The Lowdown
Hey, Rusty here. Let’s be straight – the next 16 days at Is Arenas are a tough watch. This sandbar break is inconsistent at the best of times, and the forecast is mostly flat or messy. The one real standout lands on Tuesday, July 28, morning. That’s the pick of the bunch.
The first little window shows up Monday, July 27, morning with a 4.3ft NW swell (8 secs, 237 combined energy) and a light cross-on breeze. The water is 81°, a full 4.5° warmer than normal – that’s genuinely unusual for this time of year. But the wind is cross-on, and the period is short, so it’s only marginal.
Tuesday, July 28, morning is where it’s at. The swell drops to 3.6ft from the NW (7 secs, 109 energy), but the wind goes glassy – dead calm. That’s a major bonus. The waves will be clean and lined up, even if the energy is modest. This is the best session on offer, no question.
Then there’s a long, dry gap. From Tuesday afternoon right through to Saturday, August 8, it’s all poor surf – tiny, weak, or onshore. The only other flicker is Sunday, August 9, morning. A 2.6ft NW swell (7 secs, 62 energy) with a cross-off breeze that keeps it clean. Small, but surfable. After that, the rest of the window fades out to nothing.
So, to sum up: Tuesday morning, July 28, is your chance. Glassy, waist-high, and warm water. Don’t expect much else. If you’re desperate, Sunday, August 9, might give you a few clean little ones. But overall, it’s a lean spell.

Information about the Is Arenas Surf forecast
The above surf forecast table for Is Arenas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Is Arenas can be found by selecting the local surf guide option on the grey menu. Our Is Arenas surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Is Arenas) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Is Arenas may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
