Pollen calendar

Is anyone else suffering with hayfever as DH and I are? Something has just started flowering, and from 2 days ago we've both been miserable. I was doing some searching and I found this fascinating calendar which seems to indicate that we're sensitive to lime tree pollen. And according to the cheerful little titbit at the bottom, a glass of beneficial red wine is not going to help. D'oh.

ETA: Very interesting. Both of our noses started behaving in a more civilised fashion around the third week in July. According to this chart, that seems to imply that the problem could be lime trees. We haven't got many limes close by, but there are a lot in the park about a mile and a half to the east of us. We've had more winds from the east than usual this year so maybe, just maybe, we've found our answer.
