Do April Showers Really Bring May Flowers?

The phrase, “April showers bring May flowers “ has been around for centuries. It is derived from a poem called A Hundred Good Points of Husbandry, written in 1557 by Thomas Tusser, an English poet and farmer. This old adage, however, does not necessarily hold true in the northeastern United States.

Coming on the heels of the snowy months of winter, April typically produces more rain than snow. Many people, therefore, consider it a rainy month. Since water is necessary for the overall survival of plants, they also associate it with the bloom of flowers in May. Nevertheless, according to botanists, perennials – the plants that go dormant in winter and re-grow in the spring – are more dependent on the soil moisture derived from winter snowmelt and the long-term local precipitation pattern.

In the end, though, temperature is the most significant factor in determining when a flower will bloom. As soon as the weather becomes more spring-like, flowers will start to blossom, regardless of how much it rained in April or whatever the prior month was. That said, a “false spring” – a warm spell that triggers flowering but is followed by a hard frost – can kill the fragile blooms.

It is also worth noting that while April is a wet month for many places in the US, it is not always the wettest. Here in New York City, it ranks second. July takes the top spot, because of the downpours associated with its strong summer thunderstorms.

March: In Like a Lion and Out Like a Lamb

“March comes in like a lion, and goes out like a lamb”. This old proverb refers to March’s famously changeable weather.

As a month where we transition from winter to spring, March can often start off cold and blustery, but end warm and calm. From the beginning to the end of the month, the average daily temperature increases by 10°F. Exact conditions, of course, vary from year to year.

Although the precise origins of this popular phrase are unknown, many believe it is based on the constellations. At the beginning of March, Leo (lion) is highest in the midnight sky, while Aries (ram) begins to rise toward the end of the month.

The Folklore Behind Groundhog Day

Today is Groundhog Day, the midpoint of the winter season.

On this day, according to folklore, the weather conditions for the second half of winter can be predicted by the behavior of a prognosticating groundhog. If the groundhog sees its shadow after emerging from its burrow, there will be six more weeks of winter. If it does not see its shadow, then spring will arrive early.

The practice of using animal behavior to predict future weather conditions goes back to ancient times. The particular custom that we are familiar with in the United States grew out of the old world tradition of Candlemas that German settlers brought to Pennsylvania in the 1880s. Today, many communities across the U.S. and Canada continue this age-old ritual with their own special groundhogs.

The most famous of these furry forecasters is Punxsutawney Phil from Pennsylvania. He gained celebrity status after starring in the 1993 film, “Groundhog Day”. Here in New York City, our local weather-groundhog is Charles G. Hogg. A resident of the Staten Island Zoo, he is more popularly known as “Staten Island Chuck”. This year, both groundhogs are calling for an early spring.

But long-range forecasts can be a tricky business, so we will have to wait and see what actually happens. Either way, the spring equinox is 46 days away.

Groundhog Shadow or Not, Spring has Been Trending Earlier

Today is Groundhog Day, the midpoint of the winter season.

On this day, according to folklore, the weather conditions for the second half of winter can be predicted by the behavior of a prognosticating groundhog. If the groundhog sees its shadow after emerging from its burrow, there will be six more weeks of winter. If it does not see its shadow, then spring will arrive early.

But, shadow or no shadow, as the planet warms spring is trending earlier. Below is a look at the temperature trend during the six weeks following Groundhog Day since 1950 in New York City.

What are the Dog Days of Summer?

The “Dog Days” of summer have arrived. This popular saying refers to what are traditionally the hottest and most oppressive days of the season.

Rooted in astronomy, the phrase is linked to Sirius, the brightest star seen from Earth. As part of the constellation Canis Major, it is known as the Dog Star.  During most of July and August, Sirius rises and sets with our Sun. Ancient Greeks and Romans believed it acted like a second Sun, adding extra heat to summer days. Today, we know that light from this distant star does not affect our weather, but the name has endured.

Varying by latitude around the globe, the so-called “Dog Days” of summer typically run from July 3 to August 11 in the United States.

A Look at Rainbows and their Legendary Pots of Gold on this St Patrick’s Day

According to Irish folklore, a pot of gold can be found at the end of a rainbow. In reality, however, it is impossible to locate the terminus of this optical phenomenon.

For a rainbow to form, rain has to be falling in one part of the sky while the sun is out in another. The water droplets in the air act like prisms that refract and reflect the sunlight, revealing the colors of the visible spectrum. Red is refracted the least and is always on the top of the bow while blue is on the bottom. Since we only see one color from each drop, it takes a countless number to produce a rainbow.

That said, these colorful arcs are not physical entities that can be approached. No matter how close they appear to be, they are always tantalizingly out of reach. Nevertheless, most people consider seeing one to be a treasure with no gold required.

With a little luck, you can spot a rainbow if you face a moisture source – rain or mist from a waterfall – while the sun is at your back.

Happy Saint Patrick’s Day!

Searching for the End of a Rainbow

At the end of a rainbow, according to Irish folklore, lies a leprechaun’s pot of gold. In reality, however, the true end of a rainbow is impossible to locate.

A rainbow is an optical phenomenon that forms when water droplets in the air both refract and reflect sunlight to reveal the colors of the visible spectrum in an arch formation. It is not a physical entity that can be touched or approached. To see them, the National Center for Atmospheric Research says you need to be both facing the source of moisture and be standing at a 42° angle to the sun’s rays.

This specific line of sight means that no two people will ever see the exact same rainbow. It also means that as you attempt to move closer to the rainbow, the further away it will appear. So, try as you might, you will never get close enough to see a rainbow’s true terminus.

In the end, rainbows are all about perception.  For many people, even without the promise of a pot of gold, the joy of sighting a beautiful rainbow is reward enough.  Happy Saint Patrick’s Day!
