No, it isn't, I'm afraid. We use 'unclear' to mean that something is difficult to understand, for example, 'It's unclear what you are trying to say'.
For the day, you could say:
Cloudy
Overcast
Dull

I generally don't hear anyone call it an "unclear day". I would use "cloudy day" if the sky is cloudy or "foggy day" if there is a lot of fog.
Also the sentence should be written "On a cloudy day in June, I was waiting for someone" or (for more clarity) "I was waiting for someone on a cloudy day in June"
Hope this helped :)
