Table - best surf conditions forecast for Flatrock over the next 16 days.
The Lowdown
Alright, let's take a look at what's going on at Flatrock. Water's sitting right around 60°F, which is dead average for July, so no surprises there.
It kicks off on Tuesday, July 14th, but don't bother paddling out. You've got a solid 12ft SW swell with a ton of juice, but it's a messy cross-onshore wind, making it ugly.
The first real shot comes Wednesday morning, July 15th. Swell eases a bit to around 8ft from the SW, but the wind swings clean and cross-offshore from the NE. That's a proper groundswell with a 15-second period, offering plenty of power. At 8ft, this is advanced territory only – not for the faint of heart or the inexperienced.
After that, things get average for a few days. Mornings on the 16th, 17th, and 18th are clean enough, but the swell steadily drops and wind gets stronger. By Saturday the 18th, you're looking at only about 4ft of weak energy and the wind starts turning sour.
Then it's a dead zone. From Sunday the 19th right through Wednesday the 22nd, the wind is strong and the surf is a messy, lumpy write-off. Don't bother.
The Best of It
The real standout is Thursday morning, July 23rd, rolling into Friday, the 24th. On the 23rd, a new 10ft SW swell hits with insane energy. Wind is light and offshore from the SE. Clean, powerful, lined-up reef waves. Friday is just as good with 8ft SW swell and a light offshore from the East. This is the prime window for experienced surfers.
Saturday the 25th is also a gem. The swell holds at 8ft, and the afternoon goes glassy with zero wind. Flatrock under calm conditions is a beautiful thing. Just be aware that this spot can get busy sometimes, so you'll want to be early.
After that, things wind down. Sunday the 26th is still okay, but the energy drops and the wind gets cranky again towards the end of the month.
So, your best bet is to pencil in Thursday the 23rd through Saturday the 25th for the biggest, cleanest, and most powerful swell. It's a serious reef break, so leave the beginners at home.

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.
