The Lowdown
Alright, Rusty here, let's have a look at what's coming down the pipe for the next couple of weeks.
Right off the bat, we've got a bit of a slow start, but there's a solid window of clean waves coming up. The first real action is Wednesday afternoon, July 15th, at Trigg Beach. It's a beach and point setup, and we're looking at a 5ft swell from the WSW. The wind is a light NNE cross-off, so it's going to be clean. The water is a bit colder than normal at 64°, about 3° cooler than usual for this time of year, so you'll want a thicker wetsuit. The swell energy is strong (1552), and with a 17-second period, this is a proper groundswell – it's going to have some real push and shape, but at a beach break, it might wall up a bit. Still, it's the best on offer for the first few days.
Thursday the 16th gets messy. The wind swings to the NNW and picks up, and we get rain. The surf gets lumpy and chopped out. Friday the 17th starts okay with a clean morning, but the afternoon turns into a cross-onshore mess.
Then we get a big pulse. Saturday the 18th sees a massive 13ft WSW swell roll in, but the energy is insane (7081). The wind is a gentle cross-onshore, but that wave is just too big for Trigg – it's expert territory, and even then, it's going to be a washing machine. Not a day for a paddle; it's more of a kite-surfing show if you ask me. Sunday the 19th is still big, around 8ft, but the wind is light and the swell is dropping.
The real standout, the one to circle on your calendar, is the run from Monday the 20th through to Friday the 24th. The swell drops to a much more manageable 5ft to 6ft, and we get a string of clean, offshore or cross-off winds from the NE and ENE. The water might be a bit cold, but the waves will be clean with good shape. Thursday the 23rd and Friday the 24th are particularly good. Friday afternoon the 24th even goes glassy, with 4ft swell and zero wind – that's about as good as it gets for a session. The swell direction is mostly SW, which is a good fit for the break.
After that, the wave energy drops off significantly. By the 25th of July, we're down to tiny 3ft waves, and the week that follows is pretty gutless. The energy drops into the low hundreds, and the wind turns messy again. There's a little pulse of WSW swell on the 30th around 5ft, but it's a long 18-second period with a cross-on wind, which is a bit of a tease.
So, your best bet is the window from Wednesday the 22nd through Friday the 24th. That's where the quality and clean conditions line up. Get out there and enjoy it.

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.
