Behind this week's fishing
The day, the ground and the sky over Oslo
Bright and still pushes fish deep, into shade and under structure. Work the edges of the day.
- Brown troutbest now — The most nocturnal trout there is. After dark the big ones leave cover and hunt the shallows and the tailouts.

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

Sunrise

Solar noon

Sunset

A month from now the day will be 2h 39m shorter. Enough light for steady growth.
The moon

Planting by the moon: Last quarter to new: a resting phase — weed, prune, harvest, turn compost and prepare beds.
Anglers' solunar rating: good — the tradition says fish feed hardest in the days either side of new and full, and around moonrise and moonset. The evidence is mixed; light and weather matter more.

Forces at work
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.
- Worth watching
The moon
Waning Crescent · 15%
Waning, 26 days old. Full moon in 19 days. Anglers' solunar rating: good (a tradition).
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.
- Worth watching
Wind
6 km/h now · 30 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.
- Working for you
Rain
47.5 mm / 7 days
47.5 mm across 5 days. About right; leave the hose coiled.
Sets the pace for everything: germination, fungal fruiting, slug nights, and how a river runs for the next three days.
- Worth watching
Soil warmth
8.2 °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.
- Quiet right now
Day length
11h 01m
Losing about 5 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.
- Worth watching
Frost
7 days
Average first fall frost is around Oct 14. 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.
