The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming together for Long Reef over the next couple of weeks in the old units.
It’s going to be a slow start, no doubt about it. The first few days are a write-off, with barely a ripple on Tuesday the 14th – just 0.7 ft of weak south swell and no real energy to speak of. We’ve got a long gap of flat to poor conditions before anything worth paddling out for shows up.
The real action, and the standout for this forecast, is looking like Monday the 20th of July. The morning is still a bit questionable with rain showers and a cross-onshore breeze, but by Monday afternoon, things turn magic. The wind goes glassy, dead calm, and the reef will be clean as a whistle. Swell hits a clean 5 ft from the ENE with a solid 10-second period, and the combined energy is a solid 676 – that’s proper moderate wave energy. The water temp is sitting at 64°F, which is about average for this time of year, nothing weird there. This is the session to circle. Get on it.
Wednesday the 22nd also looks promising early. The morning is clear with a light cross-offshore breeze from the NW, and the swell holds at 5 ft from the ENE. It’s a touch smaller, but still clean and fun.
The next one to watch is Thursday the 23rd. The morning offers up 6 ft of east swell with a longer 11-second period, producing a combined energy of 810. Wind is light and cross-off from the WSW, so the reef should be looking nice and lined up. This is a solid, high-quality option.
After that, conditions get more mixed. There’s a window on Tuesday the 28th that deserves a mention. The afternoon looks very clean with a gentle cross-off breeze from the north, and a 4 ft east swell with a 13-second period. That long period means the waves will have some real push and shape, but at a beach break it might stand up a bit too straight. For a reef like Long Reef, that’s a good thing. The energy is still moderate at 579.
Around the 29th, the swell drops back to under 3 ft, and while the wind is offshore from the west, it’s not going to set the world on fire. The long-range window has some promise, but it’s a bit less certain.
So to wrap it up: the first week is mostly a bust. The standout is Monday arvo the 20th with glassy conditions and a decent 5 ft east swell. Thursday the 23rd morning is also a top pick. The rest is a mixed bag of wind, rain, and chop, with a few cleaner windows in the second week but nothing that screams epic.
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.
