Lake Great Test and Evaluation Climate General weather conditions at Point Mugu and San Nicolas Island and China Lake are highly conducive throughout the year to test and evaluation activities.
Temperatures are consistently warm in summer and mild in winter.
Due to the dry desert air of the Land Range, higher temperatures are bearable with pleasant, warm nights. Winters are very pleasant with lots of sunny days and temperatures that range typically from the 30s to 50s. Snow seldom occurs. The proximity of the cool Pacific Ocean waters results in cool summer days and nights. The climates are Mediterranean with mild temperatures.
