The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cookin’ at Dumps.
Right off the bat, we’ve got a bit of a rough patch. The first few days are a write-off for any decent paddle. Wednesday the 2nd and Thursday the 3rd are serving up onshore chop and weak, messy swell. You’re looking at a cross-on wind mess with waves around 3ft to 6ft and a short period. The combined energy is moderate (242 to 481), but it’s all just blown-out junk. Not worth wetting a wetsuit.
Friday the 4th is a real tease. A big WNW groundswell rolls in, pushing 12ft to 13ft with a solid 12 to 13-second period. That’s a serious amount of water moving, with combined energy rocketing up to 3861 and 4722. But the wind is howling onshore at 19 mph. That’s a dangerous, messy, blown-out beast. Only for absolute experts, and even then, it’s a kite-surfing setup, not a paddle-surfing one. Pass.
Things finally settle down on Tuesday the 8th. This is our standout window. The morning brings a glassy, 8ft WNW swell with a 10-second period and a combined energy of 963. The wind is dead calm, glass. This is the kind of morning you dream about. The wave quality is marked as “very good”. It’s solid intermediate size, but the clean conditions will make it a dream. Crowds are possible at Dumps, so get there early.
The good news keeps coming. Towards the end of the run, on Wednesday the 16th, we have another cracker. Morning sees a clean 6ft WSW swell, combined energy of 836, with a light cross-off breeze. The forecast says “very good” conditions. Then on Thursday the 17th, the morning goes glassy again with a 5ft WSW swell. It’s a bit smaller, but will be super clean. Both of these are in the second week, so treat them as promising but less certain.
For the rest, there’s a lot of cross-on chop and marginal conditions. The first week is a bust, and there’s a gap of poor surf from the 9th to the 15th, with only a few small windows of questionable conditions. But that Tuesday the 8th and the following week’s clean mornings are the real gems.
Rusty signing off.
