Seasonal Patterns and Timing
Migration and Peak Months
Dolphins arrive in late spring as waters warm, remaining through autumn when cooler temperatures prompt southward movement. July and August typically offer the highest likelihood of sightings close to shore.
Weather and Tide Influences
Onshore winds and incoming tides often concentrate baitfish, which draws dolphins closer to beaches. Overcast, mild days can sustain activity longer into the evening than bright, windy conditions.
