Waxing Crescent · solunar good
Bright and still pushes fish deep, into shade and under structure. Work the edges of the day.
In the water now · September
The sport fish active near Laramie, Wyoming in September — where they hold, how to know one on the line, and the tactic that usually works. Check your licence and the current limits before you go.

Overhead · Laramie, Wyoming
The two clocks nothing on the ground can argue with: the length of the day, and the phase of the moon.
The sun
12h 29m of light

Solar noon

Sunset

A month from now the day will be 1h 21m shorter. Enough light for steady growth.
Right now · Laramie, Wyoming
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.
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.
29 km/h now · 39 peak
Strong enough to shred leaves, dry beds out fast, and make a small boat a poor idea. Stake anything tall.
It pollinates corn and grasses, dries soil, breaks stems — and it decides where the bait, and therefore the fish, end up.

Salmo trutta
Butter-brown flanks with black and red spots ringed in pale halos; few or no spots on the tail.

Oncorhynchus kisutch
White gums, spots only on the upper tail lobe, and a bright silver body turning deep red in the river.

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 14 days to the average first frost (Sep 28).
Next moons
16.9 mm / 7 days
16.9 mm across 3 days — 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.
18.5 °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 29m
Losing about 3 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.
14 days
Average first fall frost is around Sep 28. Nothing you sow now will finish unless it beats that.
The hard edge of the growing season. Ice inside a leaf ruptures its cells — one night ends a tomato and sweetens a parsnip.
