Compared to San Francisco, San Jose has slightly different climate characteristics. San Francisco, being located on the coast, is influenced by a cool maritime climate, while San Jose, situated inland, tends to be relatively warmer and drier.

From June to September, the average high temperature in San Jose is about 28°C, with an average low of about 15°C, making it a bit warmer than San Francisco but still pleasant. This is due to the coastal fog and ocean breezes being blocked during the summer. However, other cities at the same latitude have cool and dry summer weather, making it suitable for outdoor activities.

The average low temperature during the winter months from November to March is about 5-10°C, and while there are many rainy days during this period, snow is rare, causing little inconvenience in daily life. Thanks to the mild climate, outdoor activities are possible even in winter.

  • San Jose is surrounded by mountains, which contributes to its inland climate characteristics, resulting in significant temperature differences between day and night.
  • Precipitation is concentrated in winter, and summers are very dry, with total annual rainfall being much less compared to Korea.

Thanks to its warm and pleasant climate, San Jose has established itself as a well-known area in Silicon Valley, characterized by a high quality of life and developed outdoor activities.
