I suspect it's the moisture in the air that's as much a problem as the temperature. We see in the 400-700 nanometer range of visible light. Laser rangefinders operate in a higher frequency range but I can't find the exact numbers except one place mentioned a bushnell rangefinder using a 905 nm. I suspect most companies keep it proprietary. Water absorbs in the 1400 nm range so if their lasers are in that range then water could interfere with it. There's also refraction from the water vapor like your headlights on a foggy night, that's what the LRF is seeing with a lot of water vapor in the air just in a different spectrum.
In the end I suspect picking the LRF rated for the most distance is going to give you the best chance of it working in less than ideal circumstances.
