In Falmouth, pollen seasons start in March with tree pollen. This is when trees like oak, birch, and hazel release tiny particles into the air.
Updated: 3/23/2026
In May, grass pollen takes over. This is the most common type of pollen and can cause problems for many people. It lasts until July.
Weed pollen starts in June and lasts until September. This type of pollen comes from plants like nettles and sorrel. It's not as strong as grass pollen but can still cause issues.
The good news is that pollen seasons end in September. By October, the air is much clearer, and people can enjoy the outdoors without worrying about pollen.
