Weathervane Forecasting

Modern weathervanes come in lots of fancy shapes for decorating roofs. Before modern weather reports weathervane forecasting was the main reason for this roof adornment.

Several years ago we worked on the house roof and added a small cupola over the garage and dormers over the main house to improve the looks of the house. The cupola was a perfect place for a weathervane.

The key to weathervane forecasting begins with careful alignment of it to the points of the compass. Next comes careful observation.

The weathervane arrow is pointing south. This usually means warmer weather is blowing in. Warm and cold are relative terms as 60 degrees in August is cold and warm in February.

We didn’t expect much from our weathervane. The house is nestled between three hills with a valley in front of it. The hills shield the house from the wind.

Still it was interesting to note which direction the wind was coming from. Patterns began to emerge.

The expectation was for cold winds to come from the north and warm winds from the south. Most of our big storms come from the west.

Observations showed the winds rarely came from true north or south. This past winter the warmer winds came primarily from southeast and colder winds from the southwest.

Get out the coats. The wind is out of the northwest and has ice in its teeth. The weathervane arrow gives the wind direction. The larger tail catches the wind turning the arrow.

When really cold temperatures started coming in, they came from the west veering to the northwest. Frigid temperatures did pour down from the north.

I’ve gotten into the habit of doing some weathervane forecasting. On days the radio forecast tells a change is coming in, I note the wind direction. When the direction changes, the temperatures change a short time later.

The radio isn’t great for forecasts as they assume most people watch television. We don’t. Weathervane forecasting works for quick notes and to see the trend for the day.

Our April snow came in on a northwest wind. It’s leaving with a southeast wind. My garden, goats, chicks and I are hoping the southeast wind will blow for many more days.
