We are in a drought in Texas. Texas seems to go through cycles of drier and wetter patterns. Some years are wetter than others, while others are drier than usual. Upper Texas Coast is no stranger to that as I can attest living there. So, I made a chart of annual rainfall differences to see if there is a cycle. It is based on annual rainfall minus average rainfall. The data is from the Divisional Weather Set.
Average Rainfall For Upper Texas Coast (1895-2010)
Standard Deviation (1895-2010)
36.54 or below
58.48 or above
Here is graph that shows the dry and wet cycle for Upper Texas Coast.
Dry and wet cycles are about equally common, but dry cycles tend to last longer than wet cycles. Currently, we are in dry cycle, which started in 2008 and is currently going on. Dry or wet spells are not free of wet or dry months. Even in the driest cycle, there are heavy rain and flood events, while in the wettest cycle there are really dry months. It is all about how much rain fall in a whole year or years. It is feast or famine for us Texans. In many ways, it is a constant tug-of-war of rain or drought. We are always one notch away from drought.
