Pollen and the related seasons

Pollen is the male fertilising agent of flowering trees, grasses and weeds and is a major allergen that can result in symptoms of seasonal allergic rhinitis (hay fever) for some people. For those affected, different people react to different types of pollen and at differing levels, from mild irritation to a severe deterioration in those people's well-being. Therefore, an understanding of the level and types of pollen in your area can help those affected by pollen allergies to plan how they manage and cope with any symptoms and affects.

Most of the pollens that cause allergic reactions come from trees, grasses and weeds, each with different pollen seasons, and durations. Pollen seasons can start early in spring and can go on into the autumn months. The commencement of the seasons depends upon when the plant begins to go through the flowering process and can be measured by the level of airborne grains concentration per category and species.

The following chart gives the approximate pollen seasons for different trees, grasses and weeds, showing average peak periods. The timings and durations may vary locally, but this general understanding may help those people affected by pollen allergies to plan for the seasonal pollen types that effect them the most.
