Arizona known as the Grand Canyon state is in the south west of the United States and does not have a coast line. Arizona has an international border with Mexico to the south and is bordered by 4 US states, which are California to the west, Nevada and Utah to the north and New Mexico to the east. The state capital is Phoenix and this is also the most populated city. Famously, the Grand Canyon National Park is located in the north west of the state bordering on Nevada and many tourists take helicopter trips out of Las Vegas, Nevada to fly the rim of the Grand Canyon and then on to Flagstaff, Arizona where Route 66 passes. The state is in fact split in to 2 parts with regard to the climate, with deserts and very high temeratures in the south and the mountainous area with heavy snowfalls during the winter and numerous ski resorts in the north.
The climate of Arizona is one of very hot summers and mild winters in the south of the state, whereas in the north, summer is mild and the winter is cold. The all time record high temperatre in Arizona was 128f/53c at Lake Havasu City, where you can see the old London Bridge which was shipped out from London piece by piece in 1971 and then reconstructed. Annual rainfall in Arizona is about 13 inches.
A popular location for scuba diving in Arizona is centered around Lake Pleasant, with very pleasant surface temperatures, but drop rapidly as you descend. The water visibility is generally good, but can vary depending on the season. Other dive locations that are popular are the 45 mile long Lake Havasu and Lake Mohave, where there are various wrecks and the remains of a town. Many of the dive operators take the opportunity of organising trips to coastal areas of Mexico.
