The Lowdown
Grab your board, but maybe leave it in the car for a bit. This 16-day stretch for Triggs Beach is looking pretty grim, to be honest. We're talking a whole lot of flatness and onshore slop, with only a couple of tiny windows that might get your hopes up before dashing them. The water temp is sitting at 57°, which is about average for this time of year, so that’s not the problem – it’s everything else.
Right from the get-go, Sunday the 9th is a no-go. The swell is a weak 4ft from the north with a short, crumbly 5-second period, and the energy reading is a paltry 59. A moderate cross-shore breeze is going to chop it right up. Monday the 10th offers up a similarly small 4ft WSW swell, but the wind is on it and the period is a gutless 6 seconds. We're looking at weak energy (69) and poor conditions.
The middle of the week doesn't get any better. Tuesday the 11th and Wednesday the 12th see a bit more size, up to 5ft and 5ft, but it's still that short-period, wind-blown stuff. The energy picks up to a moderate 147 and 136, but the wind is onshore or cross-onshore, creating a lumpy, choppy mess. Not worth the paddle.
Then, from Thursday the 13th through to Monday the 18th, it just goes flat. We're talking 0.3ft of swell from the south with wicked long periods of 14 to 16 seconds, but there's just no energy behind it at all – those energy readings are all below 10. It's a lake out there. So that's a solid six-day gap with nothing on offer, which is just a kick in the teeth.
Things try to stir again on Tuesday the 19th. The morning is still flat, but by the afternoon we get a tiny 2ft north swell creeping in. The energy is still weak (18), and it's from the wrong direction for this break. It's just not enough to do anything with.
The final week brings a couple of pulses, but they're junk. Wednesday the 20th sees a bigger 5ft WSW swell, but it's cross-onshore and choppy with a 6-second period, so it'll be a washout. The energy is moderate at 183, but the quality will be terrible. Then the 21st gets hammered with 25 mph winds and barely any swell – that's more of a kite-surfing day than a surfing day. The rest of the period into Sunday the 24th fades back into tiny, weak, and mostly messy surf or flatness.
Honestly, there's nothing here that gets me excited. There are no standouts. The reef at Triggs is sheltered and needs a solid WSW groundswell to work, and we just don't get one of those with clean winds in this entire window. It's a long, bleak outlook. Keep the board in the bag and maybe go for a run instead.
