We are in May. Who would want to go out and use this type of place. Standing outside with rain lashing down, thunder and 50mph winds trying to talk to people whilst your coffee or food gets flooded with rain.
Like the local council growing up. Looking at things with the idea we have Summer weather, or weather that is conducive to being outdoors all year round is not realistic.
I think it is a waste of time trying to force out side areas into a scheme that people won’t use because it is pissing down with rain and freezing cold. It just ends up unused and a hang out for vandals and graffiti artists.
While I agree you raise a fair point... is this really as much of an issue as it used to be? And should it continue to be as much of an issue as it always been? I live in Scotland so I am well used to 'summer' being a week in early April and a week in late September.
But for the last year now the only way to have a family day out, date, exercise, or socialise has been walking in the cold windy rain or sitting in the cold windy rain. I think the majority of people are totally used to it?
Why don't we just accept that we are a cold windy country and embrace it? And create outside spaces that are still enjoyable when it's cold and wet and windy? In my post I said primarily outdoors but I didn't say completely exposed to the elements and unsheltered. 
The two local nurseries - one is a forest nursery and they are outside all day every day, the other have a building but they are outside at least 50% of the time.
The local school - half a day of outdoor learning at least twice per week come rain or shine. If the weather isn't absolutely horrendous they try to be outside more.
I'm all for this. I remember turning up to school when it was raining and there were cars literally backed up the street because some people cannot bear the thought of their little darlings (or them) walking for literally 90 seconds in the rain. We need to accept and prepare and dress and build society around the fact that it rains, without everything having to be inside.
Having said all that, I wish clothes shops would take everything in your post into account 100%. It's insane that the shops are full of shorts and skirts and beach dresses (especially in the north of the country) when it's 9'c in May and pissing with rain, and the only time we'd actually need them is a rare weekend or a holiday abroad.
