Sanibel Island has a subtropical climate due to the warm Gulf Stream and its position just north of the Tropic of Cancer. The weather while generally breezy, hot and humid, does get occasional cold fronts, bringing frost and temperatures around freezing. In addition, the waters surrounding the island dip into the upper 60s in winter, and only reach the upper 70s-low 80sF in spring and fall. The Gulf waters reach the upper 80sF by summer, which can bring hurricanes and tropical storms late in the year, as well as afternoon thunderstorms nearly every day during summer.
Sanibel is not a stereotypical "Spring Break" type of destination. Its primary attractions are its birds, seashells, and sunsets, and many families travel here for a quiet getaway.
Sanibel is flat, long (12 miles), and narrow (3 miles at its widest). On the west, its beaches face the Gulf of Mexico. To the east, Sanibel borders Pine Island Sound and San Carlos Bay. The majority of the waterfront on the Sound is part of J.N. "Ding" Darling National Wildlife Refuge, including the calm waters of Tarpon Bay. The beaches are the main attaction, with warm and calm, emerald waters and gorgeous sunsets. The sand at the beach in Sanibel is not as soft and white as the Gulf Coast beaches typically are. Due to the natural setting and shelly coastline, the sand is typically darker and more rough, comparable to the sand on Florida's Atlantic coast. Still, this does not take away from the beauty of the beaches in Saibel.
People looking for well-groomed white-sand beaches on Sanibel may be disappointed. The beaches are less maintained and more natural than in many locations. Seashell collectors will be pleasantly surprised by the density of seashells.
The peak travel season in Sanibel is January through April. Southwest Florida has some of the nation's mildest weather during this time, making this particular area appealing to winter-weary travelers. September and October are the island's quietest months, with some businesses shutting down for several weeks of the year.
Summers in southwest Florida can be oppressively hot and humid, but during the other months of the year Sanibel is a mild and pleasant environment. Even in the summers Sanibel's ocean breezes can eliminate some of the stifling heat.
Most travelers arrive by automobile, crossing the Sanibel Causeway (a one-way toll of $6 applies at the time of this writing). There are no airports on the island and no ferry service from the mainland.
Sanibel Island is less than 25 miles from Southwest Florida International Airport. Follow Daniels Parkway west to Summerlin Road, then Summerlin Road south and west to McGregor Boulevard, which leads to the Sanibel Causeway.
Posted speed limits are enforced by local police, who will remind you why you have come to Florida's islands. Most roads will have limits of 35 MPH or less, through both residential areas and protected wildlife zones. Beware of the infamous double stop signs of Sanibel. They are posted like that because they are often missed. Be particularly careful to mind the speed limit at night. There are not many roads on the Island and at night there is virtually always someone watching them. Watch for pedestrians and cyclists.
On the eastern half of the island, the main road through the city is Periwinkle Way. A variety of side streets connect this road with the beaches, shops, restaurants, and lodging on the island.
On the western half of the island, the main road is Sanibel-Captiva Road, or "San-Cap". Fewer roads connect to this one, which is bordered by protected lands on both sides for much of its length. At the end of San-Cap where the two islands meet at Blind Pass, this area is called "Santiva", a portmanteau of Sanibel and Captiva.
Running parallel to both these roads, along the southern shore of the island, is Gulf Drive.
There are 22 miles of cycling paths on Sanibel. With no hills to speak of, cycling can be a rewarding way to see the island. However, shops and restaurants are located more than two miles from most lodging locations. Nighttime riding requires caution but is enjoyable with high quality bike lights. Paths and roads are not illuminated with streetlights, so riding after dark requires a white front light and a red rear light. Numerous local businesses rent bicycles, and some hotels/inns will have bikes for their guests to use. Remember to bring water and sunscreen and obey all traffic laws.
The gorgeous naturalized beaches covered ankle deep in beautiful shells, sponges, driftwood, sand dollars, and so on. Shells cover a great bit of the sand, beach and ocean grasses and somewhat "wild looking" plants, seaweeds and aquatic plants are to be found between the homes and the water's edge. These are not "weeds," and this is not a "dirty" beach. It is a naturalized area, and Sanibel and Captiva Islands are making every attempt to keep these beautiful islands in their natural state.
The island is lush with bouganvellia, and other brilliantly colored flowers and shrubs nearly all year long. This is definitely a sub-tropical climate. Tiny chameleons scurry about (even in and out of restaurants) and you may see lots of cute, tiny tree frogs stuck to your condo door when you come home at night! Bring insect repellant with DEET for the sand flies (also called midges and "no-see-ums.") You literally cannot see the "no-See-ums" and they come right through the screens on the balconies and lanais. They may be virtually invisible to the naked eye, but you'll see the bites later. Some folks are driven crazy, others do not get bitten at all.
Sanibel is mostly known as an ecological destination. Bird watchers and shell collectors make up the majority of the island's visitors each year.
Shells, Sanibel Captiva Handbook, sharp fashions, beautiful jewelry, decorative "beachy items" and all kinds of quality merchandise. A full size grocery store ("Jerry's") holds court in one of the malls. Lavish decor outside includes macaws, parrots, Mynahs, cockatoos. This shopping "complex" consists of a combination large grocery and quality yet affordable souvenir store, as well as a specialty liquor store and a few other shops and boutiques.
You will not find any fast-food chain restaurants on Sanibel, other than a single Dairy Queen which received an exemption to the strict laws passed to preserve the island's special charm.
The oldest and largest grocery store and hardware outlet is in Bailey's Plaza. The Baileys are one of the original island families and the store is still managed by family members. You also can pre-order groceries for pick up or delivery to your rental unit through Bailey's General Store. There are other stores in the plaza worth investigating. Bailey's also features a great Coffee Bar and a Movie Kiosk, where you can rent a movie for the night. Also located in Bailey's Plaza is The Grog Shop Liquor Store, they offer a huge selection of fine wines, beer, liqueurs, and cigars at very reasonable prices. The only walk in humidor on Sanibel is located in The Grog Shop.

Although there is one "chain" on the islands, with the rest of the accommodations being small-to-medium townhome or condo complexes, each one prettier than the next. Most all have outdoor, (or indoor/outdoor covered) pools, patios and grills,and some of the largest have tennis courts, clubhouses, putting greens, etc. If you want a constant ocean view, be clear about it when making reservations. Lots of townhome and condo complexes are across from the beach. Still just a hop, skip and jump from the water, but unless you spend a lot of time on the beach itself all day, you'll miss the view! Most private rental homes are across the street from the beach or on the inner parts of the island.
Dogs and cats are allowed in some (but not many) of the condo/townhome complexes. Dogs may be on the beach if on leash. All condos and townhomes are family-friendly.
