The Lowdown
Alright folks, it’s Rusty here, and I’ve been staring at the charts for Long Reef. It’s a bit of a mixed bag over the next couple of weeks, with some proper waiting periods, but there are a couple of sessions that are gonna be worth getting excited about.
Right now, around Thursday the 10th, we’ve got a solid 8 ft south swell rolling in, but the wind is howling from the south at 15 mph, making it a cross-shore mess. The energy is strong though, clocking in at 1256. It’s not the day for a clean paddle; the water is sitting at 64°, which is pretty much average for the time of year – nothing unusual there.
The real action starts to build for the weekend. Friday morning the 11th is looking much cleaner. The swell drops a touch to 6 ft from the south, but the wind swings light from the SSW at 6 mph, giving us a cross-offshore breeze. The wave energy is moderate at 660. It’s a solid window for a few waves.
But the standout, the one you’ve been waiting for, is Saturday morning the 12th. We’ve got 4 ft of south swell, but here’s the magic – the wind is glassy, dead calm from the northeast at just 3 mph. The period is a long 12 seconds, which is proper groundswell, meaning those waves will have some real shape and punch. The energy is moderate at 607. This is going to be clean, lined-up, and the best session of the near-term. Crowds can be an issue here sometimes, so get in early.
There’s a bit of a dry spell after that Saturday. The swell drops, and the wind gets messy for most of the next week. We’ve got a few days of small, choppy slop, nothing to write home about until the middle of the following week.
Now, for the long-range promise. Saturday the 19th is the big one on the horizon. The morning is looking excellent – a solid 10 ft swell from the south, with a clean offshore wind from the west at 9 mph. The combined energy is through the roof at 2310. That’s serious wave power. At that size, it’s for experienced surfers only, but the conditions are setting up for a proper session. The period is 11 seconds, so it’s got plenty of grunt. The afternoon holds at 8 ft with lighter offshore winds, still very good.
Then on Monday the 21st, we get another treat. The morning is glassy again, with 5 ft of south-east swell and zero wind. The energy is strong at 883. It’s a clean, calm start to the week.
Later in the week, Thursday the 24th afternoon shows a 8 ft north-east swell with a clean offshore wind from the west-northwest. That’s another promising call for the more experienced crew.
So, to wrap it up – the absolute best of the next two weeks are Saturday morning the 12th for the cleanest, glassy conditions, and Saturday morning the 19th for the biggest, most powerful swell with offshore wind. Mark your calendar for those two.
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.
