At The Old Farmer’s Almanac, we’ve been forecasting the weather since the days of George Washington—over 234 years ago—so we know a thing or two about making predictions. In colder regions, winter often means shoveling, snow blowing, dealing with bad roads, and challenging temperatures. Learn more about the Celtic calendar. Meteorological winter starts on December 1 and includes December, January, and February. Thus, meteorologists break the seasons down into groupings of three months. Because of these factors, it’s impossible to point to the same date year after year and call it the coldest day.
Warmer and drier conditions are expected in the High Plains, along with below-normal snowfall. Expect milder months in the Upper Midwest to transition to colder-than-normal temperatures as winter continues. Expect colder temperatures in the Ohio Valley, with a wetter eastern area and a number of snowy periods throughout the season. Winter will be tough in the Appalachians, with colder and snowier conditions, especially in the north. But colder-than-usual temperatures are expected from central New England south through the Appalachians and into the Ohio Valley. In the winter season the sun it not active, as usual, temperatures are low and days are really cold.
In Chinese astronomy and other East Asian calendars, winter is taken to commence on or around 7 November, on Lìdōng, and end with the arrival of spring on 3 or 4 February, on Lìchūn. In Celtic nations, winter began on 1 November and the time around the winter solstice was seen as the middle of winter. Likewise, in Christian Anglo-Saxon calendars, winter began on 7 November, its midpoint was the solstice or Midwinter on 25 December, and winter ended on 6 February. In this region, snow occurs every year in elevated regions such as the Andes, the Great Dividing Range in Australia, the mountains of New Zealand, and in the southerly Patagonia region of South Argentina. The Swedish Meteorological Institute (SMHI) defines thermal winter as when the daily mean temperatures are below 0 °C (32 °F) for five consecutive days.

Season dates for the year 2026

Strong El Niño winters often favor milder temperatures across much of the United States and wetter conditions in parts of the West and South. This year’s El Niño is expected to be strong, with unusually warm waters across the equatorial Pacific. Last winter’s La Niña faded to neutral conditions, and El Niño returned during the summer. A strong El Niño has returned and is expected to continue through winter. Expect a mild winter in the Desert Southwest, with warmer and drier conditions, including in areas that usually receive snow.

Winter Solstice

Everyone feels some magic in the air, because of frosts, crystal nights, snow and just this amazing atmosphere. Hades tricked Persephone into eating the food of the dead, so Zeus decreed that she spend six months with Demeter and six months with Hades. The process by which plants become acclimated to cold weather is called hardening. Few plants bloom in the winter, one exception being the flowering plum, which flowers in time for Chinese New Year. Larger plants, particularly deciduous trees, usually let their upper part go dormant, but their roots are still protected by the snow layer.
The season change dates are based on the spring and fall equinoxes as well as the summer and winter solstices. Each season lasts approximately 3 months and corresponds to a period of the year which has a relative constancy in terms of temperature and climate. The polar vortex isn’t a storm—it’s a large swirling pool of very cold Arctic air that usually stays near the North Pole in winter. If the polar vortex shifts south, it could send colder-than-average air from Canada farther into the United States.

The temperatures are state-wide averages calculated from temperatures recorded during the months of December, January and February. Blizzards occur when strong wind causes blowing snow and whiteout conditions, making roads impassable.

For 235 years, The Old Farmer’s Almanac has mixed practical advice with the unexpected. The Atlantic’s warm pattern is expected to continue, while the Pacific’s cool pattern should weaken.

• The winter solstice is significant across cultures, signaling the changing of the seasons.
• The season change dates are based on the spring and fall equinoxes as well as the summer and winter solstices.
• A snowier-than-normal winter is expected from central New England through the Appalachians, in the Intermountain region and Pacific Northwest, and in Alaska.
• Winter is the best time for plants and trees to relax and prepare for the next season.
• Specifically, it’s the exact moment when a hemisphere is tilted as far away from the Sun as possible.
• For the ancient Celts, the calendar was based around the solstices and equinoxes, marking the Quarter Days, with the midpoints called Cross-Quarter Days.

Equinoxes

In one winwinter casino astronomical reckoning, the winter solstice is the middle of winter; being the day of the year that has fewest hours of daylight. Since by almost all definitions valid for the Northern Hemisphere, winter spans 31 December and 1 January, meaning that the season takes up two calendar years, as summer does in the Southern Hemisphere. In the Northern Hemisphere, depending on the year, this corresponds to the period between 20, 21 or 22 December and 19, 20 or 21 March.
This corresponds to the months of December, January and February in the Northern Hemisphere, and June, July and August in the Southern Hemisphere. In comparison, Vancouver, a city on Canada’s west coast with a marine influence from moderating Pacific winds, has a January low of 1.4 °C (34.5 °F), with days well above freezing, at 6.9 °C (44.4 °F). From the perspective of an observer on the Earth, the winter Sun has a lower maximum altitude in the sky than the summer Sun. Conversely, winter in the Southern Hemisphere occurs when the Northern Hemisphere is tilted more toward the Sun. The day on which this occurs has the shortest day and the longest night, with day length increasing and night length decreasing as the season progresses after the solstice.

• Across much of the country, temperatures are expected to be near normal or warmer than normal.
• The winter solstice marks the official beginning of astronomical winter (as opposed to meteorological winter, which starts about 3 weeks before the solstice).
• For those of us in the Northern Hemisphere, this means that the Sun’s path is as low in the sky as it can get—even at high noon.
• In Chinese astronomy and other East Asian calendars, winter is taken to commence on or around 7 November, on Lìdōng, and end with the arrival of spring on 3 or 4 February, on Lìchūn.
• The moment of winter solstice is when the Sun’s elevation with respect to the North or South Pole is at its most negative value; that is, the Sun is at its farthest below the horizon as measured from the pole.
• Ecological reckoning of winter differs from calendar-based by avoiding the use of fixed dates.
• Because of these factors, it’s impossible to point to the same date year after year and call it the coldest day.

Most of plants and animals are having their hibernation period, so winter is not full of bright colors, but who says that white, snowy and a bit magical winter is not cool? Nature in the winter season is sleeping, because of low temperatures, frost in the air and snowing weather. Ecological reckoning of winter differs from calendar-based by avoiding the use of fixed dates.
Thankfully, after we reach the winter solstice, the days begin to grow longer and longer again until we reach the summer solstice—the first day of summer and the longest day of the year. (The Southern Hemisphere’s winter solstice occurs in June.) For the Northern Hemisphere, the winter solstice occurs every year between December 20 and 23, most often on December 20 or 21. If the astronomical or calendrical seasons begin with the equinoxes (spring and autumn) and solstices (summer and winter), in meteorology, they begin earlier and correspond to periods of three full months.
