Updated: 3/1/2026
May and June are the worst months for pollen. Grasses and weeds release pollen into the air. It's hard to avoid it when you're outside.
Summer brings relief from pollen. Most plants stop producing pollen by July. But some plants like nettle and sorrel still produce a little.
Autumn brings new pollen from weeds and grasses. It's not as bad as spring, but it's still a problem. By November, pollen counts go down, and the air is cleaner.
