Climbing Season in Peru
If you are willing to practice mountain
climbing in Peru you should read carefully the following
May to September: The only time of year for high-altitude
mountain climbing. The dry season coincides with winter
in the Southern Hemisphere, which due to Peru's proximity
to the Equator, means 30-50 minutes of daylight less
per day. Temperatures drop below freezing at altitudes
over 4,500 meters. July is the best month for climbing,
as stiff northern winds start gusting in August.
September to December: This is a good time of year for
climbing smaller mountains and for trekking. This season
is the equivalent of spring in the Southern Hemisphere.
It is a time of gentle spring showers, generally after
midday as a result of clouds gathering in the morning.
Rain showers, sometimes accompanied by electric storms,
tend to peter out within minutes before giving way to
clear skies and starry nights.
December to May: The rain season. It rains heavily nearly
every afternoon for two or three hours, although there
are occasionally lighter and more drawn-out showers.
Like the season just before it, most precipitation falls
in rainstorms. This season is not apt for climbing.
Only on days when it does not rain is it possible to
walk through any of the gullies. Streams, while nearly
entirely dried up during winter, eventually become impossible
to cross during this season.
