A good indicator of the wind in Squamish can
be identified in the temperature gradient from Vancouver (cooler) to Squamish
(warmer) to Lillooet (hot).
There does not have to be a huge difference in temperature for the wind
to blow, but the greater the difference the stronger the wind.
This gradient is usually established by 10
or 11 in the morning and builds through the
day.
Another indicator of smooth wind is no cloud in the
Webcam shots below. Cloud in the south and north often means more gusty
conditions.
