What to Wear in Long Beach in December
In December, Long Beach averages 49–65°F with about 5 rainy days and the mild Southern California winter that keeps the waterfront accessible and comfortable year-round. The Pacific Ocean breezes make the Long Beach waterfront 5–8°F cooler than inland areas, so a proper jacket is needed for Shoreline Village and waterfront dining even on mild December afternoons. Winter rain in December is more likely than any other month — a compact umbrella is a practical accessory.

Planning your December visit to Long Beach? Anticipate a mild, pleasant climate, perfect for exploring without extreme weather. Daytime temperatures typically range from the low to mid-60s Fahrenheit (16-19°C), offering comfortable conditions for outdoor activities. However, evenings and early mornings can be quite cool, with temperatures often dropping into the mid-40s to low 50s Fahrenheit (7-12°C), particularly near the coast where a gentle breeze can amplify the chill. While December is part of Southern California's "rainy season," significant downpours are infrequent; expect a few days of light rain or occasional showers rather than prolonged wet spells. The skies are often clear or partly cloudy, frequently breaking through any morning fog to reveal sunshine. The key to dressing comfortably in Long Beach in December is strategic layering. Start with long-sleeved tops or light sweaters that can be easily shed or added. A versatile medium-weight jacket or a stylish trench coat is essential for cooler evenings and mornings, providing warmth without being overly bulky. Opt for comfortable jeans, stylish trousers, or even thicker skirts with tights. Closed-toe shoes like ankle boots or fashionable sneakers are ideal for walking and will keep your feet warm. Don't forget a scarf; it’s a practical accessory for the evening chill and can add a pop of style. While sunshine is common, pack sunglasses for bright days and consider a light umbrella or water-resistant layer just in case of an unexpected shower.
