In spring, grass pollen becomes important. It usually rises in May and stays high through June and July. Ryegrass, meadow grass, and other lawn grasses release lots of pollen. Warm, sunny weather can make grass pollen spread farther across Hitchin.
In late summer, weed pollen can be found. It is usually lower than grass pollen, but it still matters in August and September. Plants like nettles and docks release pollen then. Some other wild plants may also add small amounts during this time.
In autumn and winter, pollen levels are usually much lower. Most trees and grasses stop releasing much pollen. A few plants may still shed small amounts on mild days. By November and December, the air in Hitchin often carries very little pollen.
