If you have seasonal allergies and are traveling to Houston during December, January, May, or September, make sure you have an allergy treatment plan that works for you before your trip. During your trip, check the local pollen count daily to adjust your plans accordingly.

When Does Allergy Season End?

Houston has warmer weather that promotes a longer allergy season. Because of this and the prevalence of cedar fever, Texans rarely get a break from their seasonal allergies. Even if you aren’t allergic to cedar pollen, indoor allergens can still cause issues for many allergy sufferers during the winter.

If you suffer from indoor allergies, such as allergies to dust, pet dander, or mold, you might notice that they worsen during the winter if you spend more time inside than usual.

Allergy Symptom Relief and Treatment

Allergies can feel difficult to manage, but there are several different methods you can try out to decrease or eliminate your allergy symptoms.

Limit Exposure

An effective method of decreasing your symptoms is limiting your exposure to the allergens that are triggering your allergies. While pollen can be difficult to avoid, there are ways that you can decrease your exposure to pollen in Houston.

  • Check daily pollen count: Generally, pollen tends to be highest in the morning and afternoons, making evenings the best time to go outside in Houston. Another tip is to check the Houston pollen forecast and limit outdoor time on high pollen count days.
  • Trim trees, mow the lawn, and pull weeds: Regularly manicuring your yard can reduce the pollen released directly around your home in Houston.
  • Wear a mask outdoors: To prevent pollen from entering your airways, you can wear a dust mask when you go outside in Houston.
  • Clean regularly: Due to the sticky nature of pollen, it is essential to clean your home and do laundry frequently. Similarly, showering after being outdoors will allow you to wash off any pollen.
  • Keep windows closed: Pollen easily enters the home through open windows and doors. Running your A/C and closing windows and doors during allergy season in Houston will effectively combat this.
  • Install a HEPA filter: Installing a HEPA filter on your A/C can help reduce the pollen levels circulating in your home.


Over-the-counter (OTC) medications are widely available in Houston, and they provide short-term relief from your allergy symptoms. If antihistamines, nasal sprays, and eye drops don’t provide enough relief from your seasonal allergies, you can look into allergy treatments that will provide long-term relief instead of just masking your symptoms.

Sublingual Immunotherapy

If you want lifelong relief from your seasonal allergies in Houston, sublingual immunotherapy is the best solution. Sublingual immunotherapy involves exposing your immune system to small doses of the allergens that trigger your allergies. Through this exposure, your body becomes desensitized to your allergies, providing long-term relief.
