The Lowdown
Alright folks, here’s the skinny on Indian River (Southside) for the next 16 days. It's a bit of a slow cooker, so don't expect any heroics. The water's running about 2° warmer than usual for the season, so that's a bit different.
For the first stretch, we have a few days where there's just nothing doing. It stays small and poor. The first real glimpse of something happens late on Sunday, the 16th. A south swell shows up with some moderate energy (56 combined), pushing a 1.1m wave at 5 seconds. It's got clean cross-off winds, but there's a chance of thunderstorms. It's surfable, but it's hardly a classic.
The swell dries up again, and we're looking at another quiet patch until the morning of Wednesday, the 19th. That’s when a SE swell builds to 0.9m, with a longer period of 11 seconds and the most energy we’ll see all period (247). The winds are light and cross-onshore, so it will be a little crinkled, and it’s looking marginal at best.
After that, it's pretty much a desert. We see swells hanging around 0.3m to 0.7m, but the winds keep messing things up. There are a couple of clean offshore mornings, like the 22nd, but with such little swell, it's not worth suiting up for. A little bump on the 24th to 0.7m from the south is there, but onshore winds chop it up.
Bottom line: this is a tough 16 days. There are no real standouts. If you absolutely have to get wet, the 19th is your best bet, but even that's a stretch. This break is fairly consistent, so stretches like this usually don't last too long. Forecasts can change. Keep checking back.
