The Lowdown
Alright, Rusty here, and I’ve got the lowdown for the next couple of weeks.
Honestly, mate, it’s a tough stretch ahead. We’re looking at a full 16-day window starting now, and the news isn’t great for surf. For this whole period, there is nothing that truly stands out as a good wave. The forecast just shows poor surf conditions day after day with no real energy or quality to get excited about. From the very start all the way through to the end of the month, it’s a bust.
Let’s run through it. On Tuesday the 11th of August, South Beach (Miami) is tiny at 0.3 ft from the northeast with weak energy (7), and a 9 mph cross-onshore wind from the east-southeast makes it choppy. That’s your pattern for the rest of the week – flat, messy, and not worth paddling out. Wednesday the 12th and Thursday the 13th are more of the same: swell heights barely reaching 0.3 ft to 1 ft, with light to moderate southeast winds keeping it choppy. The combined energy is almost nothing, hanging around 2 to 11 the whole time.
Friday the 14th through Sunday the 16th doesn’t get better. The swell picks up a bit to 3 ft on Saturday morning from the southeast, but that comes with 16 mph winds and combined energy at 45 – still weak and poorly shaped. Even the afternoons with onshore wind offer no quality. You’re looking at cross-on winds and terrible conditions every session.
The second week is no relief. From Monday the 17th of August right through to Wednesday the 26th of August, it’s the same story. Swell stays between 0.3 ft and 2 ft, with east-southeast to east winds blowing 6 to 12 mph, almost always cross-on or onshore. The biggest energy number we see is just 37 for the morning of Wednesday the 19th, and that’s from a 1 ft swell with a 12-second period, but it’s still accompanied by poor surf conditions. It’s small, weak, and wind-affected – a total write-off.
If you’re desperate for a paddle, Tuesday the 18th morning shows a brief moment of clean conditions with a light north-northwest cross-offshore wind and 0.7 ft swell – but honestly, it’s barely a ripple. The setup here is a sheltered beach/jetty, best for beginners when it’s small, but even then, the swell is gone.
In a nutshell, if you want to surf in this region over the next 16 days, you’re out of luck. The forecast is consistently poor. Most breaks in the area tend to be like this – when the swell and wind don’t line up, you get a blank run. It’s frustrating, but that’s how it goes sometimes. Might be worth checking if the kites are flying, because for paddling, there’s nothing here.
Rusty.
