Tonight

Worth a lookFriday, September 25, 22:00 to 07:00

Cold from below: pad

Your setup looks borderline for this night

You may feel chilly from around 03:00.

The cold comes from underneath: your pad does not insulate enough from the ground.

Best change

Add insulation underneath until you have about R1.5 in total (estimate).

A closed-cell foam mat under your pad adds about R2.
Folded blankets or spare clothes help if you have nothing else.

This spot sits about 39 m below the land around it. On clear, calm nights cold air pools here, so expect it colder and wetter than the forecast.

What works tonight

The gear this night calls for, for someone who sleeps like you.

You have this
Sleeping bag
Comfort 4°C or colder
The comfort rating on the label, not the limit, which is about 5 °C lower.

R1.5 or more
The R-value says how well a pad keeps the cold ground out.

Stay safe from carbon monoxideNever run the engine or use a propane or gas heater inside a car, van or tent to stay warm. Carbon monoxide builds up while you sleep and can kill without waking you. Stay warm with layers, insulation and a hot water bottle instead.

Before you sleep

Put on a warm layer and a hat before about 03:00, 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 03:00 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.
Open the tent vents and keep the door zip open a bit at the top. Some condensation inside is normal on a night like this, so bring a small towel to wipe it off.

How we estimated this

At the coldest hour (07:00):

Outside at your spot: 6°C
Warmth your shelter holds: +1 °C
Clear-sky cooling: −1 °C
Low spot: −2 °C
Air around you: 4°C

Your bag's comfort rating: 4°C
Cold ground through what you lie on: +2 °C
Your comfort limit: 6°C

2 °C 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

Checked for a double-wall tent, a 3-season bag and a thin air pad. Check your own gear here.
