What to Pack for December in San Diego

Packing for San Diego's December climate requires a bit of versatility due to the range in temperature between day and night. Layering is key to staying comfortable throughout the day. Consider packing lightweight clothing that can be easily added or removed as needed. T-shirts, long-sleeved shirts, and sweaters are all good options. A light jacket or coat is essential for the cooler evenings and potential rain showers. Don't forget to bring a hat and scarf for extra warmth, especially if you plan on spending time outdoors in the evenings.

Sunglasses and sunscreen are essential items to pack for San Diego's sunny December weather. The sun can still be quite strong, even in winter, so protecting your skin and eyes is important.
