Beverly Hills Weather: Your Year-Round Climate Guide

Typical Weather Patterns

Beverly Hills enjoys a Mediterranean climate, defined by mild, wet winters and warm, arid summers. Located in the heart of the Los Angeles Basin, the city benefits from a unique balance: it is far enough from the coast to avoid the most persistent marine dampness, yet close enough to escape the extreme heat of the inland valleys. On average, the city sees over 275 days of sunshine per year, with significant rainfall largely restricted to a few winter storms.

The Daily Rhythm

The climate typically follows a predictable diurnal cycle. Mornings often begin with a cooling marine layer (low-lying clouds or fog) that rolls in from the Pacific. This mist usually 'burns off' by mid-morning, giving way to bright, direct sunlight. As the land heats up in the afternoon, a sea breeze typically kicks in, moderating temperatures and capping the heat. Evenings are famously crisp; as soon as the sun sets, temperatures can drop by 15°F to 20°F (8°C to 11°C), making outdoor activities comfortable provided you have a light layer.

Seasonal Trends

• Winter (December – February): This is the "wet" season, though rain often falls in short, intense bursts rather than long periods of drizzle. Daytime highs hover in the mid-60s°F (18-20°C). While snow is non-existent, atmospheric rivers can occasionally bring record-breaking rainfall to the base of the Santa Monica Mountains.
• Spring (March – May): Known for its "May Gray," this transitional period sees the marine layer last longer into the day. Temperatures are mild, typically ranging from 55°F to 72°F (13-22°C), and the landscape is briefly at its greenest.
• Summer (June – August): The season begins with "June Gloom," characterized by overcast mornings. By July and August, the skies are almost perpetually clear. It is a dry heat, with daytime highs averaging in the low 80s°F (27-29°C), though occasional heatwaves can push temperatures into the 90s°F.
• Fall (September – November): Surprisingly, autumn—specifically September—is often the warmest time of year in Beverly Hills. This is also the start of the Santa Ana wind season, which can bring unusually hot, dry air from the desert.

Microclimates and Regional Variations

Beverly Hills is a masterclass in Los Angeles microclimates. The "Flats" (the southern, more urban part of the city) tend to be more influenced by the marine layer and stay slightly cooler. In contrast, the hilly sections to the north, nestled against the Santa Monica Mountains, can trap heat and often experience higher temperatures in the afternoon. During winter rain events, these hills can also receive significantly more precipitation than the lower areas due to orographic lift (clouds being pushed upward by the terrain).

Weather Phenomena: Santa Anas and June Gloom

The two most distinct local weather events are the Santa Ana winds and June Gloom.

• June Gloom: This is a persistent low-level stratus cloud layer that blankets the region during late spring and early summer. It creates a cool, damp feeling in the morning that can catch visitors off guard, even when the forecast says it is summer.
• Santa Ana Winds: These occur when high pressure over the Great Basin pushes air toward the coast. As the air descends through the mountain passes, it compresses and heats up, resulting in sudden, hot, gusty winds and extremely low humidity. This phenomenon can cause temperature spikes even in November or February.

Historical Context and Local Life

Locals experience the weather as a series of subtle shifts rather than dramatic changes. Historically, the area was much more prone to smog, but thanks to the sea breezes and improved air quality standards,
