Your temperature range is really not an issue, naturally cooler and more stable would be better - but I highly doubt temperature as your culprit. The 80+% humidity is fairly concerning, however. But I don't see it causing major issues unless you are using the board in the same environment. High humidity can cause condensation if you have large temperature swings/differences (ie, the boards in a cold room with the sun shining in on them...again unlikely). The proper way to store your boards would be in static protective bags and kept inside of a cool, dry, room.

If this is trapped into places like between ICs and the board, and has not evaporated at the time the boards is powered up, it can cause problems. . 80% humidity is very high, high enough so that you can be getting condensation on the board.
