AliciaC, a shade cover will help keeping the hot sun from scorching the fruit. But the only thing I fear from the high temps over 90's in daytime and 70 at night (as it is here now) is that the high heat will sometimes keep blossoms from setting fruit, and the blossoms just drop off. sometimes spraying the blossoms with epsom salt will help some, (1 tbs to a quart of water). I have never used a shade cover (black mesh) so I couldn't say if it would help or not except from scorching the fruit.
good luck and keep us inform
