The Lowdown

Alright folks, Rusty here. Let's get into it.

We're looking at Trestles (Uppers), a reef and point setup that's very consistent and exposed to the west swell. The water temp is about average for this time of year.

Alright, the first few days have some waist to chest high swell around, but honestly, the conditions are a bit of a letdown. The wind is mostly onshore or cross-onshore, which is going to mess with the shape. The wave energy is still pretty meaty, with readings around 1122 (moderate to strong), but the wind just isn't playing ball for clean surflines. The 18-second period from the south-southwest is a proper long-period groundswell, which is great for a point break like this, but the onshore wind is a killer. It's a tough call to paddle out.

Monday the 27th of July sees a morning breeze from the south-southwest at 6 mph, onshore, and a 4 ft swell. It's marginal. The afternoon is much the same. Tuesday the 28th is a bit more challenging with the cross-onshore wind making it choppy. The window looking good isn't really opening up.

The standout window is actually now. Thursday the 30th through Friday the 31st of July has the best combo of size and period. We're seeing a 6 ft swell from the south, with a 14-second period on Thursday morning and 13 seconds on Friday. The wave energy is still in the 1000s, which is solid. The wind is light on both mornings, but the swell direction is from the south, not the ideal west. It's not the cleanest, but it's the best we're going to get. The wave energy is 1122 on Thursday morning and 1041 on Friday morning. The break is very consistent, but it's also always crowded, so expect a pack.

After that, it all goes quiet. From the 1st of August right through to the 11th of August, the swell drops away. We're looking at waves between 1 ft and 3 ft. The wave energy drops to three-digit numbers, and the forecast is dominated by poor surf conditions. This is a long, flat spell with no real options. A blank stretch like this is more common for the area when the summer swells don't align.

So, for the whole 16-day window, Thursday and Friday of this week are your best bet, but don't expect perfection. The rest is a write-off.

Rusty.
