The Lowdown

Alright folks, Rusty here with the imperial version. Let’s have a look at what’s shaping up at Flynns Reef. We’ve got an 16-day window, and the first bit of proper surf isn’t really on the cards until Sunday afternoon. The week ahead is a bit of a mixed bag, but there are a couple of moments that’ll have you pulling on the wetsuit.

The overall pattern is a solid SW swell train, but the wind is the real story here. It’s going to be a battle between those clean conditions and the cross-onshore stuff that’ll make it messy. The combined swell energy is moderate to strong, with values ranging from 395 to 6736.

Sunday morning the 23rd is a write-off. That 6ft SW swell (14 seconds) is there, but a 9 mph cross-on from the NNW is making it choppy and marginal. Not worth the paddle.

But then, Sunday afternoon the 23rd... that’s where it’s at. The wind drops to a glassy 3 mph from the west. The swell is a solid 6ft from the SW with a 15-second period, and the energy is pumping at 1509. It’s clean, it’s glassy, and this is the standout session for the week. For experienced surfers, this is as good as it gets. The reef will be handling that long-period groundswell beautifully.

Monday the 24th is a write-off again. Tuesday morning the 25th is a tease – a clean 4ft SW swell (13 seconds) with a light cross-off from the ENE, but it’s small. The afternoon goes straight onshore and ugly.

The next real window of opportunity is Friday the 28th. The morning is choppy with a 5ft, 18-second swell, but the afternoon is promising. That 6ft SW swell (17 seconds) with a light cross-shore from the south at 6 mph and energy at 2093 will be offering some solid, long-period waves. It’s a marginal call due to tide, but it’s the best of the second half of the week.

Saturday the 29th is messy with onshore winds. Sunday the 30th afternoon has a bigger 7ft SW swell (17 seconds) with a 2644 energy reading, but that cross-on wind from the WSW will be making it bumpy. A step down from Friday.

Looking further out, Monday the 31st has a similar story – decent swell but cross-on wind. Tuesday the 1st of September is a total write-off with strong, messy winds. Wednesday the 2nd morning has a clean 5ft SW swell (13 seconds) with a light cross-off from the NE, but it’s only a brief window before the wind picks up again.

After that, it gets rough. Thursday the 3rd sees a big, messy 13ft SW swell (12 seconds) with a brutal onshore wind. That’s a kite-surfing day, not a paddle day. The energy is off the charts at 6736, but it’s a washing machine. Friday the 4th is also huge – 10ft, 17-second SW groundswell – but again, the wind is trash. The rest of the window into the second week is just a repeat of lumpy, cross-onshore conditions.

The best on offer:
The standout is Sunday afternoon the 23rd. That glassy, 6ft SW swell at Flynns Reef is the pick of the whole 16 days. The water temperature is about average for this time of year, so no surprises there.

The second best is Friday afternoon the 28th. That 6ft, 17-second SW groundswell with a light cross-shore wind will be a good session, but not as clean as the Sunday.

Remember, Flynns Reef is a consistent reef break that’s fairly exposed to the SW, so it needs the right direction. It’s an advanced spot, and crowds are often a factor. For a long-period swell like this, the reef is where you want to be.

Rusty out.

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.
