Before I go on a weekend trip, I look at the weather forecast in the nearest town to get an estimate for the temperature where I'll be backpacking. Trouble is, there often a big difference in elevation, not to mention weather patterns can sometimes very wildly depending on the landscape. Has anyone figured out a reliable way of estimating the temperature for a trek before actually hitting the trail?
I've heard that dropping 1000 ft equates with a 4 degree F rise in temperature, but that's totally unsubstantiated...
I hope all is well out there.
