Spring (March through June) is when San Antonio starts to heat up—in more ways than one. As the doldrums of winter pass and flowers bloom, young and old alike find the city alive with festivals and activities. The local amusement parks—Sea World and Six Flags—open in late March and early April, respectively, when Texas schools are on spring break, so hotels and motels around town fill up. The first weekend in March also brings Remembering the Alamo weekend, with reenactments of the legendary battle. In April, Fiesta San Antonio, a street fair of epic proportions, kicks off 11 days of parades, fun runs, art exhibits, sales, concerts, and military displays—the city is home to both Air Force and US Army installations. The Cinco de Mayo celebration at Market Square also draws crowds.
Though October is the heavy convention season in San Antonio, the event schedule is a little lighter than spring. Cooler temps make it a great time to visit the well-appointed San Antonio Zoo, catch a San Antonio Spurs game, or take advantage of the (relatively) chilly autumn nights along the River Walk (from Thanksgiving through New Years, the Walk is illuminated with tens of thousands of twinkling lights). The first two weekends in October is when the city celebrates its German heritage with Oktoberfest. In recent years microbreweries such as Freetail and Ranger Creek have raised the local zymurgy profile. Alternately, the historic Pearl Brewery has been renovated into a mixed-use commercial complex with restaurants and locally themed shops, as well as a branch of the Culinary Institute of America.
The crowds thin considerably during the doldrums of winter (January and February), and again when the summer sun bakes the streets (July and August). One place to escape the heat is at the acclaimed Museo Alameda, a Latin arts and culture center affiliated with the Smithsonian.
