Of course winter and spring constitute high season in Southwest Florida, and Sanibel and Captiva island fall into that mold. Yet there’s something about summer on the islands. Something more intimate and personal. Something more authentically Floridian.

So why plan a summer trip to Sanibel and Captiva islands? For one thing, the most practical thing, rates at ‘Tween Waters Island Resort & Spa and Castaways  Beach & Bay Cottages on Captiva Island; and West Wind Island Resort and Beachview Cottages on Sanibel dip drastically from high season, plus other incentives make it an especially attractive time of year budget-wise.

For instance, right now, all four resorts are giving away a free night when you book three. They are sweetening the deal with $100 in reward coupons and, in the case of ‘Tween Waters and West Wind, dining credits. PLUS, if you book by June 30, you score two free logo Tervis tumblers (call-in reservations only, mention “tumblers”).

The newly remastered Old Captiva House

Speaking of dining, summer means no lines, no crowds, no waiting at your favorite resort restaurants, such as Old Captiva House at ‘Tween Waters and Normandie Seaside Cafe at West Wind Island Resort. Likewise, on the beach, it’s easy to find a spot  you won’t be sharing with anyone but the birds of summer.

Watch for manatees in the summer.

Bayside, watch for manatees, who mate this time of year close to shore. They favor the little cove on the south end of ‘Tween Waters’ bay shoreline. Get out on a paddleboard or kayak to see more of the islands’ wildlife come alive. Baby birds are hatching. Gigantic sea turtles are laying eggs, and adorable gator hatchlings are crawling out from their nests.

Not only fauna, but flora gets showy in summer. It’s that time of year when mangoes blush with serious, ponderous sweetness. Poinicianas, oleanders, crape myrtles, bougainvillea, and hibiscus blossom. Late afternoon rains bring the islands to their lushest.

Summer: It’s a season ripe for taking life easy, waterside, with a cold drink and a good novel. The Sanibel Captiva Beach Resorts have your lounge chair and cocktail ready. Just add sunscreen.
