Last Day Of Summer: When Does Summer End?

As the days grow shorter and a crispness fills the air, many find themselves wondering, "Is today the last day of summer?" The answer depends on whether you're asking astronomically or meteorologically.

Astronomical vs. Meteorological Summer

• Astronomical Summer: Defined by the Earth's tilt and orbit around the sun, astronomical summer ends with the autumnal equinox. This year, that falls on September 22nd or 23rd, marking the point when day and night are approximately equal.
• Meteorological Summer: For meteorological purposes, summer is defined as the months of June, July, and August. This makes it easier for record-keeping and comparing seasonal data. Therefore, the last day of meteorological summer is August 31st.

Why the Difference?

The difference stems from the needs of different fields. Astronomers use precise celestial events, while meteorologists prefer whole months to align with temperature patterns.

What to Expect as Summer Ends

Regardless of which definition you follow, the end of summer brings noticeable changes:

• Cooler Temperatures: Evenings become cooler, and the heat of midday less intense.
• Changing Foliage: Leaves begin their transformation, displaying vibrant reds, oranges, and yellows.
• Shorter Days: Daylight hours decrease, leading to earlier sunsets.

Making the Most of the Remaining Days

Whether you consider it August 31st or late September, there's still time to enjoy the quintessential summer activities. Head to the beach, enjoy a barbecue, or simply relax outdoors and soak up the warmth while it lasts.

So, is today the last day of summer? If you follow meteorological convention, then yes. But astronomically, you still have a few weeks left to savor the season. Enjoy these final days!
