Temperature histogram

In commemoration of the coldest dive I have ever done in a wetsuit, this is a histogram of the water temperatures I have encountered throughout my 160+ dives. Red is for warm water dives (i.e. in a 3mm wetsuit or shorty) and blue is for cold water dives (7mm suit and hood).

At 5ºC, yesterday's dive was a full 3ºC below my previous low (~8ºC at Friday Harbor).
