Alright, Rusty here. Let’s have a look at what’s on the table for the next couple weeks.
Well, I gotta be straight with you—this is a pretty grim stretch for Devonport Rivermouth. We’re looking at a real dry spell. The first real standout doesn’t come until Thursday the 16th of July, which means we’ve got a long gap of over a week with absolutely nothing worth paddling out for. From Saturday the 4th all the way through to Monday the 13th, it’s all tiny, weak junk and poor surf conditions. Just no energy or shape.
Even when there’s a little bump in size around Sunday the 12th and Monday the 13th, the period is super short (6 seconds) and it’s cross-onshore with a chop. That’s more of a kite-surfing setup than a paddler’s wave. Not for us.
Now, Thursday the 16th of July morning is where it finally gets interesting. We see a clean 6ft swell from the NW, with a period of 8 seconds. The wind is light from the WSW, almost glassy, keeping things clean. The combined energy is a solid 365 – moderate, but with that height and clean conditions, it’ll be fun for intermediate surfers. This is the standout of the whole outlook, no question. The water temp is about 56°F, which is pretty normal for this time of year, so don’t forget the booties.
Friday the 17th of July morning also has potential—7ft from the NW with period 8 seconds, which is getting into expert territory. But there’s a light cross-shore wind and the energy is strong at 671, so it’ll be powerful. Not for the faint-hearted, and the wind might put a little crinkle on the face. Still, a good option for those who know what they’re doing.
After that, it drops off again quickly into tiny, weak leftovers for the weekend and beyond. So, if you’re after a wave, Thursday the 16th is your best bet—and your only real bet.
Stay patient, check the charts, and see if anything shifts. It tends not to stay this quiet forever.
Rusty.
