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 0h 45m shorter. Enough light for steady growth.
Right now · Brownsville, Texas
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.
33.5 °C soil · 1.1 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.
1.1 mm / 7 days
Only 1.1 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 108 days to the average first frost (Dec 31).
Next moons
350 frost-free days
Typically Jan 15 to Dec 31 here. Coldest night in the next week: 25.2 °C.
The hard edge of the growing season. Ice inside a leaf ruptures its cells — one night ends a tomato and sweetens a parsnip.
33.5 °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 19m
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.

Your woods
The commonest trees recorded nearby, most often seen first. Most of the good mushrooms are tied to a particular tree, so this is the first thing to know about a wood.
Know these first
2 species on our hazard list have been recorded near here this month. Learn these before you learn anything you intend to eat.
Chlorophyllum molybdites
Toxicodendron radicans
These are recorded within about 40 km of here in this month, from verified public observations. It is not a complete list of what is dangerous — nothing is — and a species missing from it may still be in your woods. Never eat anything identified from a photograph and a description alone.
