The Climate of Loomis

An additional microclimate is formed in the Loomis Basin due to the surrounding foothills, which block off many of the occasional summer, hot north winds. Added to the cause of a microclimate is a slightly higher elevation in Loomis, than the valley floor, and the surrounding forests of Interior Live Oak, Cottonwood, Digger and Ponderosa Pines.

When maritime influences are not present, the climate is more like interior Southern California, only much cooler. This due to a more northerly latitude and westerly longitude. Also, the Pacific Ocean near Loomis is both to the west and south, allowing more cooling ocean humidity into the area. Desert Southwest monsoons rarely effect Loomis in summer. To summarize summer, it's a good time for most meteorologists to take a vacation, unless there's a heat wave. Many are found on golf courses from 4:45 AM till 9:30 PM PDT.

The second type of winter storm comes from the Gulf of Alaska. These are much colder storms than the first type. Snow levels can fall as low as 500 feet elevation. When this happens many foothill, and mountain roads close or have snow-chain tire requirements on vehicles. However, while Loomis's neighbor, Auburn, nine miles to the northeast might have accumulations of snow, Loomis will only see a flake or two. This is due to our lower elevation than Auburn.

The third type of winter storm comes from Canada and is rare. These are very cold. When they manage to make it across the barrier mountains to the east from Idaho, Montana and Nevada, snow can fall as low as the Sacramento Valley floor. If these systems bring clear weather, freeze warnings are a sure bet for the long, winter overnight hours.
