It's a very rare sight to spot a whale shark. However, my brother who works in one of the far offshore platforms told me that they regularly see whale sharks as well as tiger sharks by around March until June (some migratory pattern probably?!?).

I have only seen one whale shark out of around 400+ dives in Qatar whereas we have seen many other shark species other than whale sharks (Bull sharks and blacktips most common and very rarely tiger sharks).

@ qtrliving; by the way, Im very good friend with the guy from Wakra you are talking about.
