Miami and the Chinese solar calendar

The Chinese calendar has a fortnight called Frost’s Descent. In Miami, the thirty-year record contains no freeze at all — not in that fortnight, not in any other. Rain and heat do move together here (r = 0.91), much as they do in the calendar’s home climate (r = 0.88) — on this one axis the seasonal picture carries over.

Rainy days and heat move together where you are (r = 0.91), as they do in the prototype (r = 0.88) — on this one axis the classical seasonal picture transfers.

Where the calendar is most wrong about Miami

Of the twenty-four fortnights, these four are the ones whose name or advice sits furthest from what Miami’s weather station actually recorded over thirty years.

Major Snow 大雪from 2026-12-07

Pentads: 鹖鴠不鸣 · 虎始交 · 荔挺出

closing and storing (閉藏 bì cáng). Go to bed early and rise late — wait for the sunlight. Leave the cold, stay near warmth, and do not let the skin sweat open.

This is the response to winter qi — the way of nourishing the storing (養藏). Going against it is said to injure the kidney, so that spring brings weakness and collapse and there is less to carry the bringing-forth.

Average / low / high71.6°F / 64.7°F / 78.4°F

Daylight10h 35m (-10 min from two weeks ago)
  • This fortnight's advice was written for a place averaging 36.3°F at this point in the year. At Miami Intl, FL the 1991–2020 average is 71.6°F — warmer by 35.3°F.
  • The name of this fortnight, 'Major Snow', is a phenological marker from the Yellow River valley — an observation of what was seen happening, not a temperature threshold. At Miami Intl, FL a normal year records 0.0 days at or below freezing in total. The name and the thermometer are two different kinds of statement, and here they part company entirely.

If Yang deficiency came out high for you. Traditional theory associates Yang deficiency with feeling the cold sooner than the people around you. That is a theoretical association drawn from the classical literature, not a research finding. Your average low this fortnight is 64.7°F, and about 0.0 days typically fall to freezing or below. Whether any of it matters for you is something to observe, not something this page can tell you.

Minor Cold 小寒from 2026-01-05

Pentads: 雁北乡 · 鹊始巢 · 雉雊

Same seasonal passage as above — the classical text gives one instruction per season, not one per fortnight.

Average / low / high68.4°F / 60.8°F / 76.0°F
Days with measurable rain24.4%
Days at or below freezing0.0
Daylight10h 35m (+4 min from two weeks ago)
  • This fortnight's advice was written for a place averaging 33.1°F at this point in the year. At Miami Intl, FL the 1991–2020 average is 68.4°F — warmer by 35.3°F.
  • The name of this fortnight, 'Minor Cold', is a phenological marker from the Yellow River valley — an observation of what was seen happening, not a temperature threshold. At Miami Intl, FL a normal year records 0.0 days at or below freezing in total. The name and the thermometer are two different kinds of statement, and here they part company entirely.

If Yin deficiency came out high for you. Traditional theory associates Yin deficiency with internal dryness and a sense of heat from within. That is a theoretical association drawn from the classical literature, not a research finding. Your average high this fortnight is 76.0°F, and 24.4% of days typically see measurable rain. Whether any of it matters for you is something to observe, not something this page can tell you.

Major Cold 大寒from 2026-01-20

Pentads: 鸡乳 · 征鸟厉疾 · 水泽腹坚

Same seasonal passage as above — the classical text gives one instruction per season, not one per fortnight.

Average / low / high68.8°F / 61.2°F / 76.5°F
Days with measurable rain22.5%
Days at or below freezing0.0
Daylight10h 45m (+10 min from two weeks ago)
  • This fortnight's advice was written for a place averaging 34.0°F at this point in the year. At Miami Intl, FL the 1991–2020 average is 68.8°F — warmer by 34.8°F.
  • The name of this fortnight, 'Major Cold', is a phenological marker from the Yellow River valley — an observation of what was seen happening, not a temperature threshold. At Miami Intl, FL a normal year records 0.0 days at or below freezing in total. The name and the thermometer are two different kinds of statement, and here they part company entirely.

If Qi stagnation came out high for you. Traditional theory associates Qi stagnation with mood that moves with the season; the classical texts tie autumn's gathering-in to it in particular. That is a theoretical association drawn from the classical literature, not a research finding. Daylight at your latitude is 10h 45m, up 10 minutes from two weeks ago. Whether any of it matters for you is something to observe, not something this page can tell you.

Frost's Descent 霜降from 2026-10-23

Pentads: 豺祭兽 · 草木黄落 · 蛰虫咸俯

containment and levelling (容平 róng píng). Go to bed early and rise early, up with the rooster.

This is the response to autumn qi — the way of nourishing the gathering-in (養收). Going against it is said to injure the lung, so that winter brings undigested diarrhoea and there is less to carry the storing.

Su Wen, 'Four Qi Regulate the Spirit' (素問·四氣調神大論); pentads from the Yue Ling Qi Shi Er Hou Ji Jie

Average / low / high77.5°F / 71.4°F / 83.7°F
Days with measurable rain36.0%
Days at or below freezing0.0
Daylight11h 19m (-22 min from two weeks ago)
  • This fortnight's advice was written for a place averaging 53.4°F at this point in the year. At Miami Intl, FL the 1991–2020 average is 77.5°F — warmer by 24.1°F.
  • The name of this fortnight, 'Frost's Descent', is a phenological marker from the Yellow River valley — an observation of what was seen happening, not a temperature threshold. At Miami Intl, FL a normal year records 0.0 days at or below freezing in total. The name and the thermometer are two different kinds of statement, and here they part company entirely.
  • This is the fastest-cooling fortnight of your year: 2.9°F below the one before it.

If Damp-heat came out high for you. Traditional theory associates Damp-heat with damp and heat arriving together, rather than either one alone. That is a theoretical association drawn from the classical literature, not a research finding. This fortnight runs to an average high of 83.7°F with rain on about 36.0% of days. Whether any of it matters for you is something to observe, not something this page can tell you.

‘vs. calendar’ is this fortnight’s local average minus the average where the calendar was written. Rain figures on this page count rainy days, not inches. The two can point opposite ways — summer storms drop more water on fewer days.
