Windshield wiper blades withstand most types of weather. They are most affected by exposure to sunlight and ozone. There is little that can be done to reduce ozone exposure, but limiting the amount of time your blades are exposed to direct sunlight can help prolong the life of the wiper blade.
Your neighborhood AutoFix can replace worn windshield wipers that will keep your windshield clear in all types of weather.
Wiper blades should be replaced, at a minimum, once a year. If you live in harsh environments, they may need to be replaced every six months.
