HOUSTON – Astronomical Spring is officially here, Houston!

As Earth shifted on its axis, the suns' rays hit the equator at exactly 4:01 AM, marking the start of spring.

What does this mean for Houston?

  • Earth’s tilt at 23.5° is what gives us seasons. As we enter Spring here in the Northern Hemisphere, the Southern Hemisphere has now started their fall season.
  • During the next three months, we’ll gain daylight every single day until we hit the Summer Solstice on Friday, June 20th at 9:42 PM.
  • The weather also tends to be more active and dynamic in the Spring.
  • We start to get warmer as we have more time for daylight.

So, how much warmer are we going to get?

Our average high temperature for March 20th is 75°. By the afternoon hours on March 20th, 2025, we’re only seeing temperatures in the mid 60s. We’re roughly 15° below normal for the first day of Spring.

Normal spring-time temperatures for us should only increase by about 1° approximately every 5 days and be about 22° warmer by the time we get to the Summer Solstice.

According to the Climate Prediction Center - a subset of the National Oceanic and Atmospheric Administration, or NOAA, over the next 3 months we have a 50-60% chance of having above average temperatures.

This is also dependent on how much rainfall we get, as drier soils allow for the air to heat up faster.

Unfortunately, the next three months don’t look too promising for our precipitation outlook, especially for our friends up to the north and northwest.

We can already see this reflected in our extended forecast!

Temperatures remain above average for a majority of the next 10 days, and only 3 out of the next 10 days have fairly lower chances of rain.

Spring also brings with it a rise in allergy problems.

This is due to plant life starting to bloom and releasing pollen with the warmer temperatures and typically wetter conditions. We have seen over the last couple of months, more rainfall and above average temperatures than we normally do for the winter months.

Those with allergy issues or increased sensitivity to seasonal allergens, may want to take extra precautions before stepping outside.
