The Lowdown
Alright folks, Rusty here. Let's have a look at what we've got coming up around Perelle Bay. It’s a reef setup that needs a specific key to turn on – a good blow from the WNW – but that’s been hard to come by lately.
Right now, we’re sat in a pretty flat spell with nothing to ride. The wind and sea state are a total mess for the whole of the coming weekend. We're talking lumpy cross-chop, fresh to strong cross-onshore winds, and poor surf conditions right through to Monday the 4th of September. It’s a real write-off for the next several days.
A change finally starts to creep in on Sunday the 6th of September. The swell drops right back to a tiny 3ft from the West, but the wind goes light, swinging to a clean cross-offshore from the south. The combined swell energy is weak (165), so these are tiny, clean, inside waves. Not worth paddling out for unless you’re just trying to wet the suit. Conditions improve a lot though. By Monday the 7th of September afternoon, it goes totally glassy with light winds from the SSE and a clean 4ft west swell (293 energy). That is a very brief window of actually decent, clean conditions for the spot, but the size is still on the small side for the advanced-level drop-ins here.
The actual standout for the whole outlook is on Tuesday the 8th of September morning. A real pulse of groundswell rolls in: 12ft from the West with a solid 11-second period. The combined energy is huge – 5104. That is a lot of juice for this reef. The wind holds clean and cross-offshore from the SSW. For advanced surfers only, this is the morning to circle on the calendar if you want size and shape in the water. The afternoon on that same day goes to crap with a cross-onshore wind, so be on it early.
After that, the forecast turns messy again with fresh to strong onshore winds through the rest of the second week. A bit of hope pops up on Saturday the 12th of September afternoon. The swell stays solid at 7ft from the west with a good 10-second period, and a very light ENE cross-offshore breeze cleans it right up (713 energy). That’s a very good chance for some strong, rideable waves if you are comfortable with that size on a reef. The Sunday after that looks too windy for clean surf for the most part.
So, if you are looking for the absolute best of a tricky forecast, pin your hopes on Tuesday the 8th of September morning for the biggest, most powerful session, or the Saturday the 12th of September afternoon for a cleaner, slightly smaller day.
Rusty.

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