The weather app for the whole trip
Knowday reads the whole camping window — how cold the nights get, when rain moves in, and how exposed you'll be — not just whether right now is pleasant.

What matters on a camping trip
How cold each night gets
The overnight low is what decides your sleeping bag, not the daytime high. Knowday reads the low *for each night* of the trip — so one cold night doesn't catch you in a summer bag.
Rain across the whole stretch
One wet night can sink a whole weekend. Knowday looks at rain over every day of the trip and rolls it up worst-night-wins — and tells you which night to pack the fly for.
Wind for staking out
A breezy night means staking the tent properly. Knowday reads the wind for each night so you know whether to pick a sheltered site.
Honest about the last night
The far end of a trip is genuinely uncertain. When a night runs past the forecast, Knowday says so — "still a guess" — instead of inventing a number you'd trust.
How it works
It treats the trip as a whole — scoring the day feels-like, each night's overnight low, wind, the rain chance over every day, humidity, and the moon for stargazing — then rolls it up so the roughest night sets the verdict, with a night-by-night breakdown underneath.
Two honest limits: dry-and-windy raises fire risk, but burn bans are the campground's call, not ours, and Knowday flags likely storms, not lightning — an exposed ridge in a storm is no place to be.
Camping is one of fourteen plans Knowday reads — walks and rides, the lawn, the garden, camping, the night sky, and the water.
