Respuesta :
Looks like temperate in this case means even. She doesn't change as much as the summer weather.
Answer:
Temperate here in the poem would mean "even'.
Explanation:
"Sonnet 18" by William Shakespeare is also commonly known as "Shall I Compare Thee To A Summer's Day? This sonnet of Shakespeare shows the speaker's praise of his beloved.
By comparing his beloved to that of the summer weather, Shakespeare is using imagery to emphasize on the loveliness of the beloved. And when he said that she is more lovely and more temperate than the summer, he is implying that unlike the fluctuating summer weather, she is even in all circumstances. She radiates stability and is unaffected by anything.
