What to wear to San Francisco and Las Vegas in March?

San Francisco can wear thin down or thick coat and rain gear in March.

San Francisco Peninsula is surrounded by water on three sides, which is affected by the cold current in Pacific California. San Francisco is a typical cool summer Mediterranean climate. Due to the long-term influence of sea breeze, the daily maximum temperature in summer in San Francisco is usually only about 20 degrees Celsius (℃), and it will exceed 30 degrees Celsius only for about one week every year due to strong land breeze. September is the warmest month. At the same time, because the water temperature in the Pacific Ocean is always between 10- 15℃, it may drop below 10℃ in midsummer. Because San Francisco is close to the seaside and the Golden Gate Strait, it is often affected by fog in the middle of the night and in the morning, but there is little rainfall in summer, and the rainy season is 1 to April. Although it is cold in winter, there is little snowfall.

Las Vegas can wear an ordinary coat in March. Due to the large temperature difference between day and night in the desert, pay attention to cold protection.

Las Vegas is located on the edge of Nevada desert in the United States, surrounded by mountains of1000-3000m. Las Vegas has four distinct seasons. Summer is a typical desert climate, and the temperature at noon is often as high as 38゜C, and the highest can reach above 45℃. The temperature is cooler at night. There are frequent thunderstorms and the temperature is above average. The winter climate is mild and suitable, and the average temperature during the day is about15 ゜ C. Although very hot weather occasionally occurs, spring and summer are still the most pleasant seasons. Las Vegas is rarely attacked by bad weather, and it is one of the regions with the lowest relative humidity among all the big cities in China. Surrounded by desert, it's as dry as death valley.
