Denver
Explanation:
Denver, Colorado, is the city from the list that has the least chances to have a tropical wet/dry climate. This city actually has summers that are considered as mild, with the temperatures being in the the lower 30's C degrees, while the night temperatures drop to twice less than the daily temperatures. The winters on the other hand, are cold and snowy, which is not a trait of the tropical climates, but instead of the continental climate types, with the temperatures regularly being bellow the freezing point throughout the winter months.
Lava cools more rapidly above ground than it does underground because it's much colder above ground than it is underground, speeding up the process.
