London weather tomorrow and next week

[Kittywampus]

Hi, I'm supposed to be taking the children on a day trip to London tomorrow, including an open top bus ride. But the weather forecast is for showers.

I could put it off for a week and go next Sunday (29th), but that's the only other day we can go. Can anyone tell me whether the weather is likely to be better or worse? Thank you

Tomorrow, the showers are looking more likely in the afternoon for the London area so I guess doing the bus ride in the morning would be better, if you're able to do that.

The 29th is a loooong way into the future when it comes to forecasting but at the moment, the 29th is looking showery as well and not especially warm - 15-18C

It's car free day tomorrow and Open House weekend so there will be stacks to do in town.

Thanks for your replies. I'm still undecided!
