I think you/we need much more information.

Are you really trying to build a model that predicts the temperature  
just given the time of day?

Given that you're in NY, I'd say 12pm in August sure feels much  
different than 12pm in February, no?

Or are you trying to predict what one sensor readout would be at a  
particular time given readings from other sensors at the same time?

Or ... ?
