The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Long Reef.

We’re kicking off a bit slow, but the first real chance to get wet is on Wednesday the 22nd of July. It’s nothing huge, but it’s clean. We’ve got a 4ft swell from the ENE with a 10-second period, and the wind is a light cross-offshore from the WNW. The combined swell energy is moderate at 297. It’s not a world-beater, but for a midweek session, it’s a solid start. The water temp is about average for this time of year, so no surprises there.

Thursday morning the 23rd drops a little to 3ft from the ENE, but the wind swings to a clean offshore from the W at 9 mph. The energy drops to 130, but it’s a fun little wave if you’re not chasing size. Actually, the standout of the first week shapes up to be Saturday the 25th of July. The early session sees a 6ft swell from the S, with a period of 11 seconds, and that offshore W wind at 16 mph. The energy is up to 739 – that’s moderate to strong. This is a proper groundswell, and it’s going to have some punch. It’s a bit much for beginners, but for the experienced crowd, it’s going to be the pick of the week. The afternoon glass-off on Wednesday the 22nd is also a treat – 4ft, glassy, and 251 energy.

We hit a bit of a lull from Monday the 28th of July through to Tuesday the 29th of July, with tiny, poor waves. Then we get a bit of a kick later in the month. Wednesday the 30th of July gets a bit spicy, but it’s messy. The morning sees a 10ft S swell with a 12-second period, but the wind is cross-onshore, and the energy is a thumping 2502. This is big, powerful, and choppy. Only for experts, and even then, it’s not clean. The setup might be more interesting for kite surfers than paddle surfers.

The second week starts to look promising. Friday the 31st of July is a nice rebound with a 5ft S swell, clean cross-offshore wind, and 476 energy. Then look at Sunday the 3rd of August – a 7ft S swell, 8-second period, with a cross-offshore breeze. The energy is 568, so it’s solid. The wind is a bit stronger at 12 mph, but it’s clean. This is another one to mark on the calendar, but remember, it’s a week and a half out, so keep an eye on it.

The real standout for the whole outlook, though, is Saturday the 25th of July. That’s your best bet. Good size, clean wind, and a solid period. It’s a point break reef, so that long-period groundswell will wrap in nicely. Crowds are possible, but with that early morning offshore, you’ll want to be first out.

Stay frosty,
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.
