How is pollen count measured and how does temperature affect the rate of it in the Spring?

I noticed yesterday evening , I sneezed more than I have in a long time due to , I am guessing pollen, but the thing is I dont see any blooms out yet from anything!





So was wondering if this is pollen or not and btw, the temperature did rise to very warm readings yesterday, so how much would that affect the pollen being given off?





Thanks for your answers!

Pollen count is based upon the number of pollen particles in a litre of air. When the sun shines, pollen gets released into the air, especially from flowering grasses. Since we've had a very mild winter (hope you're not under snow as you read this) there are autumn flowering plants that have been going all winter and spring flowering plants that have got up early.





Another problem with warm weather is that things like dust mites get more active and these also cause allergic reactions.
