Today's pollen count and levels in Atlanta, GA are significant, reflecting the seasonal changes typical of mid-September. As the region transitions from summer to fall, pollen levels can be influenced by various environmental factors.

According to the latest data, the pollen count for today, September 18, 2024, is expected to be moderately high. Residents can expect an average pollen count of around 73 grains per cubic meter of air. This level is primarily driven by ragweed and other late-summer to early-fall weeds which are currently in peak pollination.

Grass pollen is relatively low today, contributing minimally to the overall count. Tree pollen is also on the lower side as most trees have completed their pollination cycles earlier in the year. However, mold spores, which thrive in warm, humid conditions, are moderately high today due to the recent weather patterns, adding to the discomfort for those with mold allergies.

Meteorological conditions such as temperature, humidity, and wind play critical roles in pollen dispersion. Today's weather in Atlanta is expected to be partly cloudy with a high of 82°F and moderate humidity levels. While there is no significant rainfall forecasted for today, which would typically help in reducing pollen levels, the gentle breezes may facilitate the widespread distribution of pollen grains.

Individuals especially sensitive to ragweed and mold spores are advised to take necessary precautions. Closing windows, using air purifiers, and minimizing outdoor activities during peak pollen hours—typically between 10 AM and 4 PM—can help manage symptoms. Over-the-counter antihistamines and nasal sprays may also provide relief.

In summary, today's pollen levels in Atlanta, GA are influenced primarily by ragweed pollen and mold spores, with overall moderately high counts. Residents are encouraged to stay informed and take appropriate measures to mitigate allergy symptoms.
