The Lowdown
Alright, Rusty here again, let’s break down Trigg Beach. This spot is a beach and point, fairly consistent, so there's surf on the charts across the 16 days, but you gotta pick the right windows. Water temp is about 66°F, which is a little cooler than average for this time of year, but nothing crazy.
The first proper action kicks off Friday, August 29th. But the real standout is Saturday the 30th of August. The morning session is the one. We’ve got a clean 8ft swell from the WSW, with a period of 18 seconds – that's proper groundswell energy. The combined wave energy is 3237 (moderate to strong), and with an ENE breeze at just 3 mph, it’s almost glassy. This is for the experienced crew only though – over 8ft is expert territory. Get in early, because the afternoon breeze swings and messes it up.
Sunday the 31st still has size, around 8ft, but that wind goes onshore and it’ll get lumpy fast.
Through the start of September, it's mostly onshore junk. Thursday the 4th of September is a write-off with strong winds and rain. Friday the 5th is also a mess.
The next real gem is Thursday the 3rd of September morning. It's not massive at 7ft, but it’s a 14-second WSW swell and the wind goes dead glassy – a 3 mph northerly. That’s a rare treat – clean as a whistle and perfect for a longboard.
After that, there’s a window of cleaner, smaller surf around the 6th and 7th of September with 5ft to 4ft and offshore or cross-off winds – solid for a fun session. Tuesday the 8th of September afternoon has a nice 6ft WSW swell with a 15-second period and light cross-off breeze – clean and consistent.
A big pulse hits on the 10th of September. Swell jumps to 13ft from the WSW, 16-second period, with combined energy at 7434 (very strong). That’s way too big for Trigg – expert-only territory, and even then, it’s pushing the limits. The following days stay big at around 10ft, but with onshore wind, it'll be a messy closeout.
Bottom line: your two standouts are the morning of Saturday the 30th of August and the morning of Thursday the 3rd of September. Get out there while it’s clean.
Rusty.

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