The Bernese
Oberland Traverse
is likely to have the best conditions between mid-July and the end of the
August. Huts are generally open from mid-June until mid-September, which
defines the hiking season for this route. Note
that due to a limited operating season of the last hut on the route, it
is likely that we will need to make modifications to the standard
itinerary outside of their main operating season from July 4th to August
17th.
Due to rest days at the hotel on the last day, this itinerary cannot start on a Friday in July/August, or on Friday, Saturday or Sunday in June/September.
Here's what
conditions to expect at different times of year:
Late June:
Huts are open and routes from the valleys to the huts are clear. Problematic
snow is likely on the passes and at high elevations. There is a high risk of
not being able to complete the itinerary during this time. Even if the passes
are clear in time for your hike, they usually clear at the very last minute,
and June hikers always have a couple of stressful weeks leading up to their
hike as they eagerly wait for the snow to melt in time for their hike. In
almost every year, it is not possible to predict what trails are going to be
like in June until one or two weeks before. This is true even after a winter
with low snowfall.
July and
August: Problematic snow can remain on the route through the second
week of July, but it is less likely than in June. Summer settles in and days
are usually mostly sunny with an afternoon thunderstorm or two. These
thunderstorms rarely interfere with hiking itineraries and are not usually
problematic. Of course, thunderstorm safety should be practiced. The
wildflowers at the higher elevations should be all out by mid-July. Hiking
conditions during this time are often favorable, and it’s a great time to be on
the trail.
Early
September: The first snow of the winter usually falls in the
first week of September. The snow rarely sticks around for more than a day, but
the visibility can be very low, making navigation problematic, and maybe even
impossible, on this one day. Most days in early September are beautiful and
perfect, and the thunderstorms are less, but there is a higher risk of
snowstorms and conditions that may prevent you from completing your hike during
this time. Many hikers have incredible weather in September, but some do not.
It’s simply a matter of luck. The later you push into September, the higher the
risk that unfavorable conditions (usually snow, but sometimes extremely cold
temperatures) can interfere with your hiking itinerary. We notice that
customers who are on the trail beyond September 15th are much more
likely to quit their hike early due to conditions. In early September, the
wildflower season is mostly over, with the exception of brilliant bursts of
fireweed that mark the end of summer.
In all
months, it’s reasonable to expect 1 to 2 rainy days on the trail.
