The Lowdown

G’day, Rusty here. Look, it’s been a bit flat and ordinary around here for a while, but hang in there – we’ve got some decent windows opening up, especially for the more experienced crew.

The forecast starts quiet. Wednesday the 5th and Thursday the 6th are basically write-offs with tiny, weak swell, so don’t bother paddling out. We’ve got a dry spell of about four days with nothing worth mentioning. Friday the 7th morning sees a little pulse of 0.8m south swell, but it’s nothing to get excited about – just surfable, not special.

The first real flicker of something better comes Monday the 10th morning. Long Reef is showing a 1.8m easterly swell with a period of 9 seconds, and a solid 30 km/h westerly offshore wind. That’s clean, but the swell’s pushing into that 1.5m mark, so it’s getting a bit stout for beginners. The combined energy’s moderate-to-strong (538). Still, with that fresh offshore, it’s a good choice for advanced surfers looking for a proper session.

Tuesday the 11th is the standout in the first week. The morning sees a clean 1.6m south swell under a light cross-offshore breeze, and the afternoon cleans up further with a 1.5m south swell and 15 km/h offshore wind. The period bumps to 10 seconds, which gives the waves a bit more shape and punch. This is easily the best on offer in the early run – just a solid, fun day at Long Reef.

We get a bit of a lull again mid-week, but then Thursday the 13th morning is a big one. A 2.1m south swell, 8-second period, and a light cross-offshore wind. The combined energy is massive (1206), which is strong to very strong. This is expert territory – too big for beginners, and the short period means it’ll be a bit punchy and maybe a bit close together at the beach. For the experienced crew, it’s excellent. The water temp is about 18°, which is pretty normal for this time of year.

The next real highlight is much further out. On Tuesday the 18th, Long Reef (Big Island) is looking promising again. Morning session has a 1.6m south-southeast swell, 10-second period, and light cross-offshore wind. The combined energy is 571 – solid moderate energy. The water’s clean, the swell’s a good size, and it’s long period enough to have some proper push. This is a long-range call, so it’s promising but not set in stone.

There’s a little more action on the 20th Thursday morning, with a 1.0m southeast swell, 10-second period, and a glassy offshore wind. Small but clean – a nice little session for a grovel board.

So, to wrap it up: the best bets are Tuesday the 11th, and if you’re patient, the long-range promise of Tuesday the 18th. For the big-wave hunters, Thursday the 13th morning is your day. The rest is a mix of small, choppy, or just plain ordinary. Stay tuned.

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.
