Warm water holds less oxygen. Fish the springs, the inflows and the deep water, and release quickly.
In the water now · September
The sport fish active near Phoenix, Arizona 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 · Phoenix, Arizona
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 01m shorter. Enough light for steady growth.
Right now · Phoenix, Arizona
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.
6 km/h now · 31 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 103 days to the average first frost (Dec 26).
Next moons
126.1 mm / 7 days
126.1 mm in a week is a lot. Expect blight pressure on tomatoes and potatoes, slugs at night, and blown-out, muddy rivers.
Sets the pace for everything: germination, fungal fruiting, slug nights, and how a river runs for the next three days.
36.7 °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 23m
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.
328 frost-free days
Typically Feb 1 to Dec 26 here. Coldest night in the next week: 23.4 °C.
The hard edge of the growing season. Ice inside a leaf ruptures its cells — one night ends a tomato and sweetens a parsnip.
