a step down at 1625.
Between those highlights, there’s a lot of average to poor conditions. The mornings of September 4th and 6th have some small S swell around 4 ft, but the wind is onshore or cross, so it’ll be a bit messy. Thursday afternoon, September 10th drops off with a cross-onshore wind that chops things up. Then from the morning of September 12th right through to the end of the forecast, it’s a real desert. The swell drops right off, with heights under three feet, and the combined energy sinks into the weak zone. It’s a long quiet spell, and after the 13th, there’s nothing really rideable until the 16th, and even then it’s a tiny 2 ft NE windswell with hardly any energy.
So, to sum it up: the early stuff is a write-off, but Thursday the 10th is the clear winner for the experienced surfers. Get out there early for the best of it.
Rusty.

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