Whether you live by meteorological or astronomical seasons, it’s no longer a debate: Spring has arrived in Texas.
Here’s what to know about the seasonal shifts in 2026.
It depends on who you ask. While meteorologists will tell you spring begins on March 1 each year, this year’s astronomical spring just kicked off on Friday, March 20.
Meteorologists measure seasons based on the annual temperature cycle. Astronomers, on the other hand, measure seasons by Earth’s position in relation to the sun. The astronomical first day of spring varies by year between March 19 and March 21.
Meteorologists and astronomers do agree on a couple of things: There are four seasons, and each season lasts roughly three months.
When is the spring equinox 2026?
For those living by astronomical seasons, the spring equinox and the first day of spring are one and the same.
The spring equinox marks the first day of spring in the Northern Hemisphere, according to the Old Farmer’s Almanac. It occurs when the sun is directly above the equator, resulting in nearly equal daylight and night hours.

When is the longest day of the year in 2026? When is the shortest?

The longest day of 2026, also known as the summer solstice, is Sunday, June 21. Central Texas will get around 14 hours of daylight.
On the flip side, 2026's winter solstice — the shortest day of the year — is Monday, Dec. 21. Austin will see just over 10 hours of daylight.
The Earth is tilted approximately 23.5 degrees on its axis, and each solstice is dictated by the amount of solar declination, or “ the latitude of Earth where the sun is directly overhead at noon,” according to National Geographic.
