The Science Behind Activity

Snake activity is heavily driven by weather conditions, not just large-scale seasonal changes such as the shift from Winter to Spring or Summer to Fall. While time of year has an impact on snake activity, it’s primarily driven by various meteorological factors including, but not limited to, surface/air temperature, cloud cover, humidity, and more.

Placer Snake Removal’s weekly snake activity forecast combines large-scale seasonal trends, in addition to & perhaps more importantly, daily weather conditions. Since northern California’s weather conditions vary significantly based on geography, activity forecasts are available for 6 different regions of interior northern California.
