The Lowdown
Alright, this is Rusty. Let’s get into it.
The next 16 days are a real mixed bag here at Roaches Reef. There’s a bit of a wait for anything decent, and even then, the standout moments are short-lived. The water is sitting at 68° – that’s 7° warmer than it should be for this time of year, which is very unusual. The early part of the week is a total write-off: Tuesday and Wednesday are plagued by choppy, cross-onshore winds and small, weak swell. The combined energy is barely a whisper (76, 56, 79), so don’t even bother paddling out.
Things start to look a little more interesting on Friday, September 4th. The morning brings a clean 6ft swell from the WSW, with a light cross-offshore breeze. The wave energy is moderate (357) and the period is a short 7 seconds, so it’ll be a bit walled up, but it’s the cleanest surf we’ve seen. That Friday morning session is the best on offer in the first week – it’s rideable and the wind is actually helping. The afternoon drops off.
Saturday the 5th is glassy in the morning with a tiny 2ft swell, but it’s almost flat. The energy is weak (90). It’s a dawn patrol for the longboard or nothing.
Then we hit a dry spell. From Sunday the 6th through to about Wednesday the 9th, the wind is a mess – strong cross-onshore and lumpy. The swell gets bigger, over 7ft, but with that wind it’s a complete write-off. The energy is strong (546, 826, 1001) but it’s just a churning mess. Not for paddling; that’s kite-surfing territory.
After a few more days of tiny, weak swell and poor conditions, there’s a very brief glimmer on Monday the 14th. The afternoon turns glassy, with a 5ft swell from the west. The energy is moderate (245) with a short period, but the glassy conditions will make it surfable. It’s a late-day session, and it’s the second standout of the outlook.
The last few days are small and inconsistent. The energy drops right off. Honestly, if you’re looking for a classic Roaches Reef session, focus on Friday morning the 4th and keep an eye on the Monday afternoon the 14th. The rest is a waiting game.
Rusty.

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.
