What Are Pollen Levels?

Pollen levels measure how many microscopic pollen particles are present
in the air. These particles come from plants such as trees, grasses,
and weeds. When pollen counts rise, people with seasonal allergies may
experience symptoms including sneezing, itchy eyes, congestion, or
asthma flare-ups.

Our pollen forecast combines air quality data and weather modeling to
estimate daily pollen levels across the United States.

Pollen Level Scale

  • Low (0) – Little to no pollen in the air. Most people experience no symptoms.
  • Moderate (1) – Some pollen present. Sensitive individuals may notice mild symptoms.
  • High (2) – Many allergy sufferers may experience symptoms.
  • Very High (3) – Strong allergic reactions are possible for many people.
  • Extreme (4) – Severe pollen conditions. Outdoor exposure should be minimized.

How Pollen Affects Schools

High pollen levels can affect students who suffer from allergies or
asthma. During peak pollen days, schools may consider adjusting outdoor
activities such as recess, sports practices, or field trips.

Parents may also want to take precautions when pollen levels are high,
including:

  • Providing allergy medication before school
  • Encouraging children to wash hands and face after outdoor play
  • Keeping windows closed during high pollen days
  • Using air filters at home

When Is Pollen Season in the United States?

Different types of pollen dominate at different times of the year:

Tree Pollen

Tree pollen is most common in early spring. Trees such as oak, birch,
maple, and cedar release pollen into the air as temperatures rise.

Grass Pollen

Grass pollen peaks in late spring and early summer. It is one of the
most common causes of seasonal allergies in North America.

Weed Pollen

Weed pollen, especially ragweed, becomes dominant in late summer and
fall and can cause severe allergy symptoms.

Why Pollen Forecasts Matter

Monitoring pollen levels helps people with allergies plan their day.
Checking the pollen forecast before outdoor activities can reduce
symptoms and improve overall health.

Our tool provides real-time pollen forecasts using data from
meteorological models and air quality monitoring systems.

Frequently Asked Questions

How accurate are pollen forecasts?

Pollen forecasts use weather models and atmospheric data to estimate
pollen concentrations. While they are not exact measurements, they
provide a reliable indication of whether pollen levels are low or high.

What time of day is pollen highest?

Pollen levels are often highest in the morning and early afternoon,
especially on warm, dry, and windy days.

Does rain reduce pollen levels?

Yes. Rain can temporarily wash pollen out of the air, lowering pollen
counts for several hours.

Which states have the worst pollen seasons?

States in the southeastern United States, such as Georgia, Texas,
and the Carolinas, often experience intense pollen seasons due to
large tree populations and warm climates.
