Western America (region)
weather, climate and best time to visit


The climate of Western America is one of great diversity. West America runs from the west coast of America to the Rocky Mountains and everything in between. It is a huge area. If you make a tour here you can be walking in your t-shirt one day and standing in the snow in the mountains the next. Because the climate is so different in each region, we have highlighted some of the most popular destinations.

If you want to do a tour of the American national parks, it is best to plan it between May and October. Outside these months some national parks are sometimes closed due to the amount of snow that can fall here.

The west coast of America does not have to be visited for a beach vacation. It lies on the Pacific Ocean and the sea temperature here is very chilly for a dip in the water. If you're more into heat, the south is right for you. And can't it be warm enough for you? Then visit Death Valley, where the temperature in summer can reach over 50 degrees in some places.
