April sees a significant decrease in snow and rain in Crater Lake, but the average low temperature is 21.9°F (-5.6°C) and the nights are freezing.
The snowfall registers 45" (1143mm), while the rainfall is 5" (127mm), which are still heavy considering the increase in the sunshine to a daily 8 hours.
Ranger-led snowshoe walks are popular in the backdrop of the trails through the subalpine forests. For many people though, the nail-biting cold and large snow cover are enough to avoid a visit to Crater Lake during April.
