The perfect weather (in my opinion) for a wedding is when it is slightly cloudy because it gives the best light for photos. Harsh sun light on a bright sunny day makes it difficult to get flattering photos, you end up with dark shadows and really bright contrasts. Obviously, weddings still look fabulous on a super sunny day, and you can still get amazing shots whatever the weather. Just don't panic if it isn't how you imagined it to be :)
