When to go
Denia and Xabia/Javea are usable yearround, but the easiest water window is May to October.
Best overall window
Good mixedtrip weather, warming or stillwarm sea, more manageable coves and better hiking comfort. Sea often ranges from about 18°C in May to 22°C in October.
Outside that window
School Holiday Crowds.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.

| Overall | Overall - Jan: More variable | Overall - Feb: More variable | Overall - Mar: More variable | Overall - Apr: More variable | Overall - May: Best | Overall - Jun: Best | Overall - Jul: More variable | Overall - Aug: More variable | Overall - Sep: Best | Overall - Oct: Best | Overall - Nov: More variable | Overall - Dec: More variable |
These regional shifts apply only to the selected scope.
| Area | Best months | Why it changes |
|---|---|---|
| Denia, Les Rotes and Cabo de San Antonio | May to October, with September to early October easiest | The cape is exposed to north and northeast conditions. Main caution: Wind Exposed Departures. |
| Xabia south coves, Portitxol and Granadella | June to October for easy snorkeling | Sheltered coves can feel easier than the cape, but July and August access pressure is intense. Main caution: School Holiday Crowds. |
These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
