No, it is absolutely impossible to predict.
You can look at the road conditions on this site:
I have driven this route in March and had appalling conditions, almost total whiteout in a blizzard. We traveled very slowly, the back seat passengers watching the side of the road and front passenger helping the driver. The Icelandic drivers were very good with everyone driving at a slow speed. The road was covered in blowing snow.
Another time in March perfect blue sky and no wind. Mostly i am sure you will have mo problems. So no one can predict what it will be like.
Thank you. Is this highway or ?
Thank you. I was afraid of this!
Thank you! Did you see the northern lights?
