Given that the number of wet days ranges from 6 to 14 per month throughout the year (with rainfall between 1 and 5 mm), a compact umbrella or a light raincoat will be a useful addition to your luggage in almost any season. The principle of layering your clothes is your best ally: a light jacket, windbreaker, or cardigan will come in handy for cool evenings or changeable weather.

Regardless of the time of year, comfortable walking shoes are a must-have for any traveler wanting to explore West Des Moines and its surroundings. Since the weather can be fickle, especially during the shoulder seasons, being able to easily add or remove layers will keep you comfortable throughout the day.
