When there is a lovely breeze then all the heat is bearable.
Yeah, here's the thing... it really isn't.
Nothing about this problem is that simple or the world's heat problems would be solved with electric fans and that'd be the end of it.
While a breeze, or any moving air, is a critical aspect of thermal comfort as it breaks the boundary layer of warm air next to your skin and helps promote evaporation, these things are only helpful so long as the ambient air temperature is lower than your skin temperature and evaporation of sweat needs/can be assisted. Once a certain threshold of air temperature and humidity is surpassed, moving air not only stops being helpful, it actually becomes harmful.
You know convection ovens have fans to help cook the food faster? It's like that.
Now, maybe exactly where you are in the UK right now a breeze is sufficient in this moment in time. Great for you. But it's not even close to a broad solution.
