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 Philadelphia, Pennsylvania 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.

Micropterus dolomieu
Bronze-brown with vertical bars, red eye, and a jaw that ends level with the eye — not past it.

Overhead · Philadelphia, Pennsylvania
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 18m shorter. Enough light for steady growth.
Right now · Philadelphia, Pennsylvania
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 · 20 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 57 days to the average first frost (Nov 10).
Next moons
0.6 mm / 7 days
Only 0.6 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.
24.0 °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 28m
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.
209 frost-free days
Typically Apr 15 to Nov 10 here. Coldest night in the next week: 12.6 °C.
The hard edge of the growing season. Ice inside a leaf ruptures its cells — one night ends a tomato and sweetens a parsnip.
