Every month is different...
...May. The birds are back: waterfowl, singing birds, predatory birds. The ice on the lake breaks during the second half of the month (the snow has all melted by the end of April at the latest). It is relatively easy to see wildlife, because the trees don't have their leaves yet. Late sunsets create "golden evenings".
...June. Enjoy the bright evenings and nights! The lake is open, the vegetation is exploding, wildflowers are in bloom. Days may get pretty hot during the second half of the month.
...July. The nights continue to be bright. Summer has arrived! Fireweed, the Yukon territorial flower, is in bloom everywhere. The lake is warming up quickly and on a hot day invites you to a refreshing swim.
...August. During the first half of the month you can still go for a swim. The wild berries are ripening now. The nights are getting dark again from around August 10. Sunsets and clouds offer good photography opportunities.
...September. It's time for the beautiful fall colors and for sometimes spectacular skies. Days are warm, nights cool, you might see an occasional northern light. The second half of the month is a good time for watching wildlife.
