1. Louisville, Kentucky
Sometimes there is a price to pay for living in such a beautiful city. Louisville may bring tears to your eyes with its high pollen count. Kentucky bluegrass is the top offender for allergy sufferers as it produces more pollen than any other grass in the United States. Be mindful when going for your morning walk as this is peak time for pollen to be released. It may even be worth your while to wear a mask if you’re overly sensitive. The pollen here spikes in late spring and early summer months, making Louisville the worst place to live with allergies for two years in a row.
