Alright folks, Rusty here with a look at the waves over the next couple of weeks.
We've got a mixed bag coming our way. The main event is Trestles (Uppers), a reef and point setup that's exposed to the W swell. Water temps are running about average for this time of year, so no wetsuit surprises. The first few days are a bit of a struggle, with small, wind-affected swell.
Tuesday morning the 7th kicks off with a clean 4ft SSW groundswell, period a long 18 seconds. The combined energy is moderate at 853, and with just a light onshore breeze, it's fishable. But the tide and consistency are questionable, so don't expect perfection. By afternoon, the wind swings cross-onshore and it gets choppy.
Wednesday the 8th holds similar 3ft to 4ft SSW swell, but the wind stays messy from the W, keeping things lumpy. Thursday the 9th is more of the same, with light cross-onshore wind and weak, junky waves. Friday the 10th through Sunday the 12th sees the swell drop further to 3ft-3ft and the conditions go from marginal to poor. Honestly, not much to get excited about.
We hit a real dry spell from Monday the 13th through Wednesday the 15th of July. Swell drops to 1ft, combined energy is weak (under 250), and the wind keeps it onshore. This is a stretch of 4-5 days with really not much happening. Even Thursday the 16th is a write-off with a 1ft SW groundswell and a moderate cross-shore wind.
There’s a tiny flicker on Friday the 17th, a 2ft SW swell with a very long 19 second period. The combined energy is weak at 264, but that period is something. The wind goes light from the S, so it might just hold shape for a sneaky session. It's a reach, but for the dedicated.
The real standout comes out of nowhere. Saturday the 18th of July rolls around and we see a bump. Morning brings a clean, long-period 3ft SW groundswell (18 seconds) with combined energy of 437. The wind is light from the SSW. It’s not huge, but it’s the best we’ve seen in a week. Sunday the 19th is even better. The swell picks up to 3ft SW, period 17 seconds, energy jumps to 512 in the morning and builds to 658 in the afternoon. The wind stays light cross-onshore, but for Trestles, that's workable. This is the pick of the period. It's still small, but the consistent groundswell and clean conditions make it a proper surfable day.
Monday the 20th offers a 4ft S swell, but the period is a short 12 seconds. The energy is moderate at 779, but that shorter period and cross-onshore wind will make it sectiony and weak. Not a stand-out. The rest of the week from the 21st onward returns to marginal 3ft-3ft SSW swell with light wind.
Overall, keep your expectations tempered. The first week is a write-off, but that weekend of the 18th and 19th of July is your best bet for a proper paddle.
