The Lowdown
Hey folks, Rusty here with a look at what’s cooking at Courtown for the next couple weeks. I’ll be honest – it’s a lean patch, but there’s a blip or two worth paddling out for.
The first week is pretty much a dud. Wave heights are stuck at around 0.3ft to 0.7ft, with the odd offshore breeze keeping it clean but totally flat. Combined swell energy is down in the single digits to the 20s (weak energy). Even with a long period of 15-17 seconds, there’s nothing to push you down the line. You’d be floating.
Tuesday the 25th brings some light rain and a cross-onshore wind with a 4ft swell from the SSE, but it’s only a 5-second period. Energy hits 67-82 (still moderate), but it’s lumpy and messy – not point break waves, more like wind-chop play.
Your best shot comes on Monday the 31st of August. The afternoon delivers a 5ft swell from the SSE, period 8 seconds, and a combined energy of 238 (moderate energy). The wind is cross-onshore, so it won’t be perfect, but that’s the most juice we get all outlook. For a point break, that’s your highlight.
The mornings around Tuesday the 1st of September also have clean offshore wind from the W with a 2ft S swell (energy 78), but it’s small. Water temp is about normal for the season.
Bottom line: there are big gaps of flatness between any real hope. That’s normal for this area right now. Keep your eyes peeled, but don’t expect much.

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