Pollen could boom after rain

With rain falling you would be right to think that pollen levels are falling, but once the rain clears we may see a boom.

No matter the time of year, rainfall will dampen pollen easing the amount in the air. While levels will generally be lower, raindrops can kick up grass and weed pollen just not to a significant amount.

Despite this, thunderstorms can also result in greater pollen density due to the humidity that accompanies them causing grains to burst.

Winds then lift the released pollen and carry it far away. As warmer and drier conditions return, grains and grass which have swelled over the past few weeks will begin to release their pollen.

We'll say gesundheit now to get ahead of your incoming pollen sneezing.
