The Lowdown
Alright folks, Rusty here. Let’s get into the surf ahead for Flynns Reef. There’s a lot of water moving, but you gotta be smart about when you paddle out. The start looks mint before the wind turns it all to mush.
The first call is your standout. Sunday the 16th, early session at Flynns Reef (Big Island) is the pick. We’ve got a clean 4ft SW swell with a proper 14-second pulse. Energy is moderate at 726, and the water temp is 55°, right where it should be for this time of year. Light NE cross-offshore wind means it’s going to be glassy and perfect. That’s your session. The afternoon stays clean, just the wind shift a touch more south.
Monday the 17th keeps it going with a similar 4ft SW swell. The morning is clean with an offshore ENE breeze. The arvo picks up a 15 mph SE wind, but the swell period stretches out to 16 seconds, and the energy climbs to 931. Still a very good wave. Tuesday the 18th sees more of the same, with 3-4ft of SW swell and light winds keeping it tidy.
Now here’s where it turns. From Wednesday the 19th, the wind goes onshore and doesn’t let up. Wednesday and Thursday are poor, with bumpy, messy surf and the swell dropping off. Friday the 21st a new pulse of SW swell comes in at 4-5ft, energy jumps to 1670, but it’s buried under a strong north-west cross-onshore. Completely blown out.
The weekend is a full-on washout. Saturday the 22nd sees the swell jump to a solid 7-8ft with strong energy at 2567, but the onshore wind is relentless. This isn’t paddle surfing, it’s a full-on chaos zone, more for the kite crowd. Sunday the 23rd and Monday the 24th stay poor as the swell eases, but the wind stays messy and we even see some showers. It’s a grim stretch.
Tuesday the 25th is more of the same: fresh, messy winds and a churned-up ocean. Wednesday the 26th, the swell pulses again to a powerful 8ft, but the period is short at 10 seconds, and it’s crossed up by a strong south-southwest cross-onshore. That’s only for the brave, and even then, it’s hard to see much fun.
Finally, we get a reprieve. Thursday the 27th, the wind drops to a light south-southwest cross. The swell settles to 3-4ft with a gorgeous 17-second period. Energy is still moderate at 1158. The notes say “marginal,” so the tide might be a factor, but it’s a huge improvement. Friday the 28th stays similar, small 3ft swell and light winds. Saturday the 29th looks the same.
Then we get the second standout. Sunday the 30th, the afternoon goes dead glassy, zero wind. Swell holds at a clean 3-4ft, SW, with a 15-second period. Energy at 542. The comment says “good surf conditions.” That Sunday arvo is your golden window for the second week. A clean, gentle, long-period reef wave. Just remember, it’s further out, so treat it with a bit of caution. Monday the 31st looks like the cross-shore winds come back, so that Sunday window is the one.
So, to sum it up: two golden windows. Sunday morning the 16th and Monday the 17th, and then Sunday afternoon the 30th. The middle stretch is a mess. Stick to those windows.
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.
