Allergy Seasons

For people with pollen allergies, your symptoms will be at their worst when trees are blooming. In most cases, this means early spring, but it may differ depending on where you are located, and seasons can vary from year to year.

Below are peak blooming/allergy seasons for trees common in and around Texas:

• September, February-March: Fall Elm
• Winter months: Mountain Cedar
• Spring months: Ash, Mulberry, Sycamore, Willow
• March – April: Oak
• April: Pecan

Weed allergies have peak seasons, including:

• August – September: Marsh Elder, Sagebrush
• September – October: Ragweed
• December – January: Red Berry Juniper
• July – November: Pigweed

If you suffer from weed allergies, you may want to avoid being outside between the hours of 10 am and 3 pm, which are considered the worst time of day to be outdoors during peak weed allergy season.

Grass and mold are a year-round problem in Texas.

That said, grass allergies tend to peak in the summer months, with more lawn mowing. Mold allergies peak whenever there’s moisture in the environment, perhaps worsening in the rainy season.
