June is an iffy month... sometimes it can be quite consistent, but we are not starting out good here! April and May were pretty good, but we have certainly shut down since Memorial Day.
Ah, I usually see July and August trading off as being the worst months. In August, the frontal systems are really weak, so we have to hope for Tropical Storms. Usually towards the end of the month, tropical activity becomes more active, but September is when the tropics really kick into gear.
