Mean annual precipitation ranges from 36 to 44 inches. The mean annual temperature ranges from 70 to 72 degrees F. Frost free days range from 280 to 300, and the elevation ranges from 10 to 100 feet above sea level. Thornthwaite annual P-E indices range from 46 to 60. These include the competing Bacliff and Francitas series and the Dacosta , Edna , and Faddin soils. Bacliff and Francitas soils are on lower slightly wetter positions.
Dacosta soils are on slightly lower or similar positions.
Edna and Faddin soils are on similar positions. Dacosta, Edna, and Faddin soils have loamy surface layers and argillic horizons. Laewest soils are moderately well drained. The permeability is very slow. Water enters the soil rapidly when it is dry and cracked, but very slowly when the soil is wet and the cracks are sealed.
