Weather
The weather in autumn consists of a mixture of clear, sunny days and some patches of rain. Snow will begin to fall towards the end of November, but will not stick to the ground until early December, in winter. In, thunderstorms will dissipate around September, giving way for regular rain.

In September, (specifically the 8th in ) trees will begin to turn from bright green to a dull, musky green. In October (the 17th in ), trees will then turn a bright orange/brown color. Grass follows the same color pattern as trees, by turning a dull green color in September, then a dull purple in October. In November, the grass becomes a very dull pinkish-gray, and then in December, the ground, weeds, and clover all turn gray. Dandelions will disappear until next summer. The trees will often gradually change color.
