However, these dates do not necessarily correspond to the actual weather patterns experienced in different regions. For example, in the Northern Hemisphere, the warmest months are usually July and August, while the coldest months are January and February. This discrepancy led meteorologists to develop an alternative way of defining seasons, based on annual temperature patterns.

Consider the difference in defining "Summer" between the two systems: meteorological seasons

Meteorological seasons are a method of dividing the year into four distinct periods—Winter, Spring, Summer, and Autumn—based on the annual temperature cycle and the calendar month. Unlike astronomical seasons, which are defined by the Earth’s axial tilt and solstices/equinoxes, meteorological seasons are fixed to specific dates for consistency in climate analysis, weather forecasting, and statistical record-keeping. This report outlines the definition, timing, scientific rationale, advantages, and limitations of meteorological seasons. However, these dates do not necessarily correspond to
