Best Time to Snorkel in Hawaii
The beauty of Hawaiian snorkeling lies in its year-round accessibility. However, there are a few considerations to make your experience even better:
- Year-Round Conditions: While snorkeling is possible in all seasons, winter months (November to March) bring higher surf on the north-facing beaches, which may affect visibility and conditions.
- Ideal Months: Summer (May to September) generally offers calmer waters and optimal visibility.
