Rainfall for March 2022. This March is officially the rainiest March since our records start in 1994. We recorded 9.96 inches, which is three times the prior average of 3.33 inches. The addition of this month actually raised the average March rainfall to 3.56 inches. Looking ahead, April is traditionally the driest month of the year, with an average of 1.44 inches. In 2011 and 2020 we recorded absolutely no rain in April on the island. We should get some next weekend, so our trend of wetter than average weather should continue.
