AUGUSTA, Ga. (WRDW/WAGT) - It is that time of year when flowers are blooming and trees are growing leaves again. Unfortunately, that means pollen is here.

Pine trees are why everything outside has turned yellow, but pine trees usually do not cause allergy problems. Oaks, elms, junipers, and other trees that produce less visible and smaller pollen particles are to blame. The average pollen particle diameter is smaller than the width of your hair. Trees usually pollinate in the morning, so tree pollen is highest between 5-9 am.

Tree pollen counts are expected to be high this week, and grass pollen is rising as the spring solstice is right around the corner.

Weather plays a major factor in the local pollen count. When we have dry, warm, and windy conditions the pollen count is higher during the spring. When we have more humid or rainy conditions the pollen count goes down.

The good news is we tend to see our fair share of showers during the spring season which can help alleviate some allergies.

The best way to battle pollen allergies is staying inside and closing your windows. Pollen does accumulate on hair and clothes, so if you have severe allergies it may be best to change clothes once you get home and also shower. When you do go outside, wear a painter’s mask to prevent particles from entering your airways.
