San Antonio, TX has weather not unlike other locales from the southernmost states in the country. The summers are very hot, and the winters are incredibly mild in comparison to what goes on up north. Here’s a basic breakdown of some of what you can expect throughout the year:
1 – The Temperature
Late May through mid September include the hottest temperatures, with an overall average of around 90 degrees Fahrenheit. The temperatures soar to their highest in August. As for the winter, the cold lasts for a much shorter duration: the end of November through the end of February. The daily highs average around 70, with lows in the 40s. The coldest weather traditionally comes just after the start of January.
2 – The Precipitation
San Antonio, TX has varied amounts of precipitation through the year. Roughly half the year – between April and October to be exact – has a 22 percent chance of rain on any given day. May is traditionally the rainiest month of the year.
The other half of the year is a fair bit drier. There’s usually only around a 13 percent chance of any rain starting from the middle of fall through the beginning of spring. Any forms of precipitation outside of rain are quite rare, though not unheard of.
3 – The Humidity
San Antonio can be quite muggy, especially throughout the middle of the year. It only serves to make the heat seem that much more oppressive. The effect isn’t quite as dire as in some of the states to the east, but it can be rather uncomfortable for anyone wearing too many layers of clothing. The relatively low humidity through the fall and winter help keep the temperatures rather warm however, which is a big plus for anyone that hates colder weather.
4 – The Wind
Again, the year is split essentially in two when it comes to windy weather. January through July contains average wind speeds of around 5 miles per hour in San Antonio. The peak is usually near the beginning of April, where the average can climb close to 6 mph. The rest of the year is notably calmer however, especially in September. The wind traditionally comes from the south for most of the year: around 10 months or so, to be exact. Again, this serves to add to the overall warm nature of the city’s weather.
