Astronomical vs. Meteorological Summer

Depending on whether you measure by astronomy or climate patterns, summer starts on two different days:

Astronomical SummerJune 20–22

Begins at the Summer Solstice, when Earth's axial tilt is at its maximum incline toward the sun in the Northern Hemisphere, providing the year's peak daylight duration.

Meteorological SummerJune 1 – August 31

Spans the three warmest full calendar months (June, July, August) for consistent seasonal weather tracking and climatological comparisons.
