With summer rapidly approaching, April tends to be a pivotal month in southeast Texas.
For one, it is the second driest month of the year along the coast in terms of total average rainfall. If the rains fail to materialize during the month, soil moisture can rapidly become depleted as warmer temperatures set in. For another, the bulk of the rain during the month will often come in one or two downpours. This, again, is less favorable for soil moisture and vegetation than when precipitation occurs at regular intervals.
