The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s on the menu for the next couple of weeks at Pitstops. This reef setup is a consistent little number, and it’s going to be serving up a steady diet of SSW-to-S groundswell for the foreseeable future. The water temp is sitting at a toasty 86°F which is a touch above the long-term average for this time of year, so you’ll be comfortable in boardies or a spring suit.
The first couple of days are a bit of a slow burn. Sunday the 30th is a write-off with onshore cross-chop and pretty weak energy (686), so don’t bother. Monday the 31st is where it starts to wake up. The morning session is the pick with a clean 4ft SSW swell and cross-off wind, giving you some decent energy (1217). That holds through Tuesday morning, too, with a similar 5ft swell and clean conditions. After that, the swell drops back a touch into Wednesday and Thursday, but the quality stays good for the morning sessions with light offshore winds and clean lines. The energy dips into the 300-400 range, so it’s small but fun.
Now, the real standout is the week ahead, especially the start of the second week. September 8th Tuesday morning is looking beautiful. A clean 4ft S swell, nearly glassy, and energy ramping up to 1197. Then Tuesday afternoon goes glassy with a 5ft S swell (1326 energy) – that’s worth a paddle. But the absolute gem is September 9th, Wednesday. Morning glass, 5ft S swell, energy hitting 2296, and the conditions are described as excellent for experienced surfers. That’s the one to circle. The afternoon stays glassy with a 4ft S swell that has a long 20-second period, so the waves will be lined up and powerful. This is groundswell gold for a reef, but the long period will mean long waits between sets.
The following week maintains a solid run of quality. September 10th and 11th keep the clean, cross-off windows with 5ft to 4ft S swell, though the 11th gets a bit of a breeze in the afternoon. September 13th Sunday afternoon is another big one: 6ft S swell, clean, energy at 1764, and excellent conditions for experienced surfers. That’s a big, powerful swell that’s going to be a handful for beginners. The run continues through September 14th with very good to excellent conditions.
Bottom line: the first week is about small, clean morning sessions, but the real heat comes from September 8th through the 10th, and then again on the 13th. If you’re an experienced surfer, the 9th is your day. Crowds are a possibility here, so get in early.
Rusty.

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.
