People who are relocating to the Phoenix area are sometimes uncertain about what clothing to bring to the desert. Should you throw away your winter coats and boots? Do people wear black in the desert heat? Does everyone wear sandals? What do people in Phoenix wear to work in the summer?
Do I Need Winter Coats, Scarves and Gloves?
In general, I wouldn't get rid of all your winter stuff. During the winter months we will have days that get down to the 30s at night, and there will be frost in parts of the Valley. In the winter, it is not unusual for us to have a 40° swing between nighttime and daytime temperatures, so some layering will be in order. Also, don't forget that we have serious weather just a couple of hours away, in case you take relatives to Sedona or farther north, like to the Grand Canyon.If you plan to visit certain relatives or friends often, or you travel for business, you will need those clothes. When my family still lived in New York, I kept a long raincoat, a down parka, gloves and a scarf at their place so I didn't have to travel with it.
Are There Different Company Policies for Attire in the Summer in Phoenix?
Some companies have summer wardrobe exceptions and that will vary with the company. Many companies allow women to dispense with the panty hose for the summer, and encourage slacks during those months. Cropped pants or capris are often not permitted.As far as men are concerned, companies often invoke a no necktie policy, and sometimes allow golf shirts in the summer, even though the dress code might otherwise call for suits. Many of our police and fire men and women have shorts as part of their uniforms. Many companies here in Phoenix have a more casual dress policy than in some large cities all year round, and casual Fridays, where jeans are permitted, are fairly common. You'll just have to check with your employer.
