Hello Gelyn :) I agree with Onte, we should paraphrase this sentence a little: It is not natural to say "today" and "at night/tonight" in the same sentence. So, it would be better to say: The weather is quite good tonight. (Because the word "tonight" already has these two words: "today" and "night/evening". Hope, this helps :) Regards, Anastasiia

The weather tonight is quite pleasant.

The weather today's quite good at night

The weather is quite lovely today.
