Visalia has hot, dry summers and cool, wetter winters. Most rain falls from November through March. Summers often have clear skies and very little rain. Winter temperatures are usually mild during the day, but nights can be cold.
High pressure often settles over the area in summer. This brings sinking air, sunny skies, and dry weather. In winter, lower pressure storms move in from the Pacific Ocean and bring rain. Air pressure can also trap smoke, dust, and pollution near the ground when winds are weak.
Visalia sits in the southern San Joaquin Valley. The Sierra Nevada mountains lie to the east, and the Coast Ranges lie to the west. These mountains block much of the rain from reaching the valley, which helps make summers very dry. In winter, cool, still air can collect in the valley and cause thick tule fog, especially in the mornings.
The local climate is called a hot-summer Mediterranean climate. Spring brings warmer days and occasional rain. Summer is the hottest and driest season. Fall is usually warm at first, then becomes cooler. Winter brings most of the yearly rain, along with cool nights and occasional frost.
