Weather Folklores Do they work?

‘Red sky at night, shepherd’s delight, red sky in the morning shepherd's warning’ True or false?

True Why is the sky red at sunset or sunrise? The atmospheric gases scatter visible light from the sun. Blue light (short wavelengths) is scattered more than red light Low sun = long path through the atmosphere. Most of the blue light is scattered right out of the beam – leaving just the red end of the spectrum

Red sky at night Red sky in the morning EAST Frontal cloud EAST Cloud moving to the east Red sky at night Low sun Frontal cloud Low sun EAST Cloud moving to the east Red sky in the morning

‘When swallows fly high, it will be dry’ True or false?

True Why do swallows fly at a particular altitude? | They’re catching insects to eat Why do the insects fly at that altitude? They have little choice – air motions in the atmosphere carry them around On days with strong heating of the surface, thermals will rise, carrying the insects upwards So on sunny summer days, the swallows will fly high

True or false? ‘When the wind is blowing in the North No fisherman should set forth, When the wind is blowing in the East, 'Tis not fit for man nor beast, When the wind is blowing in the South It brings the food over the fish's mouth, When the wind is blowing in the West, That is when the fishing's best!’ True or false?

True With an approaching easterly weather system easterly winds increase- winds can be warm, dry and dusty in the summer and very cold in the winter Northerly winds are usually cold and gusty and it is often unsafe for boats to go out in this weather Southerly winds provide warm weather which provides pleasant sailing conditions, but is not necessarily best for the fish. Westerly winds usually persist for some length of time, are of relatively constant strength and the weather should be cool and clear. Good for fishing!

‘Rain before seven, clear by eleven’ True or false?

False Late night rain and early morning rain may be the last precipitation of a front passing by. Weather fronts pass just as much in the day as they do at night, so rain in the morning is no predictor of a dry afternoon.

True or false? ‘Seagull, seagull sit on the sand, It’s never good weather when you’re on land’ True or false?

True Seagulls usually sleep on water, but in gusty conditions the water is too choppy. The seagulls then tend to move inland. Therefore…seagulls huddled on the ground are an indicator that the weather out at sea is poor.

True or false? ‘When March blows it’s horn, Your barn will be filled with grain and corn’ True or false?

False ‘Blows it’s horn’ refers to the occurrence of thunderstorms. Thunderstorms in March indicate it is unusually warm for that time of year BUT it is no indicator of a long term weather trend. Farmers rarely plant their annual crop until May.

‘When halo rings around the moon or sun, rain is approaching on the run’ True or false?

True Halos around the moon or sun are caused by refraction of light by ice crystals at high altitude. This high-level moisture is a precursor to moisture moving in at increasingly lower levels, and is a good indicator that an active weather system is on its way.

‘St Swithin's Day if it do rain, for 40 days it will remain ‘St Swithin's Day if it do rain, for 40 days it will remain. St Swithin's Day if it be fair, for 40 days will rain no more ’ True or false?

False! The Met Office tested this myth on July 15th on 55 occasions and on each time 40 days of similar weather did not follow.

‘When March come in like a lion it goes out like a lamb, when it comes in like a lamb it goes out like a lion’ True or false?

False! March can be a varied month for weather and just because it comes in strongly at the beginning of the month doesn’t mean it will finish any more gently!

True or false? ‘No weather is ill, if the wind be still’

True! Calm conditions, indicate the dominance of a high pressure area especially if there are clear skies. High pressure systems tend to give dry conditions but there can be a large amount of low cloud.

True or false? ‘A cow with its tail to the West makes the weather best, A cow with its tail to the East makes the weather least ‘

True! Cows prefer to stand with their back to the wind so it doesn’t blow in their faces. As westerly winds commonly mean calm weather is arriving/continuing and easterly winds usually indicate arriving/continuing unsettled weather this can be a good indication of weather for the next few hours at least.
