How committed is the rain?

38" is a medium amount of rain. In the UK, the S.E gets 20", the SW: 30-40", and NW, 40-60"
When does the rain fall?
In NW, it can rain hard, all day, for days on end. In SE, we get those rainy days once or twice a year, sometimes never.
How frequently and hard does it rain during commuter hours? We seem to get rain in early afternoon, which clears up by 5:00 commute. Rain often falls as light, but steady.

Rain becomes easier to handle if you are equipped with fenders, good waterproofs, rain socks or boots etc. Cool rain is easier than warmer summer rain since you don't overheat. Really cold rain, just above freezing, is horrible but rare. If it is that cold, it is usually dry.
