The summer months are a time that most people look forward to as a chance to spend time outdoors.
Hayfever sufferers are likely to see things differently.
The pollen season starts first with trees, then grasses then weeds.
And the further north you live, the later it comes.
In the UK, trees start in February with grasses running through the summer and mould spores can set off hayfever until October.
It all depends on which plant's pollen doesn't agree with you.
