If this is not practical, be suspicious of a meter reading that calls for an exposure much less than 1 stop less than the basic exposure for average, frontlighted subjects in bright or hazy sunlight. If the meter reading is too high because of the bright background, you'll probably get better results using the exposure recommendations given here. Weak, Hazy Sun Weak, hazy sun is flattering lighting for informal portraits. Shadows are softer and it's easier for people to have natural expressions when the sunlight is not so bright for their eyes. The light from the sun is weakened by a heavy haze and the sun's disk is visible but diffusely outlined.
Shadows are weak and soft but readily apparent.
Since there are no harsh shadows, these conditions are wonderful for photographing people. With weak, hazy sun, you use 1 stop more exposure for average subjects than the basic exposure for bright sunlight. The sun is hidden by light clouds. The sky may be completely overcast or there may be scattered clouds. You can't see the sun's disk, but you can tell where it is by a bright area in the sky.
