The Lowdown
Alright folks, Rusty here, looking at the next 16 days for our local stretch. I gotta be straight with you—this one’s a tough read. The forecast is a flat spell with no real surf to speak of. We’re looking at a long stretch of nothing, with no real standouts on the horizon.
Let’s start with the first bit of action, or lack of it. From Friday 14th August right through to Saturday 29th August, the story is the same: tiny, weak waves. The only break on the radar is Walton Rocks (Power Plant), a beach and reef setup that’s very consistent but needs a decent swell to work. For the first week, we’re seeing nothing but 0.3ft to 1ft of swell, mostly from the east with a period of 5 to 13 seconds. The combined energy is pitiful—just 8 (on the 14th) to 29 (on the 16th) in the weak range. The wind is a mixed bag, but even when it turns glassy or offshore, like on Sunday morning 16th August with a light 3 mph SW breeze, there’s just no swell to push.
The water temp is sitting at 85°F with a 0.5°F anomaly—pretty much normal for this time of year, so that’s not the issue. The problem is a total lack of energy. The best we see is Sunday afternoon 16th August, with a 1ft ESE swell and a 5-second period, but it’s cross-shore and choppy. Not worth paddling out.
Moving into the second week, from 22nd August onwards, we get a slight uptick in swell height, but it’s a disaster for quality. By Monday 24th August, we’ve got 2ft to 3ft of swell, but the period drops to 4-5 seconds—short and weak. The combined energy climbs to 39-54 (still weak), but the wind is cross-onshore or onshore from the east and northeast, blowing 12-16 mph, making it choppy and messy. By 26th and 27th August, we’re looking at 3ft swell with an onshore NE wind at 16 mph—that’s about as bad as it gets. The setup is more interesting for kite surfing than paddle surfing, honestly.
Through the 28th and 29th, it fades back to 0.7ft to 1ft with onshore winds. No standouts, no good windows. The forecast confidence is pretty high on this being a washout—there’s just nothing to grab onto.
Bottom line: if you’ve got a board, save the wax. The 16-day window is a blank run. I’d say it’s a normal quiet spell for this area, but it’s a bummer. Don’t hold your breath—forecasts can change, but right now, there’s not a single surfable day in sight.
Rusty.
