I'm not sure what time is bad for me, since I was diagnosed in may. I know now that summer is not good for me (I'm not allergic to any grass or stuff, I'm allergic to the smell of them). I've been out of breath for about 2 weeks (heat wave). I'm not good at all with humidity, exercise, perfums, molds, and illness (that's all I know for now), so I'm pretty scared about winter (I'm always sick in the winter). I guess I'll just have to see.
