No Sharks seen in False Bay since April

I saw False Bay in a headline and it peaked my interest - Apparently there is a Great White sighting drought around Cape Town. Probably nice to know when you're in the water, but maybe less of a good sign for the earth overall. 

How common is a sighting on a normal year? (i mean a shark you personally see breach or follow)

Anyways, get in some Miller's runs shark-free while it lasts!

Is it possible there is a presence of Orcas in False Bay? Other than humans Orcas are a known predator of Great Whites. Documented at the Farallon Islands.

Spotted a bronze whaler shark 2.7km due west of Strand Beach yesterday (Sunday 8 Sept 2019).
