The two clocks nothing on the ground can argue with: the length of the day, and the phase of the moon.

A month from now the day will be 1h 06m shorter. Enough light for steady growth.
Right now · Oklahoma City, Oklahoma
Nothing here is a guess. Each of these is read from this week's forecast and this location's climate record, and each one is pushing the season one way or the other.
32.6 °C soil · 5.4 mm
Steady breakdown. Worms and fungi are moving last year's leaves into this year's soil.
Fungi and bacteria turning last season into next season's soil. The same warm, wet window that runs a compost heap also fruits the mushrooms.
5.4 mm / 7 days
5.4 mm across 1 day — short of the ~25 mm a week most beds want. Top up the thirstiest rows.
Sets the pace for everything: germination, fungal fruiting, slug nights, and how a river runs for the next three days.

The moon
Waxing Crescent
11% lit · waxing · day 3 of 29.5
Planting by the moon: New to first quarter: sow leafy crops and anything harvested for its leaves — lettuce, spinach, brassicas, herbs.
Fishing: good — feeding peaks in the days either side of new and full, and around moonrise and moonset.
Turn of the season
Fall equinox
Sep 22 · 7 days away
About 56 days to the average first frost (Nov 9).
Next moons
222 frost-free days
Typically Apr 1 to Nov 9 here. Coldest night in the next week: 21.1 °C.
The hard edge of the growing season. Ice inside a leaf ruptures its cells — one night ends a tomato and sweetens a parsnip.
32.6 °C
Hot soil: germination drops off above 30 °C and roots slow. Mulch, shade the row, and sow late in the day.
Seeds read soil temperature, not the calendar. Six centimetres down is where the decision gets made.
12h 25m
Losing about 2 minutes of daylight a day.
The one thing weather can't change. Plants count photoperiod to decide when to bolt, bulb, flower and go dormant.
Waxing Crescent · 11%
Waxing, 3 days old. Full moon in 11 days. Fishing outlook: good.
It moves water — in the sea, in a lake's edge, and, by long tradition, in the sap of a plant. Fish feed hardest on the days around new and full.
