I did not doubt OP when he said it was due to high elevation, strange as it may seem. Makes for a much more interesting problem.

I spend a lot of time at Lake Tahoe, which is about 6200 feet above sea level, 3 psi less atmospheric pressure than at sea level, and water boils 12F lower than it does here at home (2F per 1000 ft is a good rule of thumb), so my coffee brews a little colder up there. Of course not knowing what altitudes are involved for OP, ...
