Seasonal Weather Patterns
Seasonal weather patterns have a dramatic impact on the health of your foundation. Spring and autumn, on average, have more rainfall than summer and winter (see rain chart below). Also keep in mind that in the summer the warm air can hold more moisture (humidity) and therefore less moisture on the ground. In winter, the air can hold less water so more water is on the ground.
This is why your skin feels dry and your lips get chapped in the winter, because there is less moisture in the cold air to re-hydrate your skin. Because the weather in our area is constantly in flux you should factor it in when developing a customized irrigation schedule.
