Sounds like the winter weather we had in Cape Town Its freezing in winter and central heating is not a thing!!
As for summer in the UK - we have not had one this year yet and we are at the end of August already! We followed Melbourne's weather and it has been better in your winter than our 'summer'! Don't get me wrong, I've had some of the best summers here. But sadly this year was a dud We have spent so much time indoors since the Covid outbreak here last year, combined with home schooling and lockdowns and now a rubbish summer it really is the icing on the cake!
On another note: Im sure through my kids school we will meet and make friends but what, in your opinion, is the best way of meeting people there?
