The Lowdown
Alright, Rusty here. Let’s break down what’s on offer at Roaches Reef.
Honestly, this 16-day window is a tough one. There’s a long stretch of flat, weak conditions right from the start, and it takes over a week before we see any real size. Patience is the name of the game.
From Monday July 27th through to the end of the month, it’s a washout. Swell is tiny – 1ft to 3ft – mostly from the west or west-southwest, with a short, weak period of 5-6 seconds. The combined energy barely hits triple digits, often sitting below 100. Winds are cross or cross-off but still strong enough to keep things messy. The best we get is Friday July 31st morning: a 4ft west swell with a cross-off north-northwest breeze (12 mph) giving a clean surface, and energy hits 120. Still, it’s poor surf – too short-period and weak to get excited over.
Then we hit another dry spell. Saturday August 1st through Wednesday August 5th is the same story: 1ft to 2ft swell, weak energy, and winds mostly onshore or cross-onshore. Water temp is about average for this time of year.
The first real pulse arrives late in the second week. Friday August 7th morning shows a 5ft west-southwest swell with a 7-second period, and the combined energy jumps to 308 – finally some moderate power to work with. The wind is light onshore from the south at 6 mph, but it’s flagged as marginal with questionable tide conditions. Not a clean session, but it’s the biggest swell of the run. Saturday August 8th morning holds a 5ft west-southwest swell with a light west breeze at 6 mph, energy at 228, and a cleaner look with just small wind ripples. Still, that 7-second period means short, dumpy waves – better for a bigger board and a lot of paddling.
For experts, that Friday and Saturday of the second weekend are the only real options. For everyone else, it’s a long, flat stretch. Roaches Reef is usually consistent, so this kind of blank run is a bit unusual – forecasts can shift. But right now, the kite surfers might be having more fun in those afternoon cross-shore breezes than we are.

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.
