The Lowdown
Right, let's have a look at what's on the table for 15th Street. It's a beach and reef setup, and it's consistent, so it's got plenty of potential. Lately, the water's been 73°, which is much warmer than normal for this time of year — feels like a bath out there.
We've got a bit of a quiet start, but don't let that fool you. The first real offering is a long-period groundswell from the SW, 17 seconds, pushing in at 3 ft on Sunday the 19th. The combined swell energy is moderate (695). The wind is onshore from the W at 15 km/h, which is going to put a bit of a bump on it. It's just "marginal" — you'll find a wave, but it's not going to be a standout.
Monday the 20th is much the same story, with a 3 ft SW swell, still onshore wind. The energy is a bit lower (588). The following days through to Thursday the 24th are a bit of a write-off, with the swell dropping and the wind staying onshore or cross-onshore. The forecast is calling it "poor" or "marginal" at best. It's a bit of a flat spell, but it won't last long.
Then, things get interesting. Friday the 24th sees a huge jump in period — a 24-second SW groundswell. It's only 2 ft, but the energy is ramping up to 993. The wind is still a bit of a factor, but the potential is there. Saturday the 25th is similar, with a 3 ft SSW swell and a 21-second period. The energy is up to 919. The wind is light and onshore, so it might clean up a bit.
Now, the real standout is shaping up for the end of the month. On Friday the 31st of July, we've got a 5 ft S swell pushing in with a 16-second period, and the combined energy is a hefty 1626. The wind is onshore from the WSW at 15 km/h, which is a bit of a bummer, but the size and power are there. Then, Saturday the 1st of August drops a 7 ft S swell. That's getting into the expert territory, boys. The energy is 1349, and the period is a bit shorter at 12 seconds. The wind turns light and offshore from the W, so it should be clean. This is the one to circle on the calendar. That S swell is going to line up well with the optimum direction for 15th Street.
After that, it drops off again. Sunday the 2nd and Monday the 3rd of August are back to small, poor conditions with cross-onshore winds. The energy falls away to 469 and then 248.
If you're looking for the best of the bunch, it's got to be that Saturday the 1st of August. The 7 ft S swell with light offshore wind is a combo that doesn't come around often. It's going to be a big day for the crew that are ready for it. The crowds are often here, so expect a few familiar faces out.
Alright, keep it salty.
