The Lowdown
Alright folks, Rusty here. Let's get into it for 13th Ave South Surfside.
Honestly, the next week and a half is a bit of a flat spell. We've got a solid stretch of small, weak energy coming in with a lot of onshore or cross-shore wind messing it up. The water is a warm 83°F, which is about average for this time of year, so at least it’ll be nice to sit out there waiting for a set that never really comes.
Monday the 14th starts off tiny with 1ft of SE swell and a 9-second period. The combined energy is a measly 20, so really weak. The morning is cross-off from the north but it's still just too small. By afternoon, it goes glassy with a light easterly, which is a beautiful thing to see, but again, the swell just isn't there.
Tuesday the 15th through Thursday the 17th is more of the same story: small E swell between 2ft and 3ft, periods short at 6 seconds. The wind is mostly cross or cross-on from the east, so it's chopped up and weak. The combined energy tops out at 71 on Tuesday morning, still nothing to get excited about.
Friday the 18th and Saturday the 19th are even smaller. We're talking 1.0ft to 2ft, and the energy drops right off to single digits. A glassy window Saturday morning with 1.0ft SE swell, but that’s it.
Sunday the 20th is tiny with 1.0ft SE swell and a slight improvement in period to 8 seconds. Wind is cross-off from the SW in the morning, but it’s still just ankle-snappers.
There's a long quiet gap here until the end of the month. The next hint of something happens on Friday the 25th with a jump in swell to 3ft - 4ft from the east. The combined energy hits 310 on Friday afternoon, which is moderate, and the period is 9 seconds. But the wind is onshore from the south with risk of thunderstorms, so it'll be choppy and messy.
Saturday the 26th looks similar: 3ft to 4ft E swell with moderate energy (129 to 330), but again, onshore wind and storms ruin it.
Finally, the standout. Sunday the 27th is the best bet in this whole forecast window. The morning has 4ft E swell with a 8-second period and combined energy of 157. The wind is cross-off from the north, so it’s clean. The afternoon gets even better: 5ft E swell, period dropping to 7 seconds, but energy jumps to 212. The wind goes light and cross-off from the north, making for clean conditions. The swell direction is SE, which is the optimum for this spot. It’s not huge, but given the rest of the run, this is the day. Expect it to be a bit fat with the short period, but at least you’ll get a few rides. Crowds can be an issue here sometimes, so get in early.
Monday the 28th drops back down to 2ft - 2ft with clean conditions in the morning and glassy in the afternoon, but the energy is gone.
That’s it. A long, slow grind with one decent Sunday on the 27th to aim for. Stay patient.
