No one has posted under this topic in a while, so I’ll give it a shot. I have compiled a list of around 400 weather folklore sayings and post one each day on my website. More than a dozen on the list predict the weather ahead based on what the weather is in a specific month. No doubt there are others I haven’t come across yet. These two are familiar to all:
If March comes in like a lamb, it goes out like a lion;
if it comes in like a lion, it goes out like a lamb.
April showers bring May flowers.
A number of the month-based sayings pertain specifically to farming:
If February brings drifts of snow, there will be good summer crops to hoe.
When March blows its horn, your barn will be filled with hay and corn.
Still others assure us of the weather ahead:
If ant hills are high in July, winter will be snowy.
If a cold August follows a hot July, it foretells a winter hard and dry.
Fog in January brings a wet spring.
Fogs in February means frosts in May.
When March has April weather, April will have March weather.
If it rains on Easter Sunday, it will rain every Sunday for 7 weeks.
Ice in November to walk a duck, the winter will be all rain and muck.
In 2020-2021, this one was right on target for us here in central Minnesota:
When it is hottest in June, it will be the coldest in the corresponding days of the next February.
(Fact: The hottest 2 days in our area in 2020 were June 7-8; the coldest days in 2021: Feb. 7-8.)
If we have a thunderstorm this coming September, I plan to observe whether there is anything to this saying:
The first snow comes six weeks after the last thunderstorm in September.
We’ll see. In any case, weather folklore adds a pleasing, down-to-earth sidelight to our tech-centered hobby.
