The Lowdown
Alright, let’s have a look at what’s coming up for Reef over the next couple of weeks. I’ll be straight with you – it’s a pretty flat, quiet run. There’s nothing here that’s going to get the heart pumping, and honestly, not a single standout in the whole 16-day window. Let’s walk through it.
The first few days are weak. On Sunday the 2nd, we’ve got a tiny 2 ft swell from the west, period around 9 seconds. Combined energy is sitting at only 110 – that’s weak. Winds are a cross-shore from the NNW at 9 mph, so there’s a bit of lump on it. It’s not doing much. Monday the 3rd sees the swell staying at 2 ft to 3 ft from the west, but cross-onshore winds pick up to 12 mph in the afternoon, making it choppy. Energy drops to 130. Not a recommendation here.
Tuesday the 4th brings a little change – cleaner sky, wind goes onshore from the west at 6 to 9 mph, and we see a 3 ft swell from the WNW with 9-second period. Energy hits 132 – still weak, but at least the conditions aren’t shredded. Still, it’s poor surf.
Wednesday the 5th back to cross-onshore from the NNW, swell drops to 2 ft, and the energy falls to 78. It’s small and messy.
Thursday the 6th has a bit more wind – 15 to 19 mph from the north and NNW, with a small 3 ft swell from the NNW but the period is a short 5 seconds. Energy at 115, but with that short period and strong cross-shore wind, it’s lumpy. Not for the longboard even.
From Friday the 7th through to the end of the first week and into the second, the swell barely registers. Most mornings have waves between 1 ft and 2 ft. Energy drops below 50 on many days, with the lowest being just 4 on Monday the 10th – that’s nothing. Winds are mostly moderate to fresh, cross or cross-onshore. You’d be better off doing something else.
Around Saturday the 15th, the afternoon shows a spike in swell height to 5 ft from the northwest, period only 6 seconds, energy at 207 – moderate energy – but wind is onshore from the west at 9 mph. That’s a short-period windswell, and it’s messy. The next day, Sunday the 16th, it’s back to 3 ft from the WNW with 7-second period and cross-shore winds.
The only glimmer in this whole forecast is Friday morning the 14th. There’s a 2 ft west swell, 8-second period, but the wind is a light cross-offshore from the NE at just 3 mph. Conditions would be clean. Combined energy is only 48 though, so it’s tiny. And early Saturday the 15th, the wind goes glassy – 2 ft from the WNW, 8 seconds, glassy conditions. That’s the closest we get to something clean, but it’s still tiny.
Water temp? I don’t have a specific figure, but the anomaly label is blank, which suggests it’s about average for this time of year – nothing wild.
To be honest, this is a blank run for the Reef (Reef). Nearly every day has poor surf conditions and scores of zero. For a reef break that’s exposed and fairly consistent usually, this length of quiet spell is a bit of a bummer. But forecasts change, and it won’t stay this flat forever.
Stay patient, my friend.

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.
