When to go to Houston; the weather
-
Houston has a semi-tropical climate. The weather is extremely pleasant throughout the year, except in the summer when it is very hot and humid. When it rains, it is generally very heavy, sudden and violent storms, and floods are common. Finally, like all the Gulf of Mexico coast, Houston can get hit by hurricanes from July to October (see my Warning or Danger tips for details on hurricanes).
December-January-February
Temperatures: 40-65ºF (4-18ºC)
Rain: 3' (88 mm)
Wind: from the North
Winter is very mild in Houston. I generally still have beautiful tropical flowers in my garden in December! We generally get only a few nights of freeze. Temperatures vary wildly, sometimes with gorgeous warm days, and others gray and cold. Although the cloudiest months of the year on average, there are still lots of sunny days.
March-April
Temperatures: 50-78ºF (10-26ºC)
Rain: 3' (88 mm)
Wind: from the Southeast
The best time to come to Houston! The weather is generally gorgeous, warm with cool nights. Houston is full of blooming azealeas late in March, and the spectacular wild flower season is at its peak in mid-April. Best time to go see alligators as well.
May-June
Temperatures: 64-90ºF (18-32ºC)
Rain: 5' (130 mm)
Wind: from the Southeast
Extremely pleasant time to be in Houston but only up to mid-June when it generally starts to be too hot and humid. It can rain a lot, like a whole week non-stop (the dramatic flooding from tropical storm Allison happened in June 2001), but you can get plenty of sun (May 2003 was completely dry!).

July-August
Temperatures: 72-93ºF (22-34ºC)
Rain: 4' (90 mm)
Wind: from the South-Southeast
Houston summer is very very very hot and humid. With the humidity, a temperature of 95 can easily feel like more than 100ºF. The nights are also hot and muggy. If you are outside, make sure you have lot of water to drink with you and lots of sun cream. Take a sweater for inside the buildings which are in contrast freezing cold! Although in general sunny, you get occasional violent thunderstorms. It is the peak of the hurricane season, so be aware of the meteo. Thunderstorms and hurricanes can be accompanied by tornadoes, so listen to the radio for warnings during these times. Houston gardens, streets and roads are lined with beautiful colored blooming oleanders, crepe myrtles and hibiscus.
September-October-November
Temperatures: 55-88ºF (10-31ºC)
Rain: 4' (110 mm)
Wind: from the E-NE, then SE, then N
Again a beautiful season, fall in Houston! Pleasant temperatures, lots of sun. Note that it can still be too hot and humid till mid-September and that hurricane season is still on till mid-November. It can rain a lot, like October 2002 where we have not seen the sun for a month! Not too many trees turn into beautiful fall colors like in Canada or New-England. Here it is more subdued as most native species do not loose their leaves: pines are evergreen (duh...) and live oaks loose and gain their new leaves at the same time in March-April only. For fall tree color, it is best to go to some parts of the Hill Country (NW San Antonio, about a 4 hour drive from Houston) as native trees there put on a spectacular show. Hibiscus are still giving spectacular shows, however.
