The answer to the question "what allergy season is it?" depends on the location and specific allergens involved. In general, spring and fall tend to be the peak seasons for allergies in many regions of the United States. However, seasonal allergies can occur during a specific time of the year, usually during spring, summer, or fall when certain plants pollinate. The following are some common allergens and the months when they are most prevalent:

• Tree pollen: March through May
• Grass pollen: Late spring and early summer
• Weed pollen: Late summer and early fall

It is important to note that the timing and severity of allergies can vary by location and specific allergens. Mild winter temperatures can cause plants to pollinate early, and a warm, wet spring can lead to high levels of pollen, resulting in a bad allergy season. If you are experiencing allergy symptoms, it is best to see an allergist to determine the cause and receive appropriate treatment.
