The Lowdown

G'day, Rusty here with a look at what's coming up for Flatrock over the next couple of weeks. We've got a bit of a slow start, but the back half of the period is where the real action is, so don't write it off just yet.

The first solid session worth paddling out for is on Wednesday afternoon, the 15th of July. It's not going to be perfect, but there's a decent 8ft SW groundswell pushing in with a solid 14-second period, giving it some real grunt. The combined energy is strong at 2577, so you'll feel it. The water is sitting at 60°, which is pretty average for this time of year. The wind is a light cross-on from the NNW, so it'll be a bit bumpy, but it's manageable. The Thursday morning session on the 16th is actually cleaner with a cross-off breeze from the NNE, and the swell drops a touch to 7ft, still from the SW. That's a better window if you can get out early.

Friday morning the 17th also looks clean with a cross-off wind, but the swell is dropping to 7ft. The real standout, though, is the final weekend. Saturday the 25th of July has a massive 12ft SSW swell hitting the reef early in the morning, with a 17-second period and a combined energy reading of 6628. That's serious power. The wind is a slight cross-off from the SSE, making it glassy and clean. This is for experts only, no question. Then Monday the 27th of July is arguably the pick of the whole period. The morning shows a beastly 13ft SSW swell, but it's a bit lumpy with a cross breeze. The afternoon is where it's at: a solid 12ft SSW swell, 14-second period, combined energy of 10088, and the wind goes glassy cross-off from the SSE. That's exceptional surf, and it's all yours with clean conditions. The crowd factor at Flatrock is only "sometimes," so you might even have it to yourself.

The period in between is a mixed bag. The swell hangs around for a while, dropping to 4ft on the 22nd, but the wind turns onshore and messy. There's a big gap in good quality from the 19th of July through to the 24th, with choppy, cross-shore winds and onshore slop, so it's not worth getting too excited about. The end of the month on the 30th sees a huge 21-second period swell, but it's only 4ft and the wind is average, so it doesn't come together.

So, in short: the best of the best is that Monday afternoon, 27th of July, at Flatrock. The Saturday morning, 25th, is a close second for the big-wave crew. Keep an eye on the Thursday and Friday mornings for cleaner but smaller waves if you don't want the big stuff.

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.
