Different allergens: Every person's allergies are triggered by specific allergens. When that allergen reaches high enough concentration then the allergies are triggered.

Depends: Seasonal allergies occur at different times of the year as different pollens come out. In the spring it is tree and grass season. In the fall it is ragweed season. At least in the mid atlantic area.
