I live in the UK i.e scotland, I need an application or website that can tell me the weather exactly in june,july,august
Who knows! Right now, March, they have snow in the Highlands today!!
We hope that by July and August it should be nice with temperatures in the low to mid 20's (so around low 70s) but that is not guaranteed. You could have a great day followed by torrential rain.
All I know is that you have to watch out for the clegs which are insects that bite and really hurt! Use repellent. almost 8 years ago
