The Lowdown
Alright, Rusty here again. We’ve got a 16-day outlook, but the first few days are total garbage. No surf worth talking about until Sunday the 13th, so that’s a four-day stretch of nothing. Once it kicks in, there’s a couple of bright spots, but you gotta be on it.
The only spot that matters is Reef. It’s an advanced reef break, exposed to the SW swell, and it’s fairly consistent when it’s working. Water temp is 68°, which is about average for this time of year, nothing crazy.
The whole start is a bust. Tuesday the 8th has a 4ft NW swell but with a 20 km/h cross-on wind, it’s choppy and ugly. Wednesday and Thursday are tiny and onshore. Friday the 11th is flat. Saturday the 12th is clean but only 2ft to 2ft – not enough.
Sunday the 13th morning is the real deal: a 4ft NW swell with a 13-second period and glassy conditions. Combined energy is 477 (moderate), no wind, and it’ll be clean. That’s a proper groundswell with long lulls, so paddling out is easier. The afternoon bumps to 4ft, but the wind goes NW cross-on, so the morning is where it’s at.
Monday the 14th morning is also solid: 4ft NW swell, 11-second period, light offshore cross-off breeze, and clean. Energy is 410 (moderate). It’s a similar wave to Sunday, just a touch smaller.
Then it fades. Tuesday the 15th is small and weak. Wednesday the 16th through Thursday the 17th sees a 3ft to 5ft NW swell, but the wind cranks up to 30-35 km/h cross-shore, making it lumpy and choppy. That 5ft on Thursday afternoon is only for experts, and with that wind, it’s a mess.
The second week is mostly flat. From Friday the 18th to Sunday the 20th, it’s tiny – 0.3ft SW swell, no energy. Monday the 21st has a 3ft NW swell, but the wind is cross-shore again. The last chance is Wednesday the 23rd morning: 2ft NW swell, glassy, clean, but it’s just a small, quiet wave.
So, your two best bets are Sunday the 13th morning and Monday the 14th morning at Reef. Sunday has the best combo of size, glass, and that long-period groundswell. Monday is a close second. The rest is either flat, windy, or not worth it. The break is fairly consistent, so a few days of nothing is normal around here. Keep an eye on that Wednesday the 23rd, but it’s a long way off.
Stay stoked.

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