The Lowdown
Alright folks, Rusty here. Let’s get straight into it for Poldhu Cove. We’ve got a long stretch ahead, and honestly, it’s a bit of a waiting game for the first ten days or so. The surf is just too small to get excited about, with waves barely creeping over 1ft most days, and the energy readings are all in the low double digits, sometimes even single digits (41 down to 7). That’s marginal, flat-leaning stuff. The water is a notable 65°F for now, which is 4°F warmer than usual for the time of year – that’s a proper treat if you’re just paddling around.
We go through a long gap with no real recommendations until we hit the last few days of July. The early part of the month is a write-off for surf.
The first real flicker of life shows up on the morning of the 27th of July. We get a clean 2ft swell from the west, with a period of 9 seconds. The wind is a light offshore from the northeast at just 3 mph, making for clean conditions. The energy is still modest at 69, but it’s surfable. It’s not a standout, just a hint of something.
The real standout, and the only one worth marking on the calendar, is the morning of the 30th of July. The swell jumps to 6ft from the west, with a long period of 12 seconds (groundswell) and the energy reading is a strong 915. That’s some serious juice. However, the wind is a moderate cross-onshore from the WSW at 12 mph, which will put a chop on the surface. That size, with that period, is going to be a proper paddle, and it’s looking more interesting for the kite crew than the paddle crew at a beach setup like this. The afternoon gets worse with onshore winds. The next day, the 31st, is similar with 6ft swell and onshore winds, so it’s a messy, powerful window for experts only.
If you’re patient, that one morning on the 30th is the best on offer, but it’s gonna be a grunt. Poldhu Cove is listed as *inconsistent*, so this blank run is not unusual for the area.
