Understanding Pollen Allergies: Types and Timing

Pollen allergies affect millions of people. Knowing the types of pollen and when they occur can help manage allergies. We’ll explore tree, grass, and weed pollen and their seasons.
Tree Pollen: January to June
Tree pollen is a big problem for seasonal allergies. Trees like alder and maple start pollinating in January. By April, pollen counts are very high, with trees like pine, mulberry, and willow being the worst.
Tree pollen season is tough because it starts in early spring. This is when many people are outside. Knowing this can help you get ready.
Grass Pollen: May to September
Grass pollen becomes a big problem in summer. It starts in late spring and goes into early summer.
Grass pollen comes from many types of grass. It can cause serious allergic reactions. May and June are usually the worst months, but it depends on where you are and the weather.
Weed Pollen: August to November
Weed pollen is also a big allergen. Plants like ragweed are known for their allergenic pollen.
Ragweed pollen is bad because it travels far. It can cause symptoms even if you’re not near the plants. Weed pollen season starts in late summer and ends with the first frost.
| Type of Pollen | Typical Season | Peak Months |
| Tree Pollen | January to June | April |
| Grass Pollen | May to September | May-June |
| Weed Pollen | August to November | September |
Knowing about pollen types and seasons can help you manage your allergies better.

For those with allergies, knowing the pollen calendar is key to managing symptoms. Pollen season changes a lot depending on where you are. Understanding the monthly changes helps you prepare and take steps to protect yourself.
January-February: Early Tree Pollen Begins
In the early months, tree pollen starts to rise, mainly in warmer areas. Cedar pollen is very high in the South during this time. Knowing this early start helps you start your allergy management early.
March: Tree Pollen Intensifies
March brings higher tree pollen counts, making allergy symptoms worse. It’s important to watch local pollen forecasts closely during this month.
April: Peak Tree Pollen Month
April is the peak month for tree pollen. Allergy sufferers need to be extra careful, using medication as directed and staying indoors when pollen is high.
May-June: Tree Pollen Ends, Grass Pollen Peaks
