For a while I've been looking for somewhere easy to read historic weather averages between two locations and last night it hit me, Wolframalpha! This was a success.

I would now like to be able to somehow search for the following type of query

Yearly weather averages for City X, compare city x and list other cities with similar results. The results should take into consideration northern and southern hemispheres, i.e. December in Southern Hemisphere may be average 30 Degrees C, but December in Northern might be -10, however in June you might get 30 in the northern hemisphere, and therein, December and June should be compared against eachother, not December and December. Basically, the query needs to be able to take into account the current season of the average temperature which has been recorded.

Is there a way to do this?
