The Lowdown
G'day, Rusty here, and I've been staring at the charts for your local zone. It's a bit of a rough start, but we've got a couple of absolute gems hidden in the second week if you're willing to be patient.
Alright, for the first few days, it's proper grim. Monday the 7th is a write-off with a strong cross-breeze making a mess of things. The swell is 4 ft from the WSW, but the wind is howling 25 mph from the SSW, so it's just a chop-fest. Tuesday the 8th isn't much better, with a strong 5 ft SW swell (17-second period) but the wind is still on it, making it marginal at best. Wednesday the 9th and Thursday the 10th see a big jump in size – we're talking 10 ft to 12 ft from the SW – but with strong cross-onshore winds and a combined energy of 5690 and 9388, it's powerful but a total mess. That's a big, choppy, ugly ocean, only for the absolute hardcore. Friday the 11th is still a bit rough and marginal.
Now, here's where it gets interesting. Saturday the 12th is your first real standout. The morning brings a clean 6 ft SW groundswell (16-second period) with a light N wind creating a cross-off breeze. The combined energy is 1384, so there's some proper push. Flynns Reef is a consistent, advanced reef break, so it's for the experienced crew. The crowd factor is "often", so you'll have company, but the conditions are "excellent" for the skill level. The afternoon glass off with a 5 ft SW swell and light SE wind is a beautiful thing, making it clean and glassy. That's your Saturday session sorted.
Sunday the 13th and Monday the 14th get blown out again by a fresh breeze, so we're back to poor conditions. Tuesday the 15th is a bit of a mixed bag with a 8 ft SW swell coming in, but it's only 11-second period and the wind is light, so it's still a bit lumpy. Wednesday the 16th is a bit better with a 7 ft SW swell (16-second period) and a light cross-breeze, but still only marginal.
Alright, hold on for the real payoff. The following week is promising. Saturday the 19th afternoon sees a 7 ft SW swell with a 19-second period – that's very long-period groundswell, perfect for a reef like Flynns. The wind is a light SW cross-onshore, so it's a bit rippled, but the energy is strong (3166). Then, Sunday the 20th morning is a standout. We get a 5 ft SW swell with a light offshore ESE breeze at 6 mph. The conditions are "clean" and the combined energy is 1297. It's a very good session.
But the absolute best of the whole forecast, the one you circle on the calendar, is Monday the 21st. The morning is good with a 4 ft SW swell and offshore E wind, but the afternoon is the killer. We get a 8 ft SW swell (14-second period) with a gentle offshore E breeze at 9 mph. The combined energy jumps to 2764, the conditions are "excellent" for experienced surfers, and it's clean. That's a big, powerful, clean swell hitting a consistent reef. That's your day. The water temp is about 57°F, which is pretty normal for this time of year.
So, the long-range standouts are the 21st and 22nd of September. The 22nd has a solid 7 ft SW swell (19-second period) with a clean cross-off breeze, but the 21st afternoon is the clear winner. The rest of the window is mostly blown out or marginal. Don't expect much until the weekend of the 19th, but when it fires, it fires.
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.
