Another month has come and gone! As we flip the calendar over to the month of May, here’s a look back at how April’s weather measured up in San Antonio.
Temperatures
- Coolest morning low: 45 degrees on April 3
- Warmest afternoon high: 90 degrees on April 9 and April 29
- Average monthly temperature: 72.5 degrees -- 3.1 degrees above average
While we still needed the light jacket for a few mornings, those are now becoming few and far between as we march through the spring season.
San Antonio also hit 90 degrees twice this month. For comparison, April 2023 also managed to climb into the low 90s twice.
Rainfall
- Monthly rainfall total: 3.07 inches
- Highest daily rainfall total: 1.29 inches on April 9
- Number of days with measurable rainfall: 7
This month rang in wetter than average with a monthly rainfall total of 3.07 inches. This is 0.65 inches above the average of 2.42 inches!
The last time we saw above-average rainfall in a month was January 2024, when 6.72 inches of rain officially fell in the Alamo City.
This brings our year-to-date total to 11.54 inches, which is 3.11 inches above where we should be for this time of year, on average.
Drought Conditions
While a decent amount of rain fell in San Antonio throughout the month of April, the same unfortunately can’t be said for the far western portions of our area.
In fact, Del Rio only officially recorded 0.18 inches of rainfall over the 30-day period, which was 1.32 inches below average.
This caused drought conditions to worsen along and west of the I-35 corridor, which can be seen on the drought monitor comparisons from the beginning of the month to the end.
