I don't struggle to much with what clothing to take, it's the other stuff I have a problem with.
70's don't sound to bad. If you spending 2 nights then I would take at least 3 pair of socks. I always like to have a clean pair of socks when I crawl in my bag at night. 2 pair under wear. Not including the pair I wear when I leave for my trip. Socks and underwear take up little room. If I leave for trip with pants on I might take another light weight pair and a pair of shorts. I would take 1 or maybe 2 T shirts other than what I wear when I leave. A thin rain suit. A light jacket, rugged pair of tennis shoes, pair of sandals and maybe a pair of boots. Sometimes I leave an extra change of clothes in vehicle, so I feel more comfortable on way home.
Everything depends on the weather conditions, and if your taking vehicle, watercraft, or hiking.
One thing I always take is a wool army surplus blanket. I find it very comfortable to wrap up in when sitting outside if I feel cold.
