Yes, you'll get wet but you probably won't get cold enough to risk hypothermia.
When the temperature is near or below freezing, you can't wait out the cold. It may warm a bit during the course of a day but the temperature is colder at morning and night. You can't sit under a tree and rest. Get caught in a cold rain...something we have to be very aware of here in Colorado even in the summer time ... and you can be in a lot of trouble very quickly.
Cold is still worse.
Are we arguing over whether hot or cold weather is worse? No comment on that but I can tell you for sure that it does get at or below freezing here, more than I care for, and a lot of that freezing rain that I can do without as well.
I don't think either condition is all that dangerous or difficult if you know what you're doing.
