What works tonight
The gear this night calls for, for someone who sleeps like you.
- You have this
Sleeping bag
Comfort 40°F or colder
Usually sold as a 31° 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.
Before you sleep
- Stake out every guyline and point the low, narrow end of the tent into the wind.
- Rain is possible from about 10 p.m. Keep the rain fly on and bring shoes and packs inside.
How we estimated this
At the coldest hour (5 a.m.):
- Outside at your spot
- 40°F
- Warmth your shelter holds
- +2 °F
- Air around you

- Your bag's comfort rating

- Your comfort limit
- 39°F
3 °F to spare, so warm enough.
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
