The summary for today says light rain and there's a raindrop image. But none of the individual hourly images has a raindrop and the highest risk of rain seems to be 8% around 10ish.

Surely the summary should be related to what's going on during the day.

I shall have to stick to my tried and tested method of just looking out of the window!

What is an 8% risk of rain anyway?

How much rain is rather important.

Risk has two components, probability and impact.

Knowing one without the other is worthless.

This is how I roll:

If the forecast is bad, it could be good or bad .
If the forecast is good, it could be bad or good.

I can't ever book holidays based on how the forecast is.

Allow me to translate.

It will be simultaneously sunny, cloudy, and light rainy. There's a 3% chance it will be 18°C, and 3 big wet bits will spurt from the North West. I always pay close attention to what that Betty Mountain says.

I tend to use the forecast for temperatures mostly... i like to know if I'm likely to come across ice on tomorrow morning's commute.

regarding rain... if it says it will rain, it usually does. If it 'might' rain, it tends to drop on the hills a few miles east rather than here.

Wind dictates which direction I'll ride. I only head up the Lune valley if the prevailing wind is very light, or if the wind's coming from the east. If it's windy, I like to have it on my back on the last half of a ride.

I don't know if all the probabilities of it raining in any given hour are independent. An 8% chance of rain is a 92% chance that it'll stay dry. Multiply all those percentages up for the whole day, and I make it something like a 40% chance of staying dry all day. So more likely than not it'll rain, at some point. I think the rain symbol is justified.

I don't like or trust it either. Its been (and still is) telling me that every day is 'and breezy', when it certainly hasn't been, until today.

I just go with whatever Lucy Verasemy says......she is in love with me (although she may not realise it just yet) and she is a £millionaire.

Yowindow ........if you have a smartphone, is a nifty little weather app
If you dont mind an ad strip at the bottom it free.
You can buy it for a couple of quid though with no ads.

It has pics and sound and it's interactive. Quite accurate too.
