The winter of 2026 is shaping up to be notably different for Memphis, as warm weather envelops the city. While the official start date for astronomical spring is March 20, residents are already feeling the effects of an unusually warm January. This early warmth could leave many locals anticipating the arrival of spring as they enjoy temperatures in the upper 60s.
Spring 2026 Start Date: Unseasonably Warm Weather in Memphis
The first day of meteorological spring falls on March 1, while astronomical spring begins on March 20. This year, Memphis will experience near-record temperatures from January 6 to 9, with highs reaching between 67 and 70 degrees. This is well above the seasonal average, which typically hovers around the lower 50s.
Recording High Temperatures
- January 6-9 temperatures: 67-70 degrees
- Seasonal normal temperature: lower 50s
- Record high temperatures for this period: 74-75 degrees
The National Weather Service forecasts that several regions in north Mississippi might tie or break high temperature records during this period. An upper-level ridge over the Yucatan Peninsula is contributing to this warming trend.
Comparing Seasonal Differences
Historically, such warmth in January contrasts sharply with the winter of 2025. At that time, Memphis faced a snowstorm that produced 7.5 inches of snow, shutting the city down for a week. Both winters were influenced by the La Niña climate pattern, but in 2026, a weakening La Niña is resulting in these milder temperatures.
Understanding Astronomical vs. Meteorological Seasons
Astronomical seasons are determined by the Earth’s position relative to the sun, marked by equinoxes and solstices. Conversely, meteorological seasons are based on temperature cycles. Notably, the last March 21 equinox in the mainland United States occurred before 2000, with the next one not expected until 2101.
Key Definitions
- Equinox: Occurs in spring and fall when day and night are approximately equal.
- Solstice: Happens in winter and summer, marking the shortest or longest days.
As Memphis continues to bask in warm temperatures, residents are reminded that true spring weather is still a few weeks away. For now, the city will continue to experience this unusual January warmth, creating a feel of early spring in the air.
