The Lowdown
Alright, Rusty here. Let's break down what's brewing for Reef.
Honestly, mate, this forecast is a tough one to swallow. We're staring at a full 16-day stretch where there's just no surf worth paddling out for. Every entry is marked "poor surf conditions" with a score of zero.
From Thursday the 16th all the way through the rest of July, it’s a grind. Wave heights are tiny, mostly hanging between 0.7ft and 4ft, and the wind is almost always cross-onshore or onshore, chopping everything up. The swell period is short, mostly under 10 seconds, so there's no real push behind it.
Later in the run, around Thursday the 30th and Friday the 31st of July, the combined energy does pick up. Friday morning reaches 303 (moderate wave energy) and Friday afternoon pushes to 344 (moderate wave energy), with waves around 4ft from the NW. But the wind stays cross-shore from the north at 15 to 19 mph, and with a 9-second period, it's still messy and lumpy. Not clean.
This reef needs that clean, offshore wind to really work, especially with the optimum direction being from the SW. We're not seeing any of that the whole time. The water temp at the start on Thursday morning is about 66°, which is roughly 1° cooler than average, so nothing unusual—just standard for the season.
This is one of those stretches where you might as well get the wax off and wait. Conditions can flip, but in this window, there's nothing calling me down to the water.

Information about the Reef Surf forecast
The above surf forecast table for Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Reef can be found by selecting the local surf guide option on the grey menu. Our 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 (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 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.
