Flatrock Surf Forecast and Surf Report

G’day, Rusty here, your local surf reporter. We’ve got a solid run of Southern Ocean groundswell lining up at Flatrock over the next fortnight, and it’s going to be a ripper for the experienced crew. The reef handles a serious amount of energy, and we’ve got a window of unreal conditions coming, with a standout day that’ll have the advanced boys frothing. Let’s crack into it.

The first session worth a paddle is Saturday morning, 4th July. There’s some clouds overhead with a light cross-off breeze from the SE at 6 mph, keeping things clean. Swell is a meaty 8.2 ft out of the SW, with a long 14-second period, so you’re getting proper groundswell energy. The combined energy is pumping at 2448 (moderate-strong). This is advanced territory—don’t even think about bringing a learner board. Conditions hold into the afternoon, with a 7.2 ft SSW swell and similar clean surfaces.

Sunday the 5th is the standout. Early morning, it’s crystal clear overhead, with a clean offshore wind from the E at 16 mph. This is premium—the reef will be groomed to perfection. Swell size jumps to 11.5 ft from the SSW, with a very long 17-second period. That’s a deep ocean groundswell delivering heaps of grunt. Combined energy is a massive 6602 (strong). This is only for experts—over 8.2 ft and punchy. The offshore breeze and long period mean the reef will have thick, lined-up walls, but it’ll break a bit straight in spots. By afternoon, it’s slightly smaller at 9.8 ft and 16 seconds, still with offshore flow, and still excellent.

Monday the 6th eases a bit. Morning shows clean 5.9 ft SW swell (14 seconds) with light cross-off wind. Combined energy is 1370 (moderate). Afternoon drops to 5.2 ft and 942 energy (weak-moderate). Still good, but a step down.

Tuesday the 7th morning has some cloud cover and a gentle cross-off, but the real treat is Tuesday afternoon—glassy, flat calm, with NE wind at just 3 mph. Swell is 6.6 ft from the SW, 16-second period, and combined energy of 2057 (moderate-strong). That glassy surface will have the reef looking like a mirror. Worth burning a work pass for.

Wednesday the 8th is another big day. Morning has 9.8 ft SW swell at 17 seconds, combined energy 5343 (strong), with clean conditions. Afternoon goes glassy again with a 8.2 ft SW swell (16 seconds) and 3808 energy (strong). For experts only.

Surf stays solid through Thursday the 9th and Friday the 10th, with 6.6 ft to 6.9 ft SW swells and offshore or light cross-off wind, energy in the 1200-1900 range. Clean but not as powerful.

Now for the grim stretch. From Saturday the 11th through to Monday the 13th, it’s dangerous. Saturday brings a near gale from the NW at 34 mph, cross-onshore, with 7.5 ft to 9.8 ft messy swell—blown out and ugly. Sunday is even worse: 14.8 ft to 13.1 ft SW swell but hammered by strong cross-onshore winds and lumpy conditions. Combined energy hits 11964 (very strong) but it’s a washing machine. Monday the 13th has a massive 19.7 ft SSW swell—combined energy 26728 (extreme)—but cross-onshore winds and choppy. This is kite-surf territory, not paddle. Avoid unless you want a beating.

Tuesday the 14th remains onshore and lumpy, with 11.5 ft to 13.1 ft swell and poor quality. The wind eases slightly, but it’s still onshore. Not recommended.

The light returns Wednesday the 15th morning. Glassy conditions again with a 7.5 ft SW swell, 15-second period, combined energy 2705 (moderate-strong). Clean surfaces, excellent for experienced surfers. Afternoon is similar with 7.9 ft and light cross-off.

Thursday the 16th is another cracker. Morning has 8.2 ft SW swell with a long 17-second period, light cross-off from the NE at 6 mph, combined energy 3657 (strong). Afternoon goes glassy with a 7.5 ft SW swell and 2642 energy (moderate-strong). The reef will be singing.

Friday the 17th drops down. Morning has 5.2 ft SW swell (13 seconds) and 959 energy (weak-moderate). Afternoon is 4.6 ft with 721 energy. Still clean, but nothing special.

Saturday the 18th shows 5.6 ft to 5.9 ft SW swells, but a moderate breeze from the NNE will add a bit of texture. A cross-shore chop by afternoon keeps it marginal.

Sunday the 19th closes the window with a 9.8 ft SW swell,
