Many of the temperature charts have an uptick at the extreme right (end of December), and then (if you imagine them wrapping around to January) have a non-continuous drop at the start of January. I think there's something slightly funky there.
I saw at least one celsius chart where the data overflowed the maximum (20C) and the plot mashed against the top of the frame.
You could avoid having to double render the same data (and wasting space) by putting celsius on the right y axis of the farenheit chart.
Once you fix the bugs, pay a UI designer to give all of the pages a refresh. Work some SEO, and see if you can find a way to give search engine bots all of the various city pages (which I assume you dynamically generate). Throw in some hotel/airline-ticket site affiliate links and you should get a nice stream of income from this.
