The name Circumvent is derived from the monsoonal winds which gradually shifts each month. The prevailing winds on the Winter Solstice is directly north, then it shifts clockwise, shifting to directly south by the Summer Solstice. It continues to shift clockwise until arriving north again at the Winter Solstice. Circumvent is geographically located on an island on the 42nd parallel, with tall mountains to the west and northwest, and the Pacific Ocean the other directions. This, combined with the shifting winds, results in the experience of four very distinct seasons.
Circumvent has a subtropical "highland" (Koppen classification: Cwb) climate, bordering on humid subtropical (Cwa) and oceanic (Cfb). Circumvent lies in the USDA Plant Hardiness zone 8b.
