Editing Mission Viejo, California (section)

===Climate===
Mission Viejo enjoys a borderline [[semi-arid climate|semi-arid]]/[[Mediterranean climate]] ([[Köppen climate classification]] ''BSh/Csa''), with mild temperatures and plentiful sunshine year-round. Rainfall totals, which average around {{convert|14|in|mm|abbr=off}} annually are focused primarily in the months from November to March. Summer is very dry and virtually rainless. Due to the city's proximity to the ocean, nighttime and morning clouds are fairly common, especially in May and June, a weather phenomenon commonly known as [[June Gloom]] or May Gray.

Like most of Southern California, the city is prone to dry [[Santa Ana winds]], bringing hot air from inland and punctuating the normally mild temperatures with noticeable jumps. For example, temperatures have reached highs of {{convert|90|°F|°C|abbr=on}} and above throughout many months of the year, occasionally into autumn. From 2012 to 2016, California experienced the worst drought in a century. In 2016, California experienced more rainfall than expected and ended most of the drought. Orange County was the last to have drought restrictions lifted.
