The Lowdown
Alright, let’s put it in terms you might be more familiar with. The ocean is flat, plain and simple. For the next two weeks, we’ve got a real dry spell on our hands. There’s a couple of days where a little bump shows up, but it’s nothing to get out of bed for.
Right now, and for the next few days, it’s a total write-off. The swell is tiny, the wind is mostly onshore, and the water at Dunes Hotel (Miami) is a warm 87°F, which is a touch warmer than average for this time of year. The energy is weak, barely registering (25), and the period is a short, weak 4 seconds. It’s consistently poor. The only thing that changes is the wind direction, but it never gets clean enough to make anything of the 3ft, 2ft, or 2ft scraps of swell.
We’ll see a little shift around the 26th of July and into the 27th, with a tiny 0.3ft swell from the north-east. The wind goes light and cross-offshore in the mornings, which is clean, but that swell is so small it’s barely a ripple. The energy is practically nothing (5). This is a good time to check the tide pools or go for a swim.
That pattern of tiny, 0.3ft north-east pulses continues through the end of the month and into the first week of August. On the 31st of July we get a morning with light offshore wind from the west-southwest and clean conditions, but again, with only 0.3ft of swell and energy at 4, it’s not surfable. The 1st of August morning is glassy with a light west-northwest wind, but still, 0.3ft of swell means no rideable waves.
The long and short of it is: there’s no surf to recommend. The combined energy of all swells directed here barely cracks into double digits, and on the few days it does get to 20 or 25, the swell height is still only about 2ft and the wind is messy. It’s a real bummer, but this is the kind of blank run that happens in this area. Forecasts can change, and it never stays this poor forever, but for now, leave the boards at home.
