For three minutes, Big Ben will toll from within London's famous Clock Tower as seven years of waiting gives way to a late-night celebration of all things British, and there may be very little rain to fall on this almighty parade.
After several days of blazing hot sun and temperatures reaching the high twenties, Londoners woke up on the morning of the Olympic Games' opening ceremony to 17 degrees and 84 per cent humidity. Here's hoping James Bond's suit is fashioned from one of those clever cooling fabrics.
