The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s coming down the line for Acid Drops. This is a reef setup, exposed to the south, so it needs the right direction to fire. For the most part, the next couple of weeks are a mixed bag of small, long-period groundswells and short-period windswell, with solid offshore winds being the main saving grace. It’s not going to be pumping every day, but there are a few sessions that’ll have you smiling.
The first real chance to get wet kicks off on Thursday the 27th of August. The morning starts off with a clean 3ft swell from the south, with a very long 17-second period. That’s proper groundswell energy, and with a moderate offshore breeze (ENE 20 km/h), it’ll be clean and lined up. The combined energy is moderate (633), still enough for a reef break like this to have some push. It’s an advanced wave, so you need your wits about you. The afternoon holds similar conditions, still with that south groundswell and offshore wind. This is the standout window of the first week.
Friday the 28th of August afternoon brings another highlight. You’ve got 3ft of S swell, 14-second period, and a solid offshore wind from the ENE at 25 km/h. The combined energy reads 567, slightly lower than the day before, but that offshore wind keeps it clean and well-shaped. This is another good session.
Moving into the second week, Tuesday the 1st of September afternoon looks promising. The swell is 3ft from the south, with a very long 19-second period. Offshore winds (NE 20 km/h) keep it clean. The combined energy hits 549. This is the pick of the second week.
Then, Wednesday the 2nd of September morning is a bit of a wildcard. The swell is 3ft from the SSW, 18-second period, with glassy conditions – the wind is virtually nothing (ENE 5 km/h). That’s as clean as it gets. The combined energy is 573. For a reef break, glassy and a long-period groundswell can make for some beautiful, though maybe a little fat, walls. It’s worth the paddle.
Toward the end of the run, Friday the 4th of September swings back to short-period, east windswell (7 seconds) at 5ft to 6ft. The wind is cross-offshore, so it won’t be as clean, and the energy is moderate. It’s surfable but not the quality of the earlier dates.
The real standout overall is Thursday the 27th of August (morning and afternoon) and Tuesday the 1st of September (afternoon) . The long-period south groundswell combines with reliable offshore winds, giving Acid Drops the clean, groomed lines it does best. You won’t want to miss those sessions.
Stay safe out there.

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