The Lowdown
Alright, Rusty here. Let’s have a good look at what’s on the table for Long Reef over the next couple of weeks. It’s a mixed bag, but there are a couple of moments that’ll get the blood pumping.
The week kicks off somewhat quiet. Monday morning the 7th sees a small, clean 5ft swell from the South with a short 8-second period, and a light cross-offshore breeze from the Northwest. The water temp is sitting at 65°, which is spot on for this time of year. You’ll get a few fun ones, but it’s nothing to write home about. By the afternoon, the wind swings onshore and the quality drops.
Tuesday the 8th is a washout. The swell bumps up to 8ft from the South, but a strong cross-shore wind from the SSE makes a mess of it. That combined wave energy is pumping at 1005 (moderate to strong), but the conditions are just too lumpy for a good paddle. Wednesday the 9th gets even uglier with heavy winds, so don’t bother.
Thursday the 10th through to Saturday the 12th morning shows some real potential. The standout in this entire run is Saturday morning the 12th. The swell drops to a clean 5ft from the SSE, but the period stretches out to 11 seconds – that’s proper groundswell energy. The wind is glassy, light offshore from the West. The combined energy sits at 724 (moderate). I’m talking clean, lined-up waves with that longer period giving you some power. This will be a beauty for any surfer in the water.
Right after that, the surf fades. From Sunday the 13th all the way through to Monday the 21st, it’s mostly small, windy, choppy, or just plain poor. There’s a long, frustrating gap of about nine days where the recommendations are slim. A few mornings might have a clean face, like Thursday the 17th morning with a solid 8ft from the SSE, but it’s onshore wind. That one’s more of a messy grind for experienced surfers only.
Then, the real hidden gem appears. Tuesday morning the 22nd is the true standout of the entire 16-day forecast. We’re looking at a 8ft groundswell from the South with an 8-second period – but the key here is the wind. It’s glassy, flat calm from the East. The combined swell energy is 1072 (moderate to strong). This is a window of pure, glassy perfection for experienced surfers. The waves will be clean, walled, and without a breath of wind. Keep an eye on this date.
So, to sum it up: the two big sessions to aim for are Saturday morning the 12th and Tuesday morning the 22nd. The rest of the period is mostly a wait-and-see.
Stay wet.

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.
