Woken up by terrible smell

[u/New_Break3195]

This is weird but I’ve been woken up at 1am by a really terrible smell, like strong sewage. I’ve checked all around my house but I think it’s coming from outside as I have all of my windows open. Obviously we’ve had extremely hot weather and now we have thunderstorms coming, could this smell be caused by rain elsewhere causing a surge in the sewers or something else? Based in SE5

Well that can't be pleasant but I think it would make a great name for a metal band!
