The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window, but I’ll be honest with you – it’s a tough stretch for Flynns Reef. This spot is a consistent, advanced-level reef break that’s fairly exposed to the SW, and the optimum swell direction is SW, so the swell direction is right. The problem is the wind. For the first several days, it’s all over the shop, mostly onshore or cross-onshore, and the wave comment is almost always "poor surf conditions." The water temp is sitting at 56°F with a 1°F anomaly, which is pretty much what you’d expect for this time of year, so no shocks there.
The first real chance of anything decent doesn’t pop up until Monday, August 31st, in the afternoon. We’ve got a 5ft SW swell with a 15-second period – that’s a groundswell, and it’s got some real push. The combined energy is 1261 (moderate wave energy), but the wind is a light cross-onshore, so it’s not going to be clean. The score is a 2 out of 10, and it’s called "marginal." It’s a maybe, but not a standout.
The next glimmer of hope is Wednesday, September 9th, in the afternoon. The swell is a solid 10ft from the SW with a 17-second period – that’s a very long period groundswell. The combined energy is a massive 7560 (strong to very strong). The wind is light and onshore (10 km/h), and the break is a reef, so that long period energy will shape up nicely. The score is a 4 out of 10, but it’s the best of the whole run. This is for experts only – 10ft is way too big for beginners. It’s a promising call, but it’s almost two weeks out, so keep an eye on it.
Thursday, September 10th, in the afternoon is another one to watch. The swell is 7ft from the SW with a 16-second period, energy at 2496 (strong). The wind is light and onshore again (10 km/h), making for clean conditions. It’s a 2 out of 10, but the conditions are right for a good session at a reef break.
The rest of the period is a write-off. There are huge gaps of nothing but poor surf and strong winds, especially from September 12th onwards, where it’s all cross-shore and messy. On Saturday, September 5th, the wind is a near gale at 34 mph, and the swell is 12ft – that’s blown out and dangerous. The setup looks more interesting for kite surfing than paddle surfing.
So, the standout is Wednesday, September 9th afternoon. It’s a long way off, but the combination of a big, long-period SW groundswell and light onshore wind on a reef break is the best we’ve got. If you’re an expert, mark it in your calendar. Otherwise, it’s a waiting game.
Rusty.

Information about the Flynns Reef Surf forecast
The above surf forecast table for Flynns Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Flynns Reef can be found by selecting the local surf guide option on the grey menu. Our Flynns 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 (Flynns 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 Flynns 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.
Flynns Reef is 32 km (20 miles) from Mornington. If you plan a holiday in Phillip Island, look for hotels and other accommodation in Mornington. Mornington has rooms for a wide range of budgets as well as car hire and transport links.
