The Lowdown
Alright, let’s look at Indian River (Southside). Honestly, it’s been flat or near flat and it’ll stay that way for a long while here.
There’s a big dry spell ahead of us – through this week and into the middle of next week the surf is tiny and blown out. A few knee-high pulses but nothing you’d wet a wetsuit for. Wind’s mostly onshore or cross-shore, and the water’s sitting at 77°, which is a few degrees warmer than usual, about 5° above average. Feels like bathwater.
The first real chance to paddle out is Monday, September 21st, in the morning. We get a little NE push with waves around 4ft, a light cross-offshore NW breeze, and clean conditions. It’ll be weak though – combined energy is just 62 (weak). Surfable, but very ordinary.
Then the wind picks up hard from the NE on Tuesday the 22nd – strong breeze, messy. No thanks.
The interesting part, for experienced surfers only, comes late in the outlook. By Wednesday the 24th of September, the swell builds in the morning – chest to head high at 5ft, with a cross-offshore WNW wind. The energy is moderate (297). Still lumpy conditions and the period is short, so the waves will be sectiony.
Thursday the 25th of September – now we’re talking serious size for experts – around 8ft to 8ft by afternoon, with a cross-offshore SW wind and clean conditions. Short period, but serious energy (572 to 730). That kind of size on a beach/jetty setup will be more fun for the kite surfers than paddle surfers. If you’re an expert, the Friday morning on the 25th might offer a few clean lumps, but it’s marginal.
So there you go: a long flat spell now, nearly two weeks. The best is the morning of Monday the 21st with small clean waves. The bigger stuff at the very end is only for experts and the quality is uncertain. Don’t hold your breath.
Rusty.
