The Lowdown
Right then, let's have a look at what's on the cards for Playa de Gaztetape. The water's sitting at a balmy 73°, which is much warmer than usual for this time of year—a nice little bonus for the early sessions.
To be honest, the first few days are a write-off. Tuesday's got a sloppy little cross-on breeze and tiny, weak waves (combined energy of only 127), so don't even bother. Wednesday and Thursday stay poor with onshore winds and choppy conditions, even though the swell energy picks up a bit. There's a sniff of something on Friday the 18th morning with clean cross-off winds and a tiny 3ft NW swell (energy of 225), but it's nothing to get excited about.
Now, hold onto your board, because Saturday the 19th morning is the real standout. We've got a solid 8ft NW groundswell rolling in with a long 13-second period and glassy conditions off an ESE breeze. The energy is pumping at 1756 (strong to very strong), and the water will be clean as a whistle. This one's for experienced surfers only—that size and power is not for the faint-hearted. It'll be a proper session.
Sunday the 20th is still very good, with glassy mornings and a clean 5ft NW swell, period around 12 seconds (energy of 586). Crowds are possible here, so get in early. Monday the 21st morning looks even better on paper—calm winds, glassy surface, 5ft NW groundswell (period 12 seconds) and a combined energy of 690. Expect very good, clean waves. Tuesday the 22nd stays clean and fun, with 4ft waves and glassy conditions both sessions.
The following week gets patchy. Wednesday the 23rd is small and ordinary, but Thursday the 24th morning fires up again. You'll see a clean 6ft NW groundswell with a 13-second period and glassy conditions—energy of 991. That's another top morning for those who can paddle out. After that, we drop back into smaller, cleaner but less powerful surf through to the end of the month, with a few glassy windows on the 25th and 26th.
Looking way ahead, Wednesday the 30th of September morning has a promising 6ft WNW groundswell, period of 11 seconds and glassy conditions (energy of 799)—expect very good surf again, but that's a long way out, so keep an eye on it.
Overall, the best on offer is Saturday the 19th morning for the big, clean groundswell, and Monday the 21st morning for slightly smaller but still excellent conditions. Don't sleep on Thursday the 24th morning either.
