It's still only April and it's pretty common to still have frost during April some years.
A couple of weeks ago people were whinging about all the rain.
In a few weeks time, people will be whinging about it being too hot.
There's no such thing as "wrong weather", it's wrong clothing, wrong activities, etc.
If you want somewhere with steady weather, move abroad, if you want hot, move to the Med, if you want cold, move to Canada. But here in the UK, the entire climate has always been very changeable, sometimes hot years, sometimes cold years, sometimes wet years. That's the nature of our climate.
