For practical purposes, M is right. Technically, temperature does have a small effect on calorie burning--heat and humidity increase the amount of energy it takes to maintain your core temperature, but cold actually burns more calories because your body has to boost your core temperature, which takes a little more work. But in both cases, it's a very small amount.
The reason it feels much harder to exercise in the heat and humidity is because of heat stress. The humidity, especially, makes it harder for the sweat to evaporate, which is what actually cools you down. One good thing to do is to avoid wearing cotton or fabrics that absorb moisture, and wear one of those moisture-wicking fabrics, which will reduce the problem a little bit.
Hope this helps.
"All your life, you have just been waiting for this moment to arise." (Lennon & McCartney, "Blackbird")
You burn calories through activity, not through sweating. If you are doing the same workout, you will burn about the same calories, regardless of temperature.
Running on the shady side of the road, in early morning or late afternoon when the sun is low in the sky, etc, can all help reduce the effects of heat.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.

i went running today in the hot weather, about 80 degrees and really humid. i could only run for about 15 min with a 5 min warm up and cool down. i usually can run for about 20-25 min. i know we lose more water because we sweat so much, but do we burn more calories working out in the heat? i have searched the net and found conflicting answers...does anyone know for sure?
Finish each day and be done with it. You have done what you could. Some blunders and absurdities have no doubt crept in. Forget them as soon as you can. Tomorrow is a new day, begin it well and serenely and with too high a spirit to be cumbered with your old nonesense. -Ralph Waldo Emerson
