Narrative:

While climbing to altitude over jump zone; I observed a large cloud moving over the airport. The cloud was at approximately 6;000 feet; and estimated 1 mile by 1/2 mile in diameter. Approximately 500 to 700 feet in depth. As we approached our exit point for the skydivers; I noticed part of the cloud was still over the airport. I advised the jumpers in the aircraft that there was a cloud in the vicinity of the airport and to let me know which way to adjust my flight path in order to ensure cloud clearance. When I was on jump run and turned the exit light on; 5 experienced jumpers exited the aircraft. As the tandem instructors approached the door; they advised me to go around and offset jump run slightly to the west to avoid the cloud. The remaining jumpers exited the airplane.when I landed; I was advised by an observer on the ground that the first 5 jumpers had penetrated the cloud. An announcement was made to the entire drop zone that disregard for cloud clearance requirements would not be tolerated and everyone was warned.
