San Antonio, Texas Weather in April

April weather

April is one of the best months to visit San Antonio, and its comfort score of 9.3 out of 10 earns it an Excellent rating. Afternoons usually reach around 29°C, and nights drop to about 15°C, so you can comfortably spend the day outside. Rain falls on about seven days, but most showers pass quickly and leave plenty of time for your plans. November to April is the city's best stretch overall, and April sits at the warm end of it. By May, highs climb to 32°C and rainfall roughly doubles, so this is the month to go before the heat settles in.

That mild weather suits the River Walk, the Alamo, and the shady paths at the Japanese Tea Garden. You can also explore the Mission Reach trail before May's stronger heat arrives. If a wet spell rolls in, slow down and head to indoor stops like the San Antonio Museum of Art.

Fiesta and spring crowds

Fiesta San Antonio often takes place in April, bringing parades, music, and events across the city. The Battle of Flowers Parade is a longtime favourite. Dates change each year, so check whether your trip overlaps with the celebrations. Expect downtown to be busy, and hotel prices nearby may rise during the festivities.

Spring break and Easter can also draw families to the River Walk and the San Antonio Zoo. April is part of the city's popular travel season, so it's usually busier than the quieter summer months. For families, Fiesta's colourful parades are a real highlight, but the crowds along the routes can be large.

Getting around

If you want a calmer walk during Fiesta, head to the Mission Reach section of the River Walk, south of downtown. It links several historic missions and feels more open than the central stretch. The trail is best when it's dry, since rain can leave parts muddy.

If you're visiting the Alamo on a parade day, check street closures before you walk over from your hotel. Fiesta crowds can turn a short downtown trip into a long one. On quieter days, April's mild evenings are perfect for a stroll along the river and dinner nearby.
