Sometimes I'll be walking around a supermarket, and a shopper will approach me in the aisle. "I hosted a barbecue on Saturday and you told me it was going to rain," they will say. "And it didn't. Why did you get it wrong?".

Or the opposite: they planned for a day of sunshine, only to be disappointed by grey skies. Or a parent might ask me in March what the weather might be like for their son's wedding - in September.

Those people are always delightfully friendly, and the conversations are part of what makes presenting the weather - which I've been doing for the last three decades - such a joy.

But they also shed light on a strange fact.

Over my career, forecasting has improved almost beyond recognition. We can now predict the weather with much higher accuracy, and in more granular detail, than when I began presenting in the mid 1990s.
