Weather Tidbits: The Vernal Equinox

This edition of Weather Tidbits will be discussing the Vernal Equinox. Also known as the first day of Spring. The Vernal Equinox occurs when the sun shines directly over the equator. This occurred on March 20 at 5:01 AM this year in 2025. Though the date can vary between March 19 to March 21. On the Vernal Equinox, all latitudes on Earth receive roughly 12 hours of daylight and 12 hours of nighttime darkness. The Vernal Equinox shares the same distribution of daylight as the Autumnal Equinox. This is because the sun also shines directly over the equator on the Autumnal Equinox. Based on the Earth’s tilt during its revolution around the sun. The sun’s direct rays shine further up the Northern Hemisphere up to the summer solstice, which is the longest day of the year.
