    Default Cold weather thermometer

    What do you folks use to check the temperature? I want something accurate below 0 but don’t want to spend a ton. Opinions? Reviews? Thanks.

    The Suunto Core off my wrist for a while reads down to -5F.

    I have a wireless sensor that connects to my watch. It’s about the size of three stacked quarters. All Garmin gear.

    The Kestrel Drop D1 hangs from your backpack and will log temps over an entire hike. Pretty cool little device.

    Digital meat thermometer. I have one which claims to go down to -58F.

    I use a cheap zipper tag thermometer/compass. It's accurate enough.

    I guesstimate

    Im a pretty good guesser.

    Usually within a couple degrees

    But real low humidity can fool me below freezing.

    Isn't the smartphones temperature sensor good enough?

    Not sure what the cold does to the charge state of the battery, but I've done it repeatedly for gear backyard testing in the sub-freezing regions without any problem.
    While it would be feasable during sleeping to keep the smartphone laying aside the sleeping bag, it would be more difficult during hiking.
    But then there are advantages doing it with the phone, as there are many apps that can do much more than just a simple display the temperature. There can be tracking of temp over the whole night, als well as a (virtual) drag indicator, and more.

    Thanks for all the intel. My sunnto watch seems to loose the screen around 2 degrees. Cell phone stay in the bag on a charger all night. I’m lucky to keep it powered during the day if it’s cold enough. I was looking at the cheap zipper ones but reviews say they can be 10-25* off and I can guesstimate better then that. I’ll looking into the meat thermometer but sounds bulky and sharp haha. I also have a house thermometer that’s very small and does inside/outside temp with a small whip that goes outside. I don’t know if something like that is worth it as it can stay inside the bag and the sensor can go outside. But then I see myself all wrapped up in it possibly.

    If the temps drop seriously, I can't imagine to take the additional hassle of wires going through the bag (either through the opening you breath through, or through the lower end of the zipper?).
    Its already a real task to wrap up yourself, including all the thermals, clothes, hat, balaclava, bag liner, take care of the bag itself, the drawstrings of hood and collar, take extra care to not slip off the pad, etc, and meanwhile still find some restful sleep.

    I'd rather suggest to get something cheap, standalone, analog, old-school for to get the outside temperature.
    My wife is famous for ice-swimming, and she got a cheap plastic thermometer she uses to get the water temp for the record of it.
    Something like this:

    Cheap enough to not go bankrupt if lost.
    If you need higher accuracy, you could compare the real-life values to a professional thermometer and note the difference.

    I did bring wireless thermometer on scout car camping years ago. Put part outside shelter, readout inside.

    This confirmed the temp gain in a tent. 1 p in 2 p tent was about 3 f. 2 p would be 5-7f.

    Kind of heavy for hiking though

    Walmart thermometer/compass. Compass is worthless, thermometer is fairly accurate.

    Buy a cheap zipper one and test it at home. If it is off 10-25* then get something else.
    If you don't stand for something, you will fall for anything.

    Some days, it's not worth chewing through the restraints.

    Same here. At zero degrees, give or take 5-10 degrees doesn't matter. Frickin' cold is frickin' cold.

    The one I bought at Walmart was within 1-2*F when I checked it against a quality thermometer at the house. For $2, I really can't expect more...

    Do you carry a thermometer to check how accurate your guesses are?

    Not very bulky and very light, 0.5 oz according to my scale. The probe is 5" long and pointy at the end, so you would want to put a piece of tape over it. But the long skinny probe makes it easy to attach somewhere on the pack.

    Same here. Mine has a Coleman logo and cost about a $ buck at Dick’s.
