Green Canyon is an area in the Gulf of Mexico[1] that is rich in oil fields and under the jurisdiction of the Bureau of Ocean Energy Management.
[8][9] Block 185 of Green Canyon is known as Bush Hill and is a well known cold seep with a wide array of tube worms.
[12] As recorded by a station in Block 184, the air above Green Canyon has a tropical rainforest climate (Köppen climate classification Af), with warm winters and extremely oppressive summers and very low diurnal temperature variation year-round (especially in summer), expected for its location far from any landmasses.
Experiencing the purest Gulf influences possible, Green Canyon's summer nighttime low temperatures are some of the highest on Earth for any non-arid location, at least counting those on land.
The hot, humid air and warm water during summer and autumn can facilitate the development and sustainment of tropical cyclones, specifically Atlantic hurricanes, the water having surface temperatures above 26 °C (78.8 °F)—the typical threshold for tropical development—from May 25 to October 31 on average, and reaching a maximum of 30 °C (86 °F) on August 5.
