New York and the Chinese solar calendar

In New York, the first freeze typically comes November 18, 26 days after the calendar's Frost's Descent begins on October 23. The last freeze is typically over by April 1, and New York gets 230 days a year without one. Where the calendar and your weather disagree, go by your weather.

Right now

Rain and heat across the whole year

Here rainy days are spread through the year instead of bunching up in the hot months as they do where the calendar comes from, so the calendar's muggy season has no clear match in New York. On a scale from −1 (opposite) to 1 (perfectly together), New York scores -0.27 and the calendar's home region 0.88.

Where the calendar is most wrong about New York

These four two-week stretches are where the calendar's names or advice sit furthest from New York's thirty-year record.

Major Cold 大寒from 2026-01-20

The old calendar's three signs for these weeks, one per five days: 鸡乳 · 征鸟厉疾 · 水泽腹坚

The Su Wen, part of the Yellow Emperor's Inner Classic, calls winter the season of closing and storing (閉藏). Go to bed early and get up late, once the sun is up; stay warm without sweating. That keeps you in step with winter. Go against it, the text warns, and the kidneys suffer, showing up in spring as weakness and collapse (痿厥).

Days with measurable rain34.3%
Days at or below freezing9.8
Daylight9h 40m (+19 min from two weeks ago)
  • Where the calendar comes from, these weeks average about 34.0°F. At Central Park, NY: 33.4°F, 0.6°F cooler.
  • 'Major Cold' names what people in the Yellow River valley saw in nature, not a temperature. At Central Park, NY, the last freeze of spring typically doesn't clear until April 1, still 71 days away; these weeks usually bring about 9.8 freezing days.

Yang deficiency (running low on the body's warmth) traditionally finds winter hard. Here the average low this stretch is 27.3°F.

Minor Cold 小寒from 2026-01-05

The old calendar's three signs for these weeks, one per five days: 雁北乡 · 鹊始巢 · 雉雊

The winter advice above covers these weeks too.

Average, low, high33.7°F / 28.0°F / 39.4°F
Days with measurable rain35.1%
Days at or below freezing9.9
Daylight9h 21m (+7 min from two weeks ago)
  • Where the calendar comes from, these weeks average about 33.1°F. At Central Park, NY: 33.7°F, 0.6°F warmer.
  • 'Minor Cold' names what people in the Yellow River valley saw in nature, not a temperature. At Central Park, NY, the last freeze of spring typically doesn't clear until April 1, still 86 days away; these weeks usually bring about 9.9 freezing days.

Blood stasis (blood that doesn't move freely) traditionally finds cold hard. Here the average low this stretch is 28.0°F.

Pure Brightness 清明from 2026-04-05

The old calendar's three signs for these weeks, one per five days: 桐始华 · 田鼠化为鴽 · 虹始见

The Su Wen calls spring the season when what was stored comes out (發陳). Go to bed later and get up early, it says, and take unhurried walks outdoors. That keeps you in step with spring. Go against it, the text warns, and the liver suffers, showing up in summer as illness from cold.

Average, low, high52.4°F / 44.3°F / 60.5°F
Days with measurable rain38.2%
Days at or below freezing0.5
Daylight12h 47m (+44 min from two weeks ago)
  • Where the calendar comes from, these weeks average about 58.8°F. At Central Park, NY: 52.4°F, 6.4°F cooler.
  • The fastest-warming stretch of the year: 5.9°F warmer than the two weeks before.

Qi stagnation (energy that gets stuck, often felt as low spirits) traditionally finds gray, rainy stretches hard. Rain falls on 38.2% of days in this stretch, against 34.3% across New York's year.

Major Snow 大雪from 2026-12-07

The old calendar's three signs for these weeks, one per five days: 鹖鴠不鸣 · 虎始交 · 荔挺出

The winter advice above covers these weeks too.

  • 'Major Snow' names what people in the Yellow River valley saw in nature, not a temperature. At Central Park, NY, half of all years have had their first freeze by November 18, 19 days before these weeks begin; they usually bring about 6.7 freezing days.

‘vs. calendar’ is how much warmer (+) or cooler (−) each stretch runs here than where the calendar comes from. Rain figures count rainy days, not inches.

The body-type notes follow traditional Chinese medicine as set out in a national standard in China. Tying them to this city's weather is a traditional association, not a finding from modern research. Which type goes with which stretch is our own arrangement: each is matched to the time of year the standard says it finds hard, or, for rain, to the rainiest of the four when it's wetter than New York's year as a whole. Weather doesn't decide anyone's body type. To find yours, take the assessment.

How New York compares with the other thirteen

New York has 230 frost-free days a year, more than 4 of the other cities here. That's 79 more than Denver, which has the fewest. It's 135 fewer than San Francisco, which has the most.

Rain falls on 34.3% of days here over a year. Phoenix is the driest of the fourteen at 9.2% and Seattle the wettest at 43.1%, which puts New York in the middle.

The hottest two weeks here are Minor Heat, with an average high of 85.1°F and rain on 34.1% of days: never especially hot. 7 of the fourteen get hotter at their peak, Phoenix among them.

Where this comes from

The thirty-year averages are NOAA's official 1991–2020 figures, one station per city, read straight from NOAA's records by our own program. Freezing days for each two-week stretch are estimated from NOAA's monthly counts. Figures for where the calendar comes from are based on weather-station measurements and reanalysis data from the Yellow River valley in northern China, where the calendar's names come from. The seasonal advice comes from the Su Wen, in our own translation.
