Thirroul Surf Forecast and Surf Report

Alright, let's talk about what’s on the cards for the next couple of weeks.

Honestly, the first week is a bit of a mixed bag. We’ve got some good clean windows, but nothing to get properly excited about until the end of the month. The real story is a big pulse of energy that’s forecast to roll in late next week, around the 30th of July. That’s the one to mark on your calendar.

For the immediate future, Thirroul is your spot. Monday morning the 20th of July is the pick of the early days. We’re looking at a clean 5ft swell from the ENE, with a nice 11-second period pushing in. There’s a light offshore breeze from the NNW, so the face will be clean. The combined wave energy is sitting at 723, which is a solid, workable amount of power. It’s a decent start to the week.

The swell drops off a bit through Tuesday and Wednesday, but the mornings remain clean with light offshores. The wave energy drops into the low hundreds, so it’s smaller and more relaxed. The wind holds for the morning sessions, making it worthwhile for a longboard or a funboard.

Now, Thursday the 23rd of July, the swell drops right out. The energy is down in the 70s and 80s. It’s pretty flat, so give it a miss.

Friday the 24th of July sees a new S swell showing up. The morning brings a clean 5ft from the south, with a 9-second period. The wind is a light cross-off from the WSW, so it’s clean. The energy is back up to 413. This is a good little window.

The weekend of the 25th and 26th of July is interesting. Saturday afternoon has a bump in energy to 496 with a 4ft S swell and a 12-second period, but the wind is a bit of a cross-off. But Sunday morning the 26th of July is a standout. The wind drops to absolutely glassy, zero knots from the S. The swell is 5ft from the south, with a 10-second period and energy of 444. That glassy morning is going to be beautiful. The afternoon gets a bit onshore, so get it early.

The early part of the following week, Monday the 27th and Tuesday the 28th, is small and ordinary. The energy is low, and the swell is only around 2ft to 3ft. It’s not really worth paddling out for.

Then we hit the big event. Thursday the 30th of July is the one. The forecast shows a massive S swell arriving. The morning is a powerful 12ft from the south, with an 11-second period, and the wave energy is a huge 5097. That’s proper, heavy energy. The wind is a cross-off from the W at 15 mph, so it’s going to be raw and powerful. This is for experienced surfers only. The afternoon gets even bigger, with a 13ft S swell, a 13-second period, and a massive 8046 energy reading. The wind stays cross-off. This is a solid, solid groundswell.

Friday the 31st of July keeps the size at 10ft from the SSE, but the wind turns onshore and choppy in the afternoon. Morning is still workable with a light cross-shore, but the size is still big. Saturday the 1st of August is similar, with 8ft to 10ft, but the wind is onshore again. It’s big, but messy.

The pick of the second week might actually be Sunday the 2nd of August. The swell is still 7ft from the SSE, but the wind is glassy in the morning. The energy is 868. That’s a clean, big morning that’s worth a look.

The water temperature is about average for this time of year at Thirroul, so nothing unusual to report on that front.

The 30th of July is the big one. It’s a long-range call, so keep an eye on it, but if it holds, that’s the swell of the month. It’s an exposed beach and reef setup, so it’ll handle the size, but the period is long, so it might be a bit straight at the beach. The reef should be the go.
