Writing your field guide — reading the forecast, the moon and the map…
Overhead · Atlanta, Georgia
The two clocks nothing on the ground can argue with: the length of the day, and the phase of the moon.
The sun
12h 24m of light
Sunrise

Solar noon
13:32
Sunset
19:44
A month from now the day will be 1h 02m shorter. Enough light for steady growth.
Right now · Atlanta, Georgia
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.
26.0 °C soil · 2.2 mm
Warm but dry. Decomposition stalls without moisture — water the compost heap like a plant, and don't expect mushrooms.
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.
2.2 mm / 7 days
Only 2.2 mm over seven days. A garden wants roughly 25 mm a week — water deeply twice rather than lightly every day.
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 60 days to the average first frost (Nov 13).
Next moons
236 frost-free days
Typically Mar 22 to Nov 13 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.
26.0 °C
Warm enough for beans, corn, squash, cucumber and transplanted tomato and pepper. Roots run hard at this temperature.
Seeds read soil temperature, not the calendar. Six centimetres down is where the decision gets made.
12h 24m
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.
