In the winter, you can expect average highs in the low 60s with the rare, freak snowfall thrown into the mix. Come summertime, it's imperative to crank up the air conditioning. Average highs in May begin climbing into the mid 80s and reach 90 degrees Fahrenheit by June, with the hottest months being July and August as averages hover in the low 90s. However, you might feel hotter outside than the thermometer reads due to the heat index.
June is Houston's wettest month, with an average rainfall of more than 7 inches. After June's heavy rainfall comes mosquito season, with more than 55 species of the biting bugs invading the area. When the humidity bumps the heat index to 108 degrees F or more for two consecutive days, the city activates its heat emergency plan. Heat shelters at recreation centers and libraries open their doors to give everyone an air conditioned break. Call 311 for heat shelter locations and to arrange transportation.
The Gulf Coast braces for hurricanes from June 1 through November 30. Many Houstonians, familiar with the damage that these storms can cause, dutifully secure their homes and review evacuation plans when a hurricane looms. Much of the Texas coastline is less than 10 feet above sea level, and high winds and tides can create surges of 20 feet or more. Storm surges damage property and flood low-lying areas. When visiting Texas, you can keep up with the latest hurricane and evacuation information on the governor's website.
Stifling heat and humidity doesn't mean you need to call off your Houston travel plans. Keep well hydrated and stay indoors or plunge into the hotel pool during a heat emergency. Dress for the heat with light-colored, breathable, loose-fitting clothing and wear a wide-brimmed hat to protect yourself from the sun. Use mosquito repellent and avoid perfumes that attract insects, especially if you participate in outdoor activities in the early morning and evening. Pay special attention to the hydration and cooling needs of children, the elderly and those with medical conditions in your party.
