Look closer. Spring begins the moment the angle of sunlight shifts — not in your thermometer, but in your bones. It begins when you hear the first bird singing before dawn, when the air smells of wet earth and possibility, when the silence of winter cracks open into a chorus. No government or almanac decides this. Your body knows.
The question "What months are spring?" appears simple, yet the answer depends entirely on one's frame of reference. To a meteorologist, spring is a strictly defined three-month block of statistics. To an astronomer, it is a precise moment in the Earth's orbit. To a biologist, it is a fluid, chaotic awakening that varies by latitude and species. This report delineates these differing definitions to provide a comprehensive answer.
If you live in Australia, New Zealand, South America, or southern Africa, spring occurs during the latter half of the calendar year. September, October, November Astronomical period: Late September to late December Month-by-Month Breakdown (Northern Hemisphere)
In the , the seasons are reversed. Meteorological spring occurs during:
April is widely characterized by shifting weather patterns, often summarized by the phrase "April showers bring May flowers."
The months of spring in the Southern Hemisphere are:
The return of songbirds marks a definitive shift in the season.
The most accurate general answer for the Northern Hemisphere is , representing the core months of transition from the dormancy of winter to the heat of summer.
From an astronomical standpoint, spring in the Northern Hemisphere officially begins on the , which typically falls on March 20th or March 21st. This marks the moment when day and night are approximately equal in length, and the sun crosses the celestial equator from south to north. The vernal equinox signals the start of spring, which then spans approximately 92.5 days.
