It means to be cool or to be "with the times"
"Cool" meaning "good" dates from the late nineteen-forties, when "hot" jazz went out of favor, replaced by "progressive" bop or bebop. Mop.
Cool beans means, "sweet" or "excellent" and "great". It started in the US from college slang in the 1970's. It could also be an updating of the expression from the 1850's of "some beans," which meant "excellent" or "awesome".
You can say that it is balmy or mild. Depending on how you use it, hot could even be a synonym. If someone says "it is getting warm in here," you could substitute hot. If you are referring to an in-between temperature, as with water, you could use tepid. If you are trying to replace it in the sentence "He received a warm reception," you could replace it with enthusiastic.
