Thirroul Surf Forecast and Surf Report

Alright, Rusty here, let’s have a look at what’s on offer for Thirroul over the next couple of weeks.

Truth be told, the next few days are pretty average. We’ve got a bit of swell around, but the winds are messy and the quality is just not there. Thursday morning the 6th will see a small 3ft S swell with a short 8-second period and a light cross-offshore breeze, making for clean but very ordinary surf. The combined energy is weak at (114). Not worth getting excited about. Friday and Saturday are even smaller, with Saturday morning the 8th offering a glassy 1ft SSE swell, but it’s just too tiny to be any fun.

Sunday the 9th picks up a touch with a 3ft ENE swell, clean in the morning with a cross-off breeze, but the energy is still only moderate (120). Still not what you’d call a standout.

Now, Monday the 10th is where things get interesting. We’ve got a fresh offshore wind from the W at 30 mph and a 6ft ENE swell. The water temperature is about average for this time of year. The combined energy jumps to (472), which is moderate to strong. The morning session will be clean and offshore, but the swell period is a short 9 seconds, so it won’t have the same grunt as a longer period groundswell. Still, it’s the first real chance for a decent wave.

Tuesday the 11th is the real highlight. The afternoon is looking world-class for experienced surfers. A 7ft S swell with an 11-second period, light offshore wind from the W at 10 mph, and the combined energy is a strong (1036). That’s a powerful, clean groundswell. The direction is SE, which is right in the sweet spot for Thirroul’s exposed beach and reef setup. The conditions will be clean and glassy, but with that size and power, it’s strictly for the experienced crew. Beginners should sit this one out. Crowds are possible, as it’s a fairly consistent spot.

Wednesday the 12th still has a clean 4ft S swell in the morning with offshore winds, but the energy drops to (286). It’s a solid option, but not as good as Tuesday.

Things go quiet again from Thursday the 13th through to the 15th, with messy winds and drop in quality. Saturday the 15th has a decent 7ft S swell, but it’s short period and cross-onshore, so it’s a bit of a mess.

The next real standout is Sunday the 16th. The afternoon brings a 8ft E swell with a very long 11-second period, glassy conditions, and combined energy booming at (2002). That’s strong. It’s excellent for experienced surfers, but that size and power will be too much for beginners. The direction is E, which is good for the break, but a long period E swell can be a bit straight at beach breaks, so reefs and points handle it better. Thirroul’s reef section could be the pick.

Monday the 17th is huge. A 10ft ESE swell, also with an 11-second period, glassy in the morning. Combined energy is (1985). This is expert territory only. The wind is light and variable, making it clean, but the size is intimidating. Definitely not for the faint-hearted.

Tuesday the 18th still has a clean 6ft ESE swell in the morning with glassy conditions and moderate energy (779). A good option for those who are comfortable with solid waves.

Wednesday the 19th morning is another clean, 7ft ESE swell with light cross-offshore winds, energy (866). It’s a great option, but the afternoon gets chopped up by a strong NE breeze.

Thursday the 20th is consistent again, with a 5ft ESE swell in the morning, clean with light cross-offshore winds, energy (735). Still a very good session.

Friday the 21st winds down with a 4ft ESE swell, clean and light winds, energy (538). A nice, manageable end to the run.

Overall, the best on offer is hands down Tuesday the 11th afternoon and Sunday the 16th afternoon. Both are clean, powerful, and have excellent conditions for experienced surfers. The 16th has a slight edge on size and energy, but the 11th has the better wind and period. If you’re an expert, don’t miss these.

Rusty.
