If you look at the average temperature for each day of the year, its amazing that it climbs and falls so smoothly. One degree down every 7 to 10 days from august to december and one degree up every 7 to 10 days from january to july.

The range for high temps bottoms out at 44 degrees on December 26-Jan 3rd

The range for high temps tops out at 81 degrees July 26th-Aug 5th

The important date is when the average daily high crosses 60 degrees. Thats when its warm enough to spend lots of time outdoors. picnics, bike rides, hikes, etc. That happens on April 11th.

So how can I be someplace warm between Jan 1st and April 11th?
