On average, a hurricane measures 100 miles in diameter. The eye of the average-sized hurricane measures 30 miles in diameter. A hurricane is measured using the diameter of the hurricane and the wind speeds that it reaches.
The size and strength hurricanes varies immensely. A hurricane is measured using the Saffir-Simpson scale, which includes five different categories. Category 1 is the least dangerous hurricane, and it produces wind speeds of up to 95 mph. By contrast, Category 5 hurricanes are the most dangerous, with winds reaching over 157 miles per hour. Category 5 storms generally cause severe damage to the impacted area.
