The problem with western NY weather (I'm in Rochester) in the winter is that we can get months where we see the sun no more than 18% of the time, owing to the extensive cloud cover coming off Lake Ontario (that is also what gives us the average 100+ inches of snow every winter - Buffalo, Rochester, and Syracuse all vie every year for the Golden Snowball Award, given to the upstate city with the most snow - Syracuse usually wins, actually.)
The weather on the north side of the lake, say in Toronto to Ottawa is totally different than the south side. Climate-wise, the lake buffers our weather from extremes - most winters see an average low temperature here of 10 degrees (but we can get into the minus digits occasionally).
But it is DEPRESSING. Like this past week. I am in energy depletion mode... just feeling blah. It's definitely a sun thing because I notice the Seasonal Affective Disorder which happens when there is insufficient sunlight. I was contemplating getting one of those natural light lamps, but winter this past year was basically cancelled (we had an extremely warm winter), so it didn't bug me as much.
The heat just turned on... AIGH... and now it's 49, but the sun has finally come out... at 6pm. Same pattern as every day for the last eight or so.
