Weather Forecast For London In September

So, I was walking my dog, Alfie, the other day, and we passed this old lady who was knitting away like there's no tomorrow. I struck up a conversation, you know, the usual 'nice day, isn't it?' kind of thing. She looks up at me, squints at the sky, and says, "Mark my words, young man, September's a tricky month in London. You never know what you're gonna get." I chuckled, but her words stuck with me. And here we are, September's knocking on our door, and I thought, let's see what the weather has in store for us this month, shall we?
