A shadow occluded the sun over Bendan and he looked up, squinting.

Thick, greasy, black smoke occluded the sun above, searing hot and merciless.

I bent my mind toward the way away and clouds occluded the sun.

A shadow suddenly fell upon us, as though a cloud had just occluded the sun.

Clouds did pass overhead, occluding the sun, but none released any of their life-sustaining rains here.
