Lake Berryessa is in a valley, which traps air and makes air pressure higher. The valley's shape also blocks winds that could change the air pressure. In the summer, the air is dense and heavy, causing low air pressure. This brings hot temperatures. In the winter, the air is lighter and causes high air pressure, bringing cooler temperatures. Lake Berryessa has a Mediterranean climate, which means it has wet winters and dry summers. This climate type makes the air pressure switch between high and low throughout the year.
