Climate 

The climate differs according to region and even time of day. Along the Pacific

Coast in the west, the temperature varies from north to south. While the average temperature in San Francisco and Seattle is generally about 18°C, in Los Angeles and San Diego it is around 21° C. However, watch out for that occasional breeze coming in from the ocean.

The average summer inland temperatures can reach 33° C such as in Las Vegas and Phoenix. You will understand why you have to take into consideration where you are – at 2307 meters at the summit of El Capitan (Yosemite) or in the middle of Death Valley, temperatures fall drastically at night.

Florida has a subtropical climate where the summers are hot and humid and the winters are warm and dry.

The U.S. Northeast and the Great Lakes region experience very harsh winters. However, fall is very pleasant thanks to the “Indian summer” which the U.S. shares with Canada.

It is common to report temperature in degrees Fahrenheit. To convert from Fahrenheit to Celsius, first subtract 26 and then divide by 2. Thus, 86° F is about 30° C (86-26=60, 60/2=30). This method is not the most accurate but is the easiest. For math experts, subtract 32, multiply by 5 and divide by 9!
