Unlike many destinations, the communities in northwestern Arizona don't have distinct high and low seasons. The arid climate and clear winter skies attract "snowbirds," retirees flocking south to escape the harsh northern climes. On the flip side, the hot, sunny summer months attract sports enthusiasts looking to cavort in the cool, blue waterways—despite searing temperatures topping out in the 120sF.
Lake Havasu City plays host to hordes of college revelers during Spring Break in March and Kingman fills up fast during the annual Route 66 Fun Run in May. Things simmer down a bit during the spring and fall months—but not much! Overall, expect crowded weekends during the busy summer months and sold-out rooms during sporting events and fishing tournaments.
