June is a pretty amazing month to hike in Whistler.  The average low and high temperatures in Whistler range from 9c to 21c(48f/70f).  The summer tourist season in Whistler doesn’t kick into high gear until the end of June, so most trails remain relatively quiet.  The higher elevation hiking trails in Whistler and Garibaldi Park with have lingering snow well into June and sometimes early July.

July is a wonderful time to hike in Whistler and Garibaldi Provincial Park.  The weather is beautiful and the snow on high elevation hiking trails is long gone.  The average temperatures in Whistler Village range from 11c to 27c(52f to 80f).  Located in the Coast Mountains, Whistler gets warm summer days and cool nights.  On a hot July day of 25c(77f) often switches to a cool 12c(54f) night. 

August hiking in Whistler definitely has the most consistently great, hot weather.  You can feel the rare pleasure of walking across a glacier shirtless and still hot.  Even in the high elevations and on glaciers the temperatures are often a beautifully hot 20c plus.  There are numerous glaciers that are readily accessible via Whistler area hiking trails.  Wedgemount Lake has one of these beautiful glaciers just steps from its far shore.

September hiking in Whistler is possibly the best month of all.  The snow has melted far up to the mountain tops, yet the temperatures are still quite high.  And just like that wonderful phenomenon of May and June, there are no annoying bugs.  And with the passing of the first week of September, the summer season officially ends, so the number of hikers dwindles to virtually none by the second week.

Hiking in Whistler in October is often unexpectedly stunning.  The days are much shorter and colder but the mountains are alive with colour from the fall leaves.  On the higher elevations there is often a dusting of snow that makes everything look amazing.  Picking a full moon evening to hike in a place like Joffre Lakes, Russet Lake or Wedgemount Lake makes for an incredible night in the mountains.

November in Whistler is when the temperatures plummet and the first heavy snow falls in the alpine and often in Whistler Village.  The hiking opportunities become limited to easier and lower elevation hikes such as to Nairn Falls, Brandywine Falls and Rainbow Falls.  Waterfalls are a great in Whistler, huge and impressive.  Also, most can be accessed year-round. Alexander Falls, located high up in beautiful Callaghan Valley, just metres from a snow plowed road. 

December hiking in Whistler is mainly done on snowshoes, though if it hasn't snowed for a few days, trails to Whistler Train Wreck and Rainbow Falls can usually be tackled fairly easily without snowshoes.  The wonderful, multi-use trail network in Whistler, the Valley Trail is amazing on foot all winter, though the overlapping Sea to Sky Trail is quickly buried in December snow.  Some sections of the Valley Trail are snowplowed and some sections are groomed for free cross country skiing.

There are plenty of beautiful and free snowshoe trails in Whistler and Garibaldi Provincial Park.  From the surreal paintings of Whistler Train Wreck to the magnificent mountain serenity of Wedgemount Lake in Garibaldi Park.  Trails range from extremely easy, like the short, flat trails to Brandywine Falls and Rainbow Park.  To challenging and long trails to places like Elfin Lakes, Taylor Meadows and Wedgemount Lake. 

February is a great month for snowshoeing in Whistler and Garibaldi Park.  The days slowly get longer, but the temperatures stay consistently cold.  Expect several days of -12c and of course much colder in the mountains.  February is a great month for trying some overnight snowshoeing trips.  There are even several huts that are available to use.  Some are free and some have a reasonably low cost.

In the(usually) deep March snow of Whistler you have an amazing array of snowshoeing options.  If you have not been to the Whistler Train Wreck, you have to, it's a must see.  An incredible 50 year old train wreck, turned art exhibit, turned bike park.  It is an amazing surreal world hidden just a couple hundred metres from the busy Sea to Sky Highway, running along the spectacular Cheakamus River.

April in Whistler is a wonderful time of year.  The winter deep freeze ends and T-shirt weather erupts.  The village comes alive with overflowing patios and the excitement of approaching summer can be seen everywhere.  The snow in the village starts the month measured in feet and ends the month, having mostly melted, about halfway up to mid-station on Whistler Mountain.  Early in April the usual favourite places to snowshoe are warm and wonderful.

May is an extraordinarily beautiful time of year in Whistler.  The days are longer and warmer and a great lull in between seasons happens.  Whistler is fairly quiet in May and nobody goes hiking.  This is because most of the trails have quite deep snow.  This keeps everyone away, and for good reason.  The best Garibaldi Park and Whistler area trails are mostly steep and at high elevations, so hiking or snowshoeing in deep snow is exhausting.
