Local Environmental Conditions
The landscape around this site in Village of Old Westbury is heavily wooded. With running water close by, riverside vegetation contributes to the local mix. Oak and maple are among the allergenic trees nearby. Beyond the trees, grasses matter a great deal, and mugwort is the main weed source. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Oak and maple lead the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Later, mugwort keeps weed pollen in the air from midsummer into early fall. By late fall, pollen levels are low again.
