The Lowdown
Alright, let’s talk about Pitstops. This reef break is a consistent little beginner-friendly spot, but we’ve got a mixed bag coming over the next couple of weeks. Water temp is sitting at 86°, which is about average for this time of year – nothing wild. The optimum swell direction is southwest, and that’s exactly what we’re seeing for most of the good windows.
First up, Saturday the 18th afternoon – some clouds, glassy, and a small 2.6ft SSW swell with a 14-second period. Combined energy is 294, so it’s weak but clean. Not a standout, but okay for a beginner paddle.
Sunday the 19th is a write-off – risk of thunderstorms, onshore and cross winds, poor surf. Skip it.
Monday the 20th brings a solid pulse. Morning is marginal with a 4.6ft S swell at 17 seconds, but the wind is light cross. The afternoon though – glassy, 4.6ft S swell, 16-second period, and combined energy of 1062 – that’s moderate-to-strong energy. The waves will be clean and have some push. This is a good option, but the swell direction is south, not the optimum southwest, so it won’t be

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