Alright folks, Rusty here. Let’s get straight into the local picture for the next couple of weeks.
Right off the bat, I’ve got to be real with you – this is a tough one. The forecast is pretty much a write-off for the entire 16-day period. We’re looking at a long, dry spell with no real surf on offer. The first record is for Monday the 13th of July, but even that’s a non-starter.
The only spot in the game is Devonport Rivermouth, a point/river setup that’s inconsistent and can get crowded. The water temp is sitting at 56°, which is about average for the time of year, so that’s not giving us any excuses.
Monday the 13th sees a 12ft swell from the NW, but with a strong 25 mph cross-wind, it’s a total mess. The combined energy is high at 1904, but that’s just raw power without any finesse – think closeouts and windslop. Not for the faint of heart, and way too big for beginners.
From Tuesday the 14th onward, it’s a slow bleed. We get a tiny 5ft swell on Tuesday morning, but with a short 7-second period, it’s weak and lacking any punch. The winds are a bit better, but the surf quality is still poor. By Wednesday the 15th, we’re down to 4ft, and it just keeps dropping.
From Thursday the 16th all the way through to the end of July, the swell is tiny – often under 2ft – with combined energy readings in the double digits or low triple digits. These are flat or near-flat conditions. The period jumps around, but with no height to back it up, it’s meaningless. You’ll get some glassy mornings on the 18th and 20th, but that’s just a flat lake.
There’s a gap of about two weeks with no real surf to recommend. The 28th of July brings a 0.3ft swell and a 16 mph cross-wind – that’s not surf, that’s just a windy day at the river mouth.
Look, the place is inconsistent, and this blank run is unfortunately normal for the area. Keep your gear waxed, but don’t bother checking the forecast for a while. Things can change, but right now, there’s nothing to ride.
Rusty.
