The Lowdown
Alright, Rusty here again. Let’s be straight about it—this is a rotten run for Roaches Reef. The next 16 days are mostly a flat, blown-out mess, and there's nothing to get your heart pumping.
For the first week, from Tuesday the 14th all the way through to Monday the 27th, we’re stuck in a flat spell. The swell barely moves above 0.6 ft for most of that, with combined wave energy struggling to get past 31—that’s just weak sauce. Water temp is a warm 69.1°, running about 9.5° warmer than normal for this time of year, so it’ll feel like a bath. There are a few glassy moments, like early on Saturday the 18th with 0.6 ft W swell, and again late on Saturday the 25th with a 2.2 ft WSW swell in glassy conditions, but the energy is so low it’s barely a ripple. Even a clean cross-off breeze on Thursday the 16th can’t dress up a 0.6 ft wave.
The swell does try to show up on Sunday the 26th with a 3.2 ft WSW swell and moderate energy (105), but it’s cross-on from the SSW and choppy. Not a good look. Then on Monday the 27th, we get a bigger bump to 5.2 ft from the WSW, and the energy jumps to a strong 438, but again it’s cross-on from the SE, turning a potentially fun reef into a rough, lumpy mess. The score is zero for a reason. Honestly, the kite surfers might find this more fun than we would.
The only flicker of possibility is Tuesday morning the 28th. The swell drops a bit to 4.6 ft from the WSW, but with a straight onshore wind from the S at 12 mph. There's energy there (245), but onshore wind kills quality. Hardcore experts only, and it would be a fight.
So, my honest call: save your energy. There are no standouts at all in this outlook. The reef is just not cooperating.

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