The Lowdown
Alright, let me tell you how it’s looking for Indian River (Northside). Gotta be straight with you—this stretch is running flat and ordinary. The first real surfable swell doesn’t show up until Monday the 21st of September. Before that, it’s a whole lot of tiny, weak slop and poor conditions. The combined energy stays well under 100—mostly down around 10 to 40—so there’s nothing to get excited about for over a week.
On Monday the 21st, things finally change. We get a pulse of swell coming from the ENE at 6 ft, with a short period of 7 seconds. The combined energy jumps to 328 (moderate wave energy) and early morning wind is offshore from the WSW at 15 mph, making for clean, lined-up surf. This is the standout window—it’s the only time the conditions line up. The water temp is about average for this time of year, nothing unusual. The break is consistent but can get crowded often, so you won’t be alone.
That morning on the 21st is your call. After that, the wind turns messy on Monday afternoon and the swell fades through Tuesday with cross-onshore winds. By Wednesday the 23rd, it’s back to weak, small surf with energy dropping below 100 again. Thursday the 24th sees another larger pulse of 3 ft from the SE with a 13-second period and energy at 364, but the NE cross-onshore wind at 15 mph ruins it for paddle surfing—better for kites than a shortboard.
So, one morning to aim for. Mark it.
