Honeysuckle sweetens the night
A five-day window of the year, read through nine North American climate regions.
Same week, nine climates
A microseason names a five-day window of the solar year. What that window actually looks like on the ground depends on where you are. Below, the same calendar window read through each of nine North American climate regions.
- NENortheast Continental
Honeysuckle sweetens the night
Japanese honeysuckle perfumes parks after dark.
- SESoutheast Subtropical
Heat settles and the rain begins
Summer heat locks in; afternoon thunderstorms arrive with humid intensity, feeding kudzu and swamp vegetation.

- MWMountain West
Thunderheads build by noon
Afternoon monsoon patterns establish; thunderstorms reliably build over peaks, bringing lightning and cool downdrafts.

Lesser ripening, greater heat
Rapid plant growth as heat intensifies; corn silks emerge, wheat berries fill in the harvest belt, insects reach peak activity.
- SWSouthwest Desert

About the 72-microseason calendar
A microseason is a five-day window of the solar year — long enough to notice something change, short enough that the change is specific. The year holds seventy-two of them, six per month, ordered by what the natural world is doing rather than what the clock says. Almanac calendars like this are an old American habit, kept by farmers, gardeners, and birders for centuries; Weather Story collects them into a single reference.
Each microseason is read through nine North American climate regions. The phenological events that mark a five-day window vary with ecology — the strawberries that open in the Northeast might coincide with the first magnolias dropping in the Southeast and the salmonberry blossoms unfurling in the Pacific Northwest. Same week, nine ecologies, nine readings.
