Weather for Dads

Questions I asked myself while building Weather for Dads, and a few I get asked around the BBQ. Real answers, backed by real rain gauges and the forecasts we mark in public on the accuracy page.

Can you cut wet grass?

You can, but it's best to wait: wet grass tears, clumps and clogs the mower, and soft ground ruts. How long to wait after rain or dew, and how to tell.

Is it BBQ weather? When it's too cold, wet or windy to barbecue

Check your postcode for BBQ weather today. It's on from about 13 degrees if dry and calm, best from 16. Too cold, windy, wet or hot to barbecue?

What temperature is too hot, or too cold, to walk a dog?

There's no official cut-off. In heat, test the pavement with your hand for seven seconds; in cold, small dogs struggle from about 5 degrees. UK vet advice.

Will my washing dry outside today?

Check your postcode: washing dries outside if it stays dry and breezy, as wind beats warmth. Towels, bedding, cloudy days, winter and overnight too.

How far ahead is the weather forecast accurate?

We marked 2.4 million UK forecasts by how far ahead they looked. Temperature holds up for about three days, rain for about one. Beyond that, it's a rough guide.

Which UK weather forecast is most accurate? We checked 2.4 million

Is the Met Office accurate? Is Apple Weather? We marked 2.4 million UK forecasts. Who was best for rain, temperature and wind, and why no one wins all three.

What does 40% chance of rain actually mean?

A 40% chance of rain means rain at your spot on four days in ten like this one. Not 40% of the area, the time or the amount. What 10% to 90% mean in practice.

When to stop mowing the lawn in the UK

Stop mowing when the grass stops growing, usually once days stay below about 6 to 7 degrees. When that is in the UK, how high to leave it, and why not on frost.
