The Lowdown
Alright, Rusty here. Let's break down what Flatrock's got cooking for us.
We've got a bit of a wild ride ahead. The water's about average temp for the season, nothing unusual there.
The first few days are pretty much a washout. Friday the 24th and Saturday the 25th have solid swell but the wind is cross-onshore, making it choppy and ugly. Not worth your time. Sunday the 26th and Monday the 27th are even worse with strong winds. So, a rough start for sure.
Things start to look a little more interesting towards the end of next week. Wednesday the 29th has a big 12ft SSW swell with a very long 15-second period. The energy is massive (5088). The wind is still cross-onshore, but light, so it's not a total loss. Thursday morning the 30th is the real standout early on. That's when we get glassy conditions, a clean 7ft SW swell, and a 13-second period. The energy is moderate (1566). For an advanced spot like Flatrock, that’s a proper window. It’s not huge, but it’s clean, and the lack of wind makes all the difference. Expect a crowd – it’s a known spot and when it’s good, people know.
Now, if you’ve got patience, Sunday August 2nd is the big one. We’ve got a 10ft SW groundswell with a 17-second period, and the wind is a light offshore cross-off. The energy is high (5967), and the conditions are described as exceptional for experts. This is the pick of the entire two weeks. It's a point break setup here, and that long period is going to make for some proper, lined-up waves. Just be aware, this size (over 8ft) and long period is only for experienced surfers. It'll be a bit too much for beginners. The offshore wind will keep it clean, and that’s a major positive. There’s also a good chance of crowds, as is typical for such a good-looking day.
Monday August 3rd is a solid follow-up, with a 10ft SSW swell and a 16-second period, with clean offshore winds in the afternoon. Another great day for the advanced crew.
The second week overall looks more promising for clean conditions, but the swell drops off. The standout remains Sunday the 2nd. After that, we see smaller, cleaner waves into Tuesday and Wednesday, but nothing compared to that early August swell. The very end of the forecast period, around Friday and Saturday August 7th and 8th, looks like it gets messy again with strong winds.
So, to sum it up: the start is rough, but Thursday July 30th morning is a solid, clean option, and Sunday August 2nd is the absolute standout – a classic Flatrock day for experts. The gaps in good surf are only a few days at a time, so don't lose hope.
Rusty.

Information about the Flatrock Surf forecast
The above surf forecast table for Flatrock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Flatrock can be found by selecting the local surf guide option on the grey menu. Our Flatrock 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 (Flatrock) 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 Flatrock 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.
