Visit Florida

St. Petersburg is located just across the bay from Tampa along the coast of West Central Florida. Because the city is surrounded by water, it helps keep temperatures more moderate in the summertime and just a bit warmer in the winter, giving St. Petersburg an overall average high temperature of 82° and an average low of 66°.

The weather usually cooperates in March for the Firestone Grand Prix, a world-class motorsport event that roars into town, but you may have to dodge some raindrops the following months if you take in a ballgame at Tropicana Field to see the Tampa Bay Rays play ball.

Wondering what to pack? Shorts and sandals are always in style and a great choice if you're on the beach side of the city, but visitors to downtown may want to dress in resort casual wear to fit in. Of course, don't forget to pack your bathing suit if you're visiting St. Pete Beach. While Gulf of Mexico temperatures can be quite chilly in the winter, sunbathing is usually not out of the question.

The Atlantic Hurricane season runs from June 1 through November 30, with August through October being the most active months. St. Petersburg, like most of Florida, has not been affected by a hurricane in more than a decade. The last storms were in 2004 and 2005. Hurricane Frances hit the area on September 5, 2004, and just three weeks later, a stronger Hurricane Jeanne blew into town. A year later it was Hurricane Wilma that battered the area.
