eSIM Texas

Texas has four distinct climate zones and the best time to visit depends on your destination. For all four major cities, March through May and October through November are ideal. Spring offers mild temperatures from 18C to 28C, bluebonnet wildflower season along Texas highways in April, and the South by Southwest festival in Austin in March. Fall brings similarly comfortable temperatures, the State Fair of Texas in Dallas (October), and Austin City Limits Music Festival in October. Summers in Texas are genuinely hot: Dallas and San Antonio regularly hit 37C to 40C in July and August. Houston combines heat with extreme humidity. Austin is a slightly cooler option but still very hot in summer. Air conditioning is universal across Texas. Winter is mild in most of the state: temperatures in Dallas and Austin range from 6C to 14C in January. Snowstorms are rare but can be severe when they occur in North Texas. West Texas and Big Bend have the mildest winters and are best visited from October through April. The Texas coast at Galveston and South Padre Island is warm most of the year with hurricane season running from June through November.
