AccuWeather Global Weather Center – March 20, 2024

 

Pollen levels are on the rise across most of the United States, leaving many seasonal allergy sufferers sneezing and sniffling.

 

AccuWeather expert meteorologists say weather patterns and trends will contribute to a longer and more intense allergy season in 2024.

 

“This year will start off much earlier than most years in the East,” said

AccuWeather Senior Meteorologist Alan Reppert. “We could look at things to

be a full month ahead of normal with tree pollen, and still ahead when grass

pollen starts.”

 

Allergy experts track three key factors throughout the year; tree pollen, grass

pollen and weed pollen. Seasonal allergy sufferers may have different

reactions to different types of pollen, so knowing when pollen counts peak

can be useful for managing symptoms.

 

Reppert warns that it could be a bad year overall for seasonal allergies in the

eastern United States starting in mid-spring through the end of summer.

Tree Pollen

 

Trees are budding as much as three weeks ahead of the historical average

this year from New Jersey to Colorado.

 

“Warmer than historical average conditions in the mid-Atlantic and Northeast

will make for a much quicker and more forceful start to the pollen season,”

said Reppert.

Metro areas, including New York City, Philadelphia, Washington D.C., Kansas

City, and Denver, will see pollen arrive earlier and climb to higher levels

compared to recent seasons.

Tree pollen may not be as intense across the Southeast, but Reppert warns

that the season could last longer than recent years.

 

Grass Pollen

 

The primary allergy concern will shift to grass pollen as spring transitions to

summer.

 

An “intense and prolonged” grass pollen season is forecast for the interior

Northeast and Midwest. Some areas of the Pacific Northwest could also

experience elevated grass pollen levels throughout the summer.

 

Peak tree pollen levels in the Pacific Northwest and parts of the Northeast are

expected to occur around Independence Day, when millions of people spend

time outdoors at parades, barbeques and firework displays.

Reppert says a slight downturn in rainfall in July and August along parts of the

Mid-Atlantic could provide a break for allergy sufferers.

 

Grass pollen levels are expected to be near or below historical averages for

most of the Plains, Rocky Mountains and the Southwest.

 

Weed Pollen

 

The most widespread pollen-related issues are likely to occur in more than

two dozen states during the second half of summer.

 

A hyperactive weed pollen season is predicted to occur due to widespread

warmth.

“Moisture will make a rapid surge in weed pollen over the Pacific Northwest

and into the northern Rockies and northern Plains,” said Reppert.

 

Advice For Allergy Sufferers

 

With more than 80 million people in America living with seasonal allergies,

Reppert says it’s important to monitor weather forecasts and talk with your

doctor to help manage symptoms.

  •  

- Start taking allergy medication before issues begin
 

  • - Avoid outdoor activities during the late morning and afternoon hours
     
  • - Keep car and home windows closed
     
  • - Use air conditioning during high pollen days
     
  • - Take off shoes and wipe down pets before going inside
     
  • - Monitor pollen levels on the AccuWeather app
