Uttaranchal's diversity in terms of altitude means a corresponding
diversity of climate. And the range of temperatures is very wide
indeed, all the way from tropical to perpetually sub-zero. Low lying
areas, known as the Bhabhar plains (at the foothills of the Himalayas)
fall within the warm tropical zone, and the higher you go, the lower
the temperature goes- ranging, with increasing altitude, from sub-tropical,
through warm temperate, temperate and alpine to glacial and perpetually
frozen. Average temperatures range in summer from 30ºC in the
plains to 14 or 15ºC in the mountains (snowbound regions are
sub-zero throughout). Winter temperatures in the plains average
10 or 11ºC, and fall well below freezing higher up.
Most of Uttaranchal is effected by the south-west monsoon in the
summer months, and snowfall occurs in the mountainous zones.
Summer - cool during day and cold
Winter - snow bound and inaccessible
