I am now in Woking. Picking up bike Monday and heading Northwest. Hoping to miss "thundery showers"
14-21 days ?!
I’d just like them to get the next 24 hrs close enough to be meaningful !!
Oh, that’s alright then. If Professor Liz says so then it must be right.From https://www.bbc.com/news/articles/cwy1epz58pyo.amp
“Liz Bentley, a professor of meteorology at Reading University and chief executive of the Royal Meteorological Society, says that a one-day forecast is correct over 90% of the time.”
While I seem to recall a certain scepticism from you regarding the Beeb, there’s lots of similar references on the net.
The UK is a relatively small area sitting at the conjunction of several weather systems, making life interesting for forecasters. Denmark, being even smaller also has this problem![]()
Read my post above. It’s not the beebs fault. It’s the public’s fault for ‘lacking trust’. Obviously…The UK Met Office is a national joke as is the BBC. You first have to define what accurate is which is missing from the BBC puff piece

If Professor Liz says it’s dry then obviously I’m wrong in thinking that I’m getting wet when riding along in the rain when it’s supposed to be dry.
Actually, that’s an amazing article, and SO Beeb !
The headline is: “Why weather forecasters often appear to get it wrong”
Note the word APPEAR ! Inserted into that sentence to say that they were NOT really wrong… it just APPEARED that way!
And the “there are still gaps in public trust” ! Not that the public is being let down… it’s the public who lack trust !
In my opinion one of the issues is that they try too hard to be too (impossibly) precise. But whatever the reasons, and however you look at it, they are wrong SO often it just ain’t funny.
Try this little exercise: take a screen shot of the 10 day overview on your phone. Do this every day for 10 days. Then look at the pictures you’ve taken and just look at how often it changes for any given day.
You can do the same exercise for a day, take a screenshot of today’s forecast several times throughout the day and see just how much it changes.
This is not a joke: there are 4 of us who ride fairly frequently together, two young uns (I’m one) and 2 old boys. The young uns always check the weather in order to decide go / no-go, or what to wear, etc. the Old boys NEVER check, they just press on with their plans regardless. The amount of times us young’s uns get it wrong is amazing, the Old boys have a far better overall outcome.
This does rather seem to be a case of observer bias - both for the Beeb and the weather apps!Oh, that’s alright then. If Professor Liz says so then it must be right.

Remember, I never claimed it was easy for ‘em… just that they are not reliably accurate.This does rather seem to be a case of observer bias - both for the Beeb and the weather apps!
The very nature of chaotic systems means that the results will change constantly. Small differences in the input result in large changes in the output. Look at several different weather services and if they are using different algorithms and data, the results will differ. Part of the difficulty of weather forecasting is precisely this, which of the results is most probable. My experience has generally been positive, it does depend on one's expectations though.
I learned to use weather forecasts when I was sailing, even back in the 80's the daily forcast was surprisingly accurate. We were not really concerned about whether it was going to drizzle or be dry, more concerned about wind speed and direction.
To decide what gear to use for today's ride, it's better to use the radar pictures to get a more precise idea of the conditions in an hour or two.
