Sun:

"the day, already bright with sun, hit me like a slap in the face." (47)
- Meursault, (here) sees the sun as blinding. Uncomfortable for him.

"we stood there motionless in the sun" (54)
- The sun is the strongest thing. They could be doing much more but the only noticeable thing is the sun.

"the sun was overpowering." & "The whole time there was nothing but the sun and silence" (55)
- Both of these show that the sun is very powerful over the day. It is the most noticeable thing, very strong, and it is "overpowering".

"throbbing in the sun" (58)
- Again, the sun is uncomfortable.
