Hay fever symptoms usually appear when the pollen count, which is a measure of the number of grains of pollen in one cubic metre of air, exceeds 50.

Weather conditions affect how much pollen is released into the air, and on humid and windy days, pollen spreads easily, but on rainy days, pollen can be cleared from the air.

On sunny days, the pollen count is highest in the early evening, and that's when you are most likely to suffer from hay fever symptoms.
