Like other inhabitants of the greater Los Angeles area, residents have a particular terminology for this phenomenon: the "May Gray", the "[[June Gloom]]" and even "Fogust". Overcast skies are common on June mornings, but usually the strong sun burns the fog off by noon. In the late winter/early summer, daily fog is a phenomenon too. It happens suddenly and it may last some hours or past sunset time.<ref>{{cite web|url=http://www.santabarbara.com/community/weather/junegloom.asp| title = Santa Barbara.com: June Gloom| publisher=SantaBarbara.com| access-date=August 13, 2009}}</ref> Nonetheless, it will sometimes stay cloudy and cool all day during June, even as other parts of the Los Angeles area experience sunny skies and warmer temperatures. At times, the sun can be shining east of 20th Street while the beach area is overcast. As a general rule, the beach temperature is from 5 to 10 degrees Fahrenheit (3 to 6 degrees Celsius) cooler than it is inland during summer days, and 5 to 10 degrees warmer during winter nights.

It is also in September that the highest temperatures tend to be reached. It is winter, however, when the hot, dry winds of the [[Santa Ana wind|Santa Anas]] are most common. In contrast, temperatures exceeding 10 degrees below average are rare.

The rainy season is from late October through late March. Winter storms usually approach from the northwest and pass quickly through the Southland. There is very little rain during the rest of the year. Yearly rainfall totals are unpredictable as rainy years are occasionally followed by droughts. There has never been any snow or frost, but there has been hail.

Santa Monica usually enjoys cool breezes blowing in from the ocean, which tend to keep the air fresh and clean. Therefore, smog is less of a problem for Santa Monica than elsewhere around Los Angeles. However, from September through November, the Santa Ana winds sometimes blow from the east, bringing smoggy and hot inland air to the beaches.

The hottest temperature ever reported in Santa Monica was {{convert|100|F|C}} on November 1, 1966, while the lowest is {{convert|33|F|C}} on March 1, 1945, and again on March 21, 1952. The highest minimum temperature is {{convert|72|F|C}} on October 24, 2007, and the lowest maximum temperature is {{convert|51|F|C}} on 4 dates in February 2001 and again March 10, 2006. The snowiest months on record are January 1954 and March 1955, both with trace amounts. They are the only months to ever report snowfall. Many months have reported no rainfall at all. Conversely, the wettest month on record is January 1995 with a total of {{convert|17.82|in}} of rainfall. The wettest year on record is 1998, with a total of {{convert|25.4|in}} of rainfall; the driest is 1989, with a total of {{convert|4.04|in}} of rainfall.<ref name = NOWData/>
