Weather forecasts. More than 4 days out they tend to be wrong; within 4 days they constantly predict one form of armageddon or another.

LinkedIn. A series of bots and AI generated sludge broadcasting into the void, for other bots to like and generate further sludge from.

You'll be surprised how accurate they are these days and way beyond four days. Because of that, they're not only useful but vital for any outdoor based endeavour for which an indication of the likely conditions that will prevail are of vital importance.

They may be accurate but they are waaaaaaaaay too detailed these days. On the national tv news, they now have an 'introductory' bit, then the 'detailed' bit, then a summary. Then the local news does similar. All I want to know is whether I need a winter coat, a raincoat, or none of these. Its helpful to know if there's going to be extremes, but FFS Alexa now gives me a 'weather warning' for rain! I switch off mentally before the weather person gets to the salient bit. It's (nearly) all bks.

I used to use Wunderground but it was never right so I changed to Accuweather and they avoid being wrong by changing the forecast as it happens on the fly.

They will say tomorrow will be 10deg and raining in the morning with clouds in the afternoon. when its 5deg in the morning and sunny they change it to suit but keep cloudy for the afternoon and when it rains in the afternoon they change it again.

That's not a forecast, thats just looking out the window.

Daily reports of stock market performance or the pound against the dollar or euro. Daily variations are neither here nor there and of no use to anyone. It’s longer-term fluctuations or trends that count.

The thing with the weather forecast in the UK is that you can have 3-seasons thrown at you all in the same day. So, if you're looking for information about whether you need a warm coat or not on a particular day, then the answer is likely yes. And an umbrella. And probably nothing more than a T-shirt.


Anyway, my contribution... what is the point of politicians. If we had none, the world would revolve just fine with the laws already in place. But no, we're subjected to this group of tossers whose only remit is to change whatever is in place, only for the next lot of tossers to change it again. Our tax laws - for example - are just ridiculous... the longest in the world at 21,000 pages. Why? Really, why?

Ecmwf does 10 day forecasts. Thr accuracy of the models is usually above 90%.

Occasionally they get it eerily right. One time I was camping with a beast of a tent. It predicted rain at 5am on the day I was leaving. I ignored it and it arrived on the minute so had double the weight to contend with on leaving.

Rest of the time when I've really needed them, usually flying to weather sensitive locations, they've been useless far more often than not.

Careful with that one, you're choosing 'Women things' you switch that to silly money Watches and Cars that'll never leave their air conditioned garages and you'll be in trouble!

I think I posted pretty much the same thing in the "Things that annoy you" thread the other week.

In their mission to be the most accurate the weather apps are constantly changing the forecast to the point that they're mirroring what is happening now. So yes, you might as well just look out the window. I still don't understand how the rain percentages work though. How can it be a 75% chance of rain during the day when the forecast for the hour says 100%?

I'm not sure if this is accurate or not, but the way I look at is, the weather report is telling you that someone is throwing a ball at you, and giving you odds of it hitting you.

I live on the top of a hill so I can see the balls land, and the weather forecasts are eerily, spookily accurate these days. Even if the ball doesn't hit me personally

I do get that. However when they say that between 10am and 11am there is a 100% chance of those balls hitting me, why does the day forecast say it's only a 75% chance that I get hit? Surely it has to be 100% for the day as well as I'm definitely going to get hit between 10am and 11am.

BBC weather is reasonably accurate over a short period of a few days. Upto minute stuff is best seen from met office weather radar, tracking the rain etc

Don't forget that TV serves a great many people, not just you.

You may consider the content to be overly complicated - others will appreciate the detail.

Also seen with metoffice temperatures. eg daily min/max = 1C/10C but you look at all the hourlies and there's nothing that low or high.

As a gardener I do tend to pay more attention to the weather forecast than most, and on the whole I would say they are largely accurate but as I use two different weather prediction platforms sometimes they can say totally different things for the same hour of the same day, which is always a bit odd.

I think the forecasts have tended to be careful of not repeating the Michael Fish storm issue a few years ago.
I am outdoors a lot so look at them and decide on what is likely. Some areas have " micro climates" due to topography and I use my local knowledge to assess the local weather based on past experience.

Why do we need a dedicated human on TV to tell us about the upcoming weather - a few screenshots and we are fine...
