Is Arenas Surf Forecast and Surf Report

Alright, grab your coffee, let’s have a look at the charts for Is Arenas.

Honestly, mate, it’s a tough run ahead. The next 16 days are mostly flat or junky, so you’re gonna need patience. We get one little pulse that might be worth a paddle if you’re keen, but it’s a short window and then it’s back to the doldrums.

The best chance you’ll get is on Monday, July 27th, the first day of the forecast. Early morning, it looks glassy with a clean 4ft swell rolling in from the northwest. The period is around 8 seconds, so it’s a bit of a short-period wind swell, not a groundswell with real grunt, but the combined swell energy sits at a moderate (237). The water is feeling very warm—82° with an anomaly of 5°, which is much warmer than normal for this time of year. With glassy conditions and that size, it’s the pick of the whole run for an intermediate surfer.

The only break in the mix here is Is Arenas, a sandbar setup that’s inconsistent, so you gotta be ready to wait for the sets. It can get crowded, which makes sense if you consider how little else is on offer. The optimum swell direction for this spot is from the NNW, and we have a NW swell, so it’s close but not perfect. That Monday afternoon sees the wind switch onshore from the NW at 12 mph, chopping it up, so the session is strictly a morning mission.

After that, Tuesday the 28th still has a little waist-high 4ft swell in the morning with glassy conditions, but the energy drops to weak (109) and the period is a short 7 seconds. It’s surfable but ordinary, nothing to get excited about.

Then we go into a massive lull. From Wednesday the 29th of July all the way through to Tuesday the 11th of August, the swell just drops off a cliff. Most days show combined energy in the single digits or low double-digits, and wave heights rarely break 2ft. The wind is often glassy or light in the mornings, but there’s simply no swell to work with. Even the bigger days in that stretch—like Thursday the 6th of August morning with a 2ft swell—are still too small and weak to bother with.

Late on Tuesday the 11th of August, we get a flurry of activity in the afternoon: a 4ft swell from the WNW with an 8-second period and a combined energy of 265. That’s interesting on paper, but it comes with an onshore wind (12 mph from the NW) and the forecast calls it poor, so don't count on it being clean.

Overall, if you’re determined, hit it early on Monday the 27th. Otherwise, leave the board in the garage—this stretch is more suited to a beach walk than a paddle out.

Stay salty,
Rusty
