The Lowdown
Rusty here, checkin' in on Long Reef for the next two weeks.
First thing – the water temp is dead average for this time of year, no anomalies to report.
The surf kicks off Friday, July 31st. Early morning you’re lookin’ at chest-to-head high waves at 6ft, from the south. Period is short and a bit weak – 10 seconds – and the wind is a cross-off from the SSW at 12 mph. Keeps it clean, but the energy is only moderate. Afternoon goes cross-shore and choppy. It's rideable, but don't expect a classic.
Here’s your first real gem: Saturday, August 1st. Morning brings 5ft of SSE swell with a light offshore breeze from the WSW at 6 mph. Clean as a whistle. By afternoon, the wind drops to glassy – almost nothing from the NE. Same swell size, but the conditions are perfect. This is the session to chase.
Sunday the 2nd starts with 5ft swell and a long, juicy 13-second period from the SSE. That’s groundswell energy. Wind is a cross-shore from the north at 6 mph, so it’s not glass, but the wave shape could be really good. Energy is high, nearing 1000. The afternoon gets blown out by a moderate onshore, so go early.
Monday the 3rd drops to 3ft, clean but small. Tuesday the 4th is flat as a pancake – 0.7ft. Not worth wetting a wetsuit.
We get another pulse Wednesday the 5th and Thursday the 6th. Wednesday afternoon has 5ft from the south, clean with a gentle cross-off wind. Thursday morning is the pick: 6ft, light offshore breeze, moderate energy – a very good session.
From Friday the 7th through the weekend, it fades. Small, weak, and gets messy. The 8th, 9th, and 10th are mostly knee to waist-high slop with onshore or cross-shore winds – a real lull.
Then the big dog shows up. Tuesday, August 11th. Morning swell jumps to 7ft from the south with a fresh offshore wind from the WNW at 19 mph. Strong energy (1347). This is expert territory. The afternoon is the standout of the whole outlook: 7ft, 11-second period, clean offshore wind. The report says “excellent for experienced surfers.” If you’ve got the skills, this is your day.
Wednesday the 12th is a cleaner, smaller 4ft with offshore wind, but the wind is stiffer. Thursday the 13th remains clean and modest at 4ft.
The final stretch, August 14th and 15th, fades back to small, weak swell with some clean windows in the morning but no power. The 15th has a 3ft, 11-second easterly, but it’s crossed-up and messy.
Best sessions: Saturday, August 1st for a glassy, fun day, and Tuesday, August 11th for the real power – experts only. Everything else is catch-as-catch-can.
Catch ya in the water.

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.
