The Lowdown
Alright folks, Rusty here. Let’s level: the next 16 days at Indian River (Southside) are a total flat spell. The combined swell energy barely gets into double digits for the first week, topping out around 50 (moderate on the low end), but none of it has any grunt. Water temp is about normal for this time of year.
From Tuesday the 8th all the way through the second week, there’s nothing worth paddling for. Swell heights bounce between 0.7 ft and 4 ft, mostly from the east or southeast, with periods ranging from a choppy 4 seconds up to a 10-second groundswell on the 13th, but even that’s only 1 ft. Winds are mostly cross-shore or onshore. There are a few clean moments—like Thursday morning the 10th with a light offshore breeze at 12 mph—but the waves are tiny and ratty. The score is zero the whole way. Even Monday the 21st with glassy conditions and 2 ft from the south just doesn’t have the power.
No standout session here. The closest is Thursday afternoon the 10th: 3 ft from the south at 6 seconds with a light offshore wind, but the rating was a 1 out of 10—surfable but very ordinary. For a spot that’s exposed to SSE swell, the direction never lines up with any energy. Crowds are “often” at this break, but trust me, nobody’s out for this.
If you’re into kiting, those afternoons with 15-18 mph cross-off winds and 3-4 ft waves on the 16th and 19th might be fun. For paddle surfing, leave the board at home. The dry stretch from the 8th to the 23rd is about as dead as it gets.
Forecasts can flip, though. Rusty.
