Local SDT Weather Data! OCT 1 – SEP 30 Water Year


One year of weather data doesn’t allow for trend analysis--but for geeks like me, it is fun. A few obvious things stand out--like when the sunshine is at its peak. Locals always complain about February and it was “brutto” this year rain-wise. November had more rain, but was warmer. Our annual precipitation (47 in.) here is not unlike the situation in Portland, Oregon.  At our farm in central Oregon, we had only 12 in. per year.

The weather in surrounding towns on the Riviera dei Cedri is very similar to Santa Domenica Talao. In the hottest months, SDT can be 1-3 degrees Celsius lower due to hilltown breezes.  BUT, if the breezes are not here, we are usually the same as the lowlanders by the beach.  Average wind in SDT is about 4mph--(see the gust reports for how the squalls behave when they arrive). We had lots of dead air in August. The Calabrians always complain about weather, so I felt right at home. Next week it’ll drop to 17 or so and they will be out in their sausage coats!

Our instruments are from Oregon Scientific. The equipment on the roof has minimal interference from nearby structures.  Like professional weather services, the temps are recorded in the shade. You hear people talking about temps in the high 30’s and 40’s here, but that is in the sun. When we told you about experiencing 43C/114F in Egypt--that was measured in the shade. Measurements are in both metric and American except for wind speeds.

FYI, a sunny day is full sun. A 50% sunny day is partly cloudy--so two partly sunny days totals to one day of sun. Complete overcast is a zero.

This was a long hot summer. It felt worse than the data shows as far as humidity. There were a lot of days in Jul/Aug when we had no breezes, so the heat and humidity (comfort index) worsened. The humidity comes and goes. In comparison, we had more humidity (in the 50-60% range) this year than last year. Certainly not as miserable as in the American South—but you get spoiled living in the dry Western US for 40 years.

Oh, and thanks to Di--not only for being the blog queen--I have no idea how this gets onto a blog--but also for working hard to make the Excel spreadsheets I use for the weather data. I am in her debt once again. In the past, if I ever needed a spreadsheet at work, she would make it at home and I would email it to the office! Now I just have to keep her gin and tonics cold delivered on-time.  Guido, a weather geek in Southern Italy

  1. I'm not a weather geek, but I agree that it's very fascinating to watch seasons change. To see the differences between the years and do a little forecasting. :-)

    Wonderful rainbow btw.
