Best Times of the Year to See Dolphins Near Longboat Key

If you love dolphins and want to see them up close in the wild, Longboat Key is one of the best places to go! This beautiful barrier island near Sarasota, Florida, is a prime spot for dolphin sightings all year long. But if you want the best chance of spotting these amazing creatures, some times of the year are better than others. Let’s dive into when you should visit to catch dolphins in action!

Dolphins can be seen near Longboat Key all year thanks to the warm waters of the Gulf of Mexico. However, their activity changes with the seasons. Here’s what you can expect:

Spring (March – May)

Spring is one of the best times to see dolphins! As the water warms up, dolphins become more playful and active. This is also when schools of fish move into the area, giving dolphins plenty to hunt. Mornings and early afternoons are the best times to go, as the water is usually calm.

Summer (June – August)

Summer is a popular time to visit Longboat Key, and it’s also great for dolphin watching! Dolphins love the warm water and are often seen in small pods, leaping and playing. However, since afternoon thunderstorms are common, it’s best to go in the morning when the water is calm and the sun isn’t too intense.

Fall (September – November)

Fall is an underrated season for dolphin lovers. With fewer boats on the water, dolphins seem more relaxed and curious. The weather is still warm, and the water remains clear, making it easy to spot them. If you’re looking for a quieter experience, fall is a great time to visit.

Winter (December – February)

Even though temperatures drop a little in winter, dolphins are still around! In fact, this can be one of the calmest times of the year for dolphin watching. With fewer tourists and boats, you’ll have a better chance of getting an up-close sighting. The water is often clearer, making it easier to see dolphins swimming just below the surface.

Best Time of Day to See Dolphins

While dolphins can be spotted throughout the day, there are better times to see dolphins better:


  • Morning (10 AM – Noon): Dolphins tend to be most active in the morning when the water is cooler and calmer.
  • Late Afternoon (2 PM – Sunset): Another great time! As the sun starts setting, dolphins often come closer to shore to feed and play.

If you book a tour during these times, you’ll have a much better chance of seeing dolphins jumping and playing in the waves!
