November trade-offs

- ↓Sea conditions less stable: snorkelling visibility reduced and dhow trips occasionally cancelled
- ↓Beach bars and some watersports operators reduce hours or close on prolonged rainy stretches
September trade-offs
- ↓Trade winds beginning to ease — kite surfing less consistent than July–August
- ↓Short rains start to build from late September in some years — an early October risk to consider
