The Lowdown
Alright, Rusty here, looking at the long-range for Pinetrees. It’s a slow start, but there’s a real good window of surf coming, and one day that’s got me fired up.
Water temp is about normal for this time of year, nothing crazy.
The week kicks off on Monday, August 31st with some energy in the water, but it’s not much. We’ve got a 6ft to 6ft ENE swell, short period at 8 seconds, and a moderate cross-off breeze from the east at 12 mph. The combined energy is moderate (437), but it's a marginal call. This same pattern of small, short-period swell and cross-off wind holds through Tuesday and Wednesday. It’s surfable, but nothing special.
Thursday, September 3rd, the energy nudges up a bit with a 6ft swell (488), but the afternoon goes cross-shore and messy. Friday the 4th, the swell builds to 7ft to 7ft from the ENE, still short period, but the energy is climbing into the moderate range (622 to 732). The wind stays cross-off, keeping it clean. It’s not a standout yet, but the ocean is waking up.
Saturday the 5th, the swell hits 7ft to 8ft, and the combined energy is strong (1010) in the morning. There’s a risk of storms, but the wind is cross-off, so it’s clean. This is where the bigger-wave crew should start paying attention.
Now, here’s the real standout. Sunday, September 6th. That morning, we’ve got a 8ft swell from the east, but the period jumps to 13 seconds – that’s genuine groundswell. The combined energy is very strong at 1913. The wind is offshore from the ESE at 12 mph, glassy clean. This long-period swell is perfect for a point break like Pinetrees – the waves will have real shape, power, and longer lulls between sets. This is the session to aim for. The afternoon stays similar, with a 7ft swell and 1667 energy.
Monday the 7th holds similar strength with a 7ft east swell at 12 seconds (1520), but the wind goes cross-shore in the afternoon, so get out early.
Tuesday, September 8th – the swell is too big. We’re talking 10ft to 13ft with energy over 3000. The wind is cross-shore and cross-on. This is a kite-surfing day, not a paddling day. Leave it for the experts.
Wednesday the 9th is a beautiful reset. The wind swings offshore from the SSE, light at 9 mph, with a 6ft ENE swell at 9 seconds. The energy is moderate (723), but the conditions are clean, and the forecast says “very good surf conditions.” This is a fun, clean session for intermediates.
After that, the swell fades. From Thursday the 10th through to the end of the forecast, we’re looking at smaller swells, 3ft to 5ft, mostly short period, with cross-off winds. The energy drops back into the 200s to 300s. There’s a small bump on the 13th with a 4ft, 10-second swell, but it’s nothing to get excited about.
So, bottom line: the first week is a grind, but Sunday, September 6th is the absolute standout – big, powerful groundswell with clean offshore wind. That’s your day. The 9th is also a nice, clean option for a more relaxed paddle. The rest is just background.
Rusty.

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