We were married in June but at the WP and not EPCOT. So here's just my take on the weather - it's definitely hot outside! But as mentioned above, the EPCOT ceremonies are early in the morning which is a huge plus. Also, Florida showers are common in June (it rained during our afternoon ceremony) but since the wedding would be in the morning, that's just another plus! It was hot as we walked around for photos, but that was again later in the day.
