When is the best time to go to California?

The best time to visit California extends from March to November. Indeed, the diversity of tourist attractions and activities that can be practiced there makes this destination one of the most popular in the United States, almost all year round.

The choice of your travel dates will mainly depend on what you want to do and see on the spot:

  • To explore the national parks of the West, such as the famous Yosemite or Sequoia, it is ideal to go between May and September, when snow is not present on the mountains and temperatures are perfect for hiking or other outdoor activities.
  • To visit Death Valley, go in spring or autumn. During the summer season, temperatures are extremely hot, even dangerous, while in winter, biting cold and even snow are part of the landscape.
  • For a sunny holiday along the 1300 km of the Californian coast, it is best to go in summer, between June and September. You can fully enjoy the beach and, why not, try surfing, a very popular activity in the region!
  • For a city trip in one of the mythical Californian cities, a trip is possible all year round, especially in Los Angeles, San Diego. However, July and August experience a peak in attendance that can deter many, while in winter, the northern part of California, around San Francisco, is quite cool and humid. Therefore, prefer spring and autumn for an unforgettable stay exploring Hollywood or the Golden Gate Bridge!
  • To attend the grape harvest and go on a wine trip, autumn is ideal. The San Francisco region and Napa Valley are renowned for their magical colors.
  • When to go to California to see whales? Two periods are suitable: between June and October to observe blue whales and from December to May to admire gray whales. Apart from a boat trip, the best spots to see them from the mainland are in Santa Monica, Monterey, Mendocino, or Santa Barbara.
  • For skiing or other winter sports in the Sierra Nevada resorts, go to California between November and March. Some resorts even stay open until April, depending on weather conditions. Although very popular, the Christmas period there is truly magical.

Climate and Weather in California

If the region is so attractive, it is because of the diversity of its relief and landscapes. From the peaceful coasts to deserts where the altitude can be lower than sea level, passing through the Sierra Nevada with Mount Whitney reaching 4421 m, all of this greatly influences the weather in California.

In general, it is always cooler at higher altitudes than along the coast, and deserts experience very large temperature variations between seasons, as well as between day and night.

Thus, the climate of California varies from one locality to another and from one latitude to another. Here are the main trends:

  • A predominantly Mediterranean and temperate summer climate covers 74% of California's territory. It can be found, for example, in Los Angeles, San Francisco, or Sacramento.
  • A Mediterranean and hot summer climate is more prevalent as you move inland. This is the climate that prevails in Palm Springs.
  • Elsewhere, the climate is occasionally semi-arid or arid depending on the area. For example, there is a dry and cold steppe climate in San Diego, while it is more dry and hot in the Anza-Borrego Desert State Park. In Death Valley, there is a cold and dry desert climate, but make no mistake, summers there are scorching!

It is also worth noting that the temperature of the water in the Pacific Ocean varies greatly depending on where you are on the coast. While it can easily reach 22°C (72°F) in Los Angeles and San Diego in the heart of summer, it rarely exceeds 16°C (61°F) on the San Francisco side during the same period.

Climate of the Northern California Coast

The northern coast stretches from Big Sur, just below San Francisco, to the Oregon border.

The climate conditions of this part of California are characterized by mild winter temperatures and spring-like summer highs.

The small temperature difference between seasons makes the climate rather pleasant, especially as one can enjoy good sunshine from April to September. In winter, temperatures range between 15 and 17°C (63°F) , while in summer, it is rare for the thermometer to exceed 24°C (76°F) . Regardless of the season, it is very cool at night. Expect average lows around 10°C (50°F) from November to April and around 15°C (59°F) the rest of the year.

However, some days see the rise of fog, which can persist for a good part of the day, especially during the summer season from June to September. Rain, on the other hand, is frequent in winter, from mid-December to February.

Climate of the Southern California Coast

From Big Sur to Mexico, the climate of the southern Californian coast translates into mild winters, hot summers, and very pleasant shoulder seasons.

From December to March, the average daytime temperature is 20°C (68°F) . In April, May, and November, highs are around 23-24°C. The mercury really rises between June and October, with temperatures ranging between 26 and 30°C (86°F) , with August and September being the hottest months of the year.

In terms of precipitation, it is almost non-existent from April to November, and slightly more pronounced from December to March with about 3 rainy days per month. January is the wettest month, but monthly rainfall rarely exceeds 100 mm.

Climate of the California Inland

As soon as one moves away from the coasts and the impact of the ocean, the climate conditions are strongly influenced by the surrounding relief.

For example, in Palm Springs, the climate is hot, dry, and almost always sunny. It ranges from 30 to 35°C (95°F) from June to September, around 20°C (68°F) in the shoulder seasons, and an average of 17°C (63°F) in winter, from December to March.

From June to September, temperatures can become unbearably hot, with heat peaks in Death Valley like in Furnace Creek113°F) . It is better to explore these areas during the rest of the year, avoiding December and January if possible, as they are quite cool, around 16°C (61°F) . Our favorite months are March and April, when wildflowers are in full bloom and temperatures are idyllic, with averages around 25°C (77°F) .

Climate of the Mountains in California

The climate in the Sierra Nevada is characterized by significant temperature variations between seasons, even during the same day. The seasons are very distinct there:

  • In winter, from December to March, it is cold, between 0 and 5°C (41°F) , and snows heavily. It is essential to have chains or snow tires if you plan to go there during this period.
  • Spring, from March to June, is often cool. It is not uncommon for snow to linger in Yosemite or Lake Tahoe until late April. Temperatures usually rise above 10°C (50°F) in May and reach around 15°C (59°F) by the end of the season in June.
  • In summer, temperatures range between 20 and 25°C (77°F) depending on the regions, but nights remain quite cool.
  • Fall is characterized by a rapid drop in temperatures from early October, with averages around 14°C (58°F) and occasionally, the return of snow. This creates a magnificent spectacle of nature when trees are adorned with colorful foliage, reminiscent of the forests in eastern Canada. From November, winter weather conditions are already present: temperatures range between 3 and 10°C (50°F) .
