Tonight
Worth a lookFriday, September 25, 10 p.m. to 7 a.m.

Your spot sits in a hollow where cold air collects at night.
Best change
Move 20 to 50 meters higher, away from the valley floor or creek.
- On clear, calm nights it is often several degrees warmer there.
This is based on typical values for the gear types you picked, so treat it as an estimate.

What works tonight
The gear this night calls for, for someone who sleeps like you.
- Missing
Sleeping bag
Comfort 35°F or colder
Usually sold as a 26° bag. The number in a bag's name is the limit, not the comfort.
- You have this
Underneath you
R1.5 or more
The R-value says how well a pad keeps the cold ground out.
- Worth adding
Also useful
A bag liner
Adds a few degrees to the bag you already own.
Before you sleep
- Put on a warm layer and a hat before about 3 a.m., or go to bed already wearing them.
- Eat a proper meal with some fat before bed. Your body keeps burning it through the night.
- Pee right before you get in your bag. Getting out at 3 a.m. in the cold is worse.
- Sleep in dry clothes, not the ones you wore all day. Damp fabric pulls heat out of you.
- Your spot sits lower than the ground around it. On a clear, calm night cold air drains into spots like this, so expect it colder and wetter than the forecast. If you can, move a little higher up, away from the creek or valley floor.
- Bring shoes, clothes and electronics inside. Anything left out will be wet by morning.
How we estimated this
At the coldest hour (7 a.m.):
- Outside at your spot
- 44°F
- Warmth your shelter holds
- +2 °F
- Clear-sky cooling
- −2 °F
- Low spot
- −7 °F
- Air around you
- 37°F
- Your bag's comfort rating
- 39°F
- Cold ground through what you lie on
- +4 °F
- Your comfort limit
- 43°F
6 °F short, so you will likely be cold.
Assumptions
- Bag categories use typical ratings as sold: summer about 50 °F (10 °C), 3-season about 30 °F (-1 °C), winter about 15 °F (-9 °C). The number in a bag's name is usually its lower limit, so its comfort rating is about 9 °F (5 °C) warmer.
- What you lie on: foam mat about R2, thin air pad about R1.5, insulated pad about R3.5, winter pad R5 and up, van bed about R4, air mattress about R0.5. Colder ground needs a higher R-value.
- Shelters hold a few degrees early in the night and less towards morning. Wind and clear, calm skies take warmth away.
- Weather: Open-Meteo forecast for your spot, on a grid of a few kilometers, corrected to its height.
- These are rules of thumb, not measurements. People and gear vary.
A forecast, not a promise. Mountains, valleys and water make their own weather, so trust what you see and feel on site. Terms and liability
