For many, the arrival of allergy season is a bittersweet time. It's when we see the trees bursting into bloom and hear the lively sounds of nature awakening. But for those who suffer from allergies, this beautiful transformation also brings a less welcome change: a range of pesky allergy symptoms. Knowing when allergy season starts is really important for anyone who finds themselves battling sneezes and sniffles as the weather changes.

What Are Allergies?

Allergies occur when your immune system reacts to a foreign substance — such as pollen, bee venom, pet dander, or a particular food — that shouldn’t cause a reaction in most people. Your body's response can inflame your skin, sinuses, airways, or digestive system. Understanding allergies is key to managing them during their peak seasons.

What Are Common Allergy Symptoms?

During allergy season, many people experience a variety of symptoms. These can range from mild to quite bothersome and include:


  • Sneezing
  • Runny or Stuffy Nose
  • Itchy Eyes
  • Throat Irritation
  • Headaches

Being aware of these symptoms is important in identifying and managing seasonal allergies effectively.

What is Allergy Season?

Allergy season is that time of the year when allergens like pollen are at their peak in the environment. During this time, many people experience heightened allergic symptoms, such as sneezing, itchy eyes, and congestion. The exact timing of allergy season can vary based on your location and the specific allergens you are sensitive to. To learn more, take a look at our other article about the allergy season timeline.

When Does Allergy Season Typically Start?

Generally, allergy season begins in spring, when plants start to bloom and release pollen. However, it can start as early as late winter in some areas, especially with mild winters. The season usually peaks in late spring and early summer, but it can extend into fall with different plants pollinating at different times.

Allergy Season by Location

Yes, the onset of allergy season can vary significantly depending on where you live:

  • In warmer climates: Allergy season can start earlier and last longer.
  • In colder regions: Allergy season might begin later and be shorter.

The types of plants prevalent in your area also play a role in determining the start of the season.

Allergy Seasons for Different Allergens

The allergy season isn't a one-size-fits-all timeframe:

  • Tree Pollen: Typically peaks in spring.
  • Grass Pollen: Often rises in late spring and early summer.
  • Weed Pollen: Commonly becomes problematic in late summer and fall.
  • Mold Spores: Can be an issue in both spring and fall, especially in damp areas.

How Can You Prepare for Allergy Season?

Preparation is key to managing allergies effectively:

  • Monitor pollen forecasts and stay informed about pollen levels in your area.
  • If you take allergy medications, consider starting them before the season kicks in.
  • Regularly clean your home to reduce indoor allergens.
  • Use air purifiers to help remove allergens from your indoor air.
