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 Whitehorse, Yukon 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.

Sander vitreus
Olive-gold flanks, a spiny first dorsal, and the big glassy eye that gives it the name and lets it hunt in low light.
Where and how to catch it →
Esox lucius
Long torpedo body, duck-like jaws, light bean-shaped spots on a dark green flank.

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

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.
7 km/h now · 18 peak
Calm. Good for spraying, for transplanting, and for spotting a rise on flat water — but calm bright days push fish deep.
It pollinates corn and grasses, dries soil, breaks stems — and it decides where the bait, and therefore the fish, end up.

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 9 days to the average first frost (Sep 23).
Next moons
3.9 mm / 7 days
Only 3.9 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.
8.6 °C
Cool-season seed only — peas, spinach, radish, fava, and the first lettuce. Beans and corn will sulk.
Seeds read soil temperature, not the calendar. Six centimetres down is where the decision gets made.
12h 55m
Losing about 6 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.
9 days
Average first fall frost is around Sep 23. 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.
