Fall (September to December) and winter (December to March) are the best times to visit San Antonio. The weather is usually mild, with temperatures between 64 and 85 degrees Fahrenheit and three or four days of rain per month.

Around the last week of September, hotels and airlines will lower their rates because they want to attract out-of-season visitors. However, costs around holidays like Thanksgiving and Christmas will be expensive, and accommodation and flights can book up quickly.

However, if you can't visit in January, you can find affordable tickets in February and the first half of March. You'll also notice the cost of flying starts to drop at the beginning of October.

Since fewer people can travel in the fall (September to December) and winter (December to March), airlines are more inclined to offer deals. However, December will have surge pricing, which increases costs around Christmas.

When is the worst time to visit San Antonio?

Locals will tell you that summer (June to September) is the worst time to visit San Antonio. It's the hottest season when temperatures rarely fall below 90 degrees Fahrenheit; this makes it uncomfortably hot when exploring the city.

Not only is it hot, but it's also crowded. By the first week of June, most schools around the country will have ended their year, so more families will be traveling to popular destinations like San Antonio.

More tourists mean a high demand for hotel accommodation and flight tickets. This fact means prices increase for both, and accommodation may be difficult to find. Book early to ensure you get accommodation and flights at the best rates.

January in San Antonio

January is one of the best times to visit San Antonio. Its climate is mild, and temperatures average around 64 degrees Fahrenheit. It typically rains about once a week.

The crowd levels are low because fewer people travel in January compared to the rest of the year. You won't encounter many other tourists, resulting in shorter wait times for activities and restaurants.

To encourage out-of-towners to visit the city, flights and hotels will offer their lowest prices throughout the month, thus making your trip more budget-friendly.

February in San Antonio

There are many things to do on a date in San Antonio, making it the ideal place to visit in February for a Valentine's Day getaway.

In addition, San Antonio's February weather is comfortable. The temperature is around 67 degrees Fahrenheit in the daytime and 43 degrees Fahrenheit at night.

Valentine's Day weekend can get a little crowded, but, in general, February is a low season for tourism. So you won't often run into large groups of tourists, and lines should be relatively short.

Hotels, flights, and other amenities should suit your budget. If you like to plan spontaneous trips, you'll be more likely to find last-minute options in February.

March in San Antonio

March is on the cusp between winter (December-March) and spring (March-June), so you'll be able to see the seasons change in San Antonio. The most significant change you'll notice is the weather.

The average temperature is around 74 degrees Fahrenheit; however, the first half of the month is colder, with daily averages of around 67 degrees Fahrenheit. On the other hand, the second half of the month sees temperatures reaching as high as 80 degrees Fahrenheit.

Crowd levels are typically manageable. However, be prepared for an influx of tourists around halfway through the month as schools start letting out for spring break.

Hotel prices and flights are relatively budget-friendly in March. Booking a month or two in advance will probably guarantee reservations at affordable prices.

April in San Antonio

April in San Antonio has close to perfect weather. The climate is warm and stable at around 80 degrees Fahrenheit, with only three days of rain on average.

If you plan to take a tour of San Antonio, April is the best time to do so. Crowd levels start to increase, but they won't be overwhelming, and a tour will help you navigate the city even on busy days.

You can visit the area on a budget in April, but you might need to do a little extra planning first. Booking early allows you to find the best deals on flights, hotel rooms, and attraction tickets.

May in San Antonio

Depending on your travel preferences, May is a hit-or-miss month to visit San Antonio. The weather is beautiful, the sky is clear most days, and 86 degrees Fahrenheit is the average high.

However, May is also a busy month in the city. The weekends of Mother's Day and Memorial Day are two of the busiest. There will be no avoiding the crowds of residents and tourists all over the city.

If you're a budget traveler that wants to visit in May, book your San Antonio travel plans at least a month in advance. Places to lay your head are quickly filled, making last-minute deals unlikely.

June in San Antonio

If you want to visit San Antonio in the summer (June to September), June is the best time to plan your trip. However, be warned that daily temperatures are typically around 93 degrees Fahrenheit.

It's a little cooler at night, averaging 72 degrees Fahrenheit, making it bearable to experience San Antonio's nightlife.

