The differences between meteorological and astronomical summer are as follows. Meteorological summer is based on the calendar and temperature cycles, spanning from June 1 to August 31. This method aids in consistent climate data collection and weather forecasting. In contrast, astronomical summer is determined by Earth’s tilt and orbit, starting with the summer solstice around June 20-21 and ending with the autumn equinox around September 22-23. Understanding both definitions helps explain variations in seasonal weather patterns and data reporting. https://www.accuweather.com/en/space-news/meteorological-summer-vs-astronomical-summer-explained/1780019
