How To Use the Pollen & Mold Tracker

Our Charlotte pollen count tracker is aimed at helping you manage your seasonal allergy symptoms, whether from pollen or mold. Here are the best ways you can use our tracker to stay in control of your allergies.


At-a-Glance Pollen Levels

You can get at-a-glance pollen levels for top allergens of the day, such as tree, grass, weed, and mold counts. When the icon turns orange or red, it means levels are high and you should take precautions to avoid exposure.

Understanding Charlotte Pollen & Mold Count Levels

If you have a pollen allergy, you’ll want to keep in mind that pollen counts differ across plants. For example, if you have a weed or tree allergy, a count over 50 is considered high. For grasses, a pollen count over 20 is considered high.


For a full reference of what’s considered low, moderate or high for allergy levels in Charlotte, check out the ranges below:


Weeds & Trees

  • 1 to 9 is a low pollen count.
  • 10 to 49 is a moderate pollen count.
  • 50 to 499 is a high pollen count.

Pollen Counter FAQs

What are pollen and mold counts?

Pollen and mold counts measure how much of an allergen is currently in the air. Typically these counts are performed over the course of 24 hours and measure the number of pollen grains per cubic meter.

What are the average pollen and mold counts for Charlotte?

As you approach the high season for your allergies, be sure to keep an eye on our Charlotte pollen counter. By knowing the forecast for your allergies, you can better protect yourself from exposure.

How are pollen and mold counts measured?

To measure pollen and mold counts, researchers make use of air sampling equipment that collects spores throughout 24 hours. After collection, they examine the samples under a microscope to identify the number and type of spores present. From this data, they then calculate grains per cubic meter and give an overall pollen and mold count for that day. Typically, these counts are then translated as low, moderate or high allergy levels so that the public can easily understand them.

What time of year do allergens appear?

Every allergen has a different high season. Charlotte pollen allergy seasons can last from May to July and from August to November. Here’s a good overview of when you can expect the most intense allergy symptoms:

  • Tree: March-June, but most intense in April.
  • Grass: April-September, but most intense in May-August.
  • Weed: August-December, but most intense in September.
  • Mold: July-October, but can be year-round if exposed to spores indoors.

To get more specific allergy levels for Charlotte, be sure to go to our pollen tracker and find out if you need to take precautions to avoid exposure.

What allergens are high in Charlotte?

Ragweed allergies are the most common type, leading to intense symptoms in September. Because ragweed pollen can travel up to 400 miles and some parts of North Carolina are more rural, you may face exposure to pollen even in a city like Charlotte. Charlotte also marks high grass and tree pollen counts. It’s typical to find pollen-producing grasses such as Rye, Johnson, Bahia, and Bermuda, plus trees such as Mulberry, Alder, Ash, and Birch in North Carolina. These plants may result in high allergen counts depending on the time of year.

Why can’t you track pollen on rainy days?

Pollen can’t be tracked on rainy days because of the atmospheric conditions. Essentially, rain washes away pollen so it’s no longer present in the air. This makes it difficult to measure the pollen count accurately. For this reason, pollen counts are typically lower on rainy days. However, there are some conditions that could increase pollen count. For example, humidity and high winds favor pollen grains bursting open and spreading through the air.

Is pollen worse in the morning or evening?

Allergy levels are usually highest when plants are releasing pollen: early in the morning until around midday. In the afternoon, pollen counts tend to drop steadily. While pollen count is typically low in the evening, some people experience nighttime allergies. That’s because you may become exposed as the air cools and pollen falls onto surfaces. You might also be more exposed to pollen because it has collected on your clothes, bedding, or home during the day.

What causes pollen levels to rise?

Pollen levels are highest when plants are able to release pollen into the air. The ideal conditions for high pollen levels include:
  • Season: The time of year when plants release pollen.
  • Weather: Warm temperatures, humidity and winds can boost pollen in the air.
  • Time of day: Plants release more pollen in the early morning.
Depending on the specific plant, these conditions can lead to the typical high season for pollen-related allergies. As you manage your allergy symptoms, you will want to look up the Charlotte pollen count for your specific allergen. For example, if you have a Mulberry allergy, the typical season is March-April.