June marks the start of the summer (June to September) vacation, so you'll notice a lot of families and university students in the city. Be prepared to pay premium prices for accommodation and traveling, especially if you wait until the last minute to finalize your plans.

July in San Antonio

San Antonio is beautiful in July. The city goes all out and decorates in red, white, and blue for Independence Day, and the sky is clear most days. However, it's hot, crowded, and expensive.

The average daily temperature in July is 94 degrees Fahrenheit. If you plan to walk around the city, wear sun protection and stay hydrated.

People will take advantage of the summer (June to September) holidays and choose to travel, so be prepared for crowds. To avoid intensely high crowd levels, try to book activities that take you out of the city center, like a tour of the Cave Without A Name.

A flexible budget is ideal if you travel in July, and booking your hotel and flight two months in advance will save you even more. Leaving it till the last minute will make it nearly impossible to find discounts.

August in San Antonio

August is the hottest month in San Antonio. Temperatures regularly range between 95 and 100 degrees Fahrenheit, and it rains less than once a week.

Temperatures can feel even hotter if you run into crowds, which is a given if you visit during this month. Thousands of tourists come for their end-of-summer family vacations before the school year starts again.

Traveling in the first half of August tends to be more expensive than in the second half because schools will begin classes again midway through the month, causing the demand for flights and accommodation to drop.

September in San Antonio

September is one of the best months to visit San Antonio, and after Labor Day weekend, crowd levels drop.

You won't have to deal with overwhelming crowds at the city's most famous landmarks. If you book a tour of San Antonio's missions, you'll be able to take in the sights without navigating around large groups.

September's weather changes as the month progresses. The first half of the month is usually warmer at around 90 degrees Fahrenheit. However, as summer (June to September) turns into fall (September to December), the daily average tends to be closer to 80 degrees Fahrenheit.

Prices for lodging and flights fall steadily throughout September, and you'll most likely find discounts if you book a month ahead.

October in San Antonio

There are many reasons to visit San Antonio in October. The climate is pleasant, with temperatures around 81 degrees Fahrenheit during the day and 59 degrees Fahrenheit at night.

There are Halloween events around the city catering to people of all ages. For example, you can take a San Antonio ghost tour if you're interested in some of the city's spookier history.

Crowds are manageable in October as school is in session and families and students are not inclined to travel. Fewer tourists mean less demand for amenities, so you can usually find deals on accommodation, plane tickets, and some activity admissions.

November in San Antonio

If you're trying to decide when to visit San Antonio, consider booking a trip in November. This month marks the official beginning of the city's "low season" for tourism, so you can enjoy the city without worrying about the overwhelming crowds of the summer months.

Prices will lower throughout the month, with many hotels and airlines offering deals to entice out-of-season travelers. The one exception to that rule is Thanksgiving weekend which will probably see an influx of tourists. Again, booking a month or more in advance will mean you'll still be able to have a budget-friendly trip.

San Antonio's weather in November is mild. Temperatures are steady at 72 degrees Fahrenheit during the day and 49 degrees Fahrenheit at night.

December in San Antonio

December can be one of the best times to plan a trip to the San Antonio area. It rarely gets cold enough to snow, so you can walk around the city in mild 64 degrees Fahrenheit weather. A San Antonio New Year's Eve should also not be missed!

Do note that Christmas in San Antonio can be crowded. As schools let out for winter (December to March) break around the end of the month, more families can travel. Until then, though, the city usually isn't too busy with tourists.

Flights to San Antonio are quite expensive in December as the airlines know people will travel for the holidays, so they're less likely to offer discounts. Keep that in mind and book in advance. However, hotels usually have lower rates until the middle of the month.

In Summary

Whether you're a history buff or are interested in art and culture, San Antonio has something for everyone to see and enjoy, no matter when you visit. However, your preferences can affect when you should visit the "Alamo City."

The weather is beautiful all year. However, summer (June to September) temperatures routinely top 90 degrees Fahrenheit, while winter (December to March) is a mild 64 degrees Fahrenheit on average.

Extroverts will love how busy the city gets in the summer, and people with low crowd tolerances will prefer how quiet winter is. This low season also tends to be cheaper if you want to travel on a budget.

Hopefully, this list has helped you determine your preferences so you can have the best San Antonio trip possible. Now all you have to do is plan it!
