Regional timing around El Hierro
These regional shifts apply only to the selected scope.
| Area | Best months | Why it changes |
|---|---|---|
| La Restinga and Mar de Las Calmas | September to November | The sheltered south is the main dive and freedive planning zone, with autumn favored for warm water and cleaner surface management. Main caution: Same-day route swaps become more likely when weather builds. |
| North coast and El Golfo natural pools | April to June and September to October | Charco Azul, La Maceta, and other lava pools can be superb, but Atlantic swell matters more than the calendar. Main caution: Crossings and exposed sites can feel rougher in this stretch. |
