Alright, let’s talk Flatrock. First wave worth paddling out for is Tuesday morning, July 7th. This is a reef break, so it’s picky, and it’s for advanced surfers only.
Tuesday morning, July 7th, we’ve got a strong SW groundswell at 6ft, period a long 16 seconds, and combined energy at 1734. Wind is cross-off from the ENE at 12 mph, keeping it clean. Tides might be a factor, so you’ve got to time it. The afternoon cleans up more – offshore breeze from the east at 6 mph, swell at 6ft, energy at 1943. Excellent conditions for experienced surfers.
Wednesday, July 8th, is the highlight. Morning brings a big 10ft SW swell, 17-second period, energy at 4856. Wind is cross-off from the NE at 6 mph, and the surf is excellent for experts. Then the afternoon goes glassy with a slight air from the NNE at 3 mph, swell at 8ft, energy at 3587. This is as good as it gets.
Thursday, July 9th, stays solid. Morning has 6ft swell, 15-second period, energy at 1871, with a gentle cross-off from the NNE. Still clean. The afternoon hits 8ft but gets a little cross-shore chop.
From Friday, July 10th, it’s all downhill. Onshore winds kick in with rain. Swell stays big through the weekend, reaching 12ft by Sunday afternoon with energy at 4779, but the wind is screaming from the W and WSW at 22–25 mph. Flatrock becomes a kiteboarding zone, not a paddle spot.
Monday, July 13th, sees the biggest swell – 13ft from the SSW, 19-second period, energy at 10379. Cross-onshore and choppy, though. Afternoon may be marginal.
Next good window is Wednesday, July 15th. Morning has offshore wind from the ENE at 6 mph, 8ft SW swell, 15-second period, energy at 2215. Clean and excellent for experts. Thursday, July 16th, also offers a decent morning with 7ft SW swell and clean cross-off wind.
After that, strong winds and messy surf take over through the end of the outlook on July 22nd.
The best bet by far is Wednesday, July 8th, especially the glassy afternoon. Tuesday the 7th is a close second. Then you’re looking at a dry spell of almost a week until the 15th, which is normal for Flatrock when the wind turns ugly.

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.
