The Lowdown
Alright folks, Rusty here again. Let’s break it down.
The next couple of weeks at Long Reef start off slow but get real good later. This is a reef break for the advanced crew, exposed to the south-east, and fairly consistent.
Kicking off on Thursday the 30th of July morning. Solid 8ft swell from the south, 10-second period. Combined energy is pumping at 1757 (moderate-to-strong wave energy). Water temp is 65°, right about normal for this time of year. Winds are light cross-offshore from the southwest, giving you clean conditions. This one is for experienced surfers only, as it’s over 5ft. First standout. Loads of power.
Thursday afternoon goes downhill fast – wind swings cross-on from the SSE, swell drops to 5ft, energy down to 411. Choppy. Forget it. Friday morning the 31st is clean again, 7ft south swell, 10-second period, but the quality isn’t holding. Afternoon is messy.
Saturday the 1st of August has a cleaner morning. 5ft from the SSE, offshore from the WSW, clean. Combined energy moderate at 493. Rideable but not a ripper. Sunday the 2nd gets some long-period 12-second swell at 6ft, energy moderate at 993, but the wind is average. The long period means better shape on the reef.
Monday the 3rd is flat and weak. Tuesday the 4th is tiny – 1ft, 46 energy. Don’t bother.
Wednesday the 5th picks up. Morning has 5ft south swell with clean offshore winds. Moderate energy at 425. Good for a paddle. Thursday the 6th is small but clean.
Then a lull: Friday the 7th through Saturday the 8th are poor. Sunday the 9th of August turns the corner. Morning brings 5ft south-southeast swell, 10-second period, light offshore wind. Combined energy 555. Very good conditions. Second standout.
Monday the 10th morning is a beauty: 6ft from the SE, 11-second period – proper groundswell. Energy 758. Light cross-off wind, clean. Tuesday the 11th morning: 7ft from the SE, short 7-second period, gentle offshore. Energy 707. Very good. Wednesday the 12th is even bigger: 8ft from the SSE, 8-second period, offshore all day. Energy strong at 797. Only for the experienced. Friday the 14th of August morning – headline: 7ft from the south, offshore wind, energy strong at 1097. Excellent for experts. Clean and powerful.
Crowds can be a problem when it’s this good. Get out early.
First standouts: Thursday 30th July morning. Second: Sunday 9th August morning. The run from Monday the 10th to the 12th is excellent, with Friday the 14th the big finish.

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.
