Pollen Seasons

Trees in Central Oklahoma trees begin pollinating from mid-September (mountain cedar from the Arbuckle Mountains) through early May (pecan) and late June (pine). There is a second elm season in the fall (late August to October) due to the introduction of lacebark elms and cedar elms to this area. Each of the common tree species (elm, oak, maple/box elder, pecan/hickory, birch, mulberry, juniper, sycamore, pine, cottonwood/poplar, willow) usually pollinate for only a few weeks but added together the season is quite long.

Grasses

Central Oklahoma has two grass seasons. Cool season grasses (blue, fescue, timothy, rye, orchard, and redtop) can begin as early as late February or March but after a month or two they stop pollinating totally. The warm season grasses (which do not cross-react with cool season grasses) such as Bermuda, Bahia, crabgrass, and Johnson begin when the weather becomes warm and do not always stop until a good hard freeze in November.

Weeds

Some weeds pollinate in late spring or summer (dock and plantain), but most begin in late summer and fall. Ragweed pollination begins based on hours of daylight and almost always begin when the days shorten around the middle of August. However, the weeds often continue to pollinate until there is a hard freeze, often in late November.

Molds

We find molds in Central Oklahoma every day of the year unless there is a very hard freeze and/or the ground is covered with snow.
The Oklahoma Allergy & Asthma Clinic is a certified counting station for pollen and mold. We are associated with the National Allergy Bureau and the AAAAI. You can find our counts on the internet at www.oklahomaallergy.com. We supply the local media (TV stations, newspaper and radio) with our counts every day they are done. To learn more about the National Allergy Bureau (NAB) you can go to www.aaaai.org.

Ragweed Season is HERE

Ragweed Season

Ragweed Plants Packed with Pollen

Summer fun can turn to fall misery for millions of people who suffer from seasonal allergic rhinitis (hay fever). Sneezing, stuffy or runny nose, itchy eyes, nose and throat, or worsening of asthma symptoms are common in people with undiagnosed or poorly managed hay fever.

The primary culprit of fall allergies is ragweed pollen. A ragweed plant only lives one season, but it packs a powerful punch. A single plant can produce up to 1 billion pollen grains. These grains are very light weight and float easily through the air.

Fall allergy symptoms used to start in mid-August and run through September. In many parts of the country these symptoms now begin in early August and extend through October. Some studies suggest that rising temperatures and higher carbon dioxide levels contribute to longer growth time of allergen-producing plants. In 2023, OAAC reported high ragweed counts beginning in the third week of August. In fact, on August 28, 2023, we had our first ragweed allergy alert day.

Allergies occur when the body’s immune system treats the allergen, in this case ragweed, as a foreign invader. This starts a chemical reaction which produces and sends histamine throughout the blood stream. These chemicals cause allergy symptoms to develop.

Controlling symptoms
Proper diagnosis is the first step in managing your symptoms. An allergist will give a physical exam, ask about your health history and perform allergy testing to determine exactly what you are and are not allergic to.

Although there is no cure, ragweed allergy can be managed to improve the quality of your life.

The best control is to avoid contact with the pollen. This can be difficult, but resources are available. The National Allergy BureauTM (NAB) tracks pollen counts regionally to help you plan when you should avoid spending a lot of time outdoors. Remember to follow the OAAC on social media for the OKC area. Our counts are collected from the top of our main office building Monday-Friday by our certified pollen counters.

Talk to your doctor about medications that may provide temporary relief from symptoms. Your allergist/immunologist may also recommend immunotherapy (allergy shots) or sublingual immunotherapy (SLIT) allergy tablets, treatment. This long-term treatment approach can significantly reduce the frequency and severity of symptoms caused by allergic rhinitis.

Did you know?

  • The tall goldenrod species of ragweed gets blamed for most of the pollen, but a primary cause of allergy symptoms is the tooth-leaved ragweed that lives low in the grass.
    • Ragweed can be found in almost all states in the United States as well as in Canada.
    • An accurate diagnosis is essential for managing symptoms. Allergy testing performed by an allergist can determine what you are and not allergic to.To the point
    Although often associated with hay fever, ragweed can also cause skin conditions such as allergic contact dermatitis and hives.
