NWS: Indian Summer

"An early American writer described Indian Summer well when he wrote, "The air is perfectly quiescent and all is stillness, as if Nature, after her exertions during the Summer, were now at rest." This passage belongs to the writer John Bradbury and was written nearly an "eternity" ago, back in 1817. But this passage is as relevant today as it was way back then. The term "Indian Summer" dates back to the 18th century in the United States. It can be defined as "any spell of warm, quiet, hazy weather that may occur in October or even early November." Basically, autumn is a transition season as the thunderstorms and severe weather of the summer give way to a tamer, calmer weather period before the turbulence of the winter commences."

"The term "Indian Summer" is generally associated with a period of considerably above normal temperatures, accompanied by dry and hazy conditions ushered in on a south or southwesterly breeze. Several references make note of the fact that a true Indian Summer can not occur until there has been a killing frost/freeze. Since frost and freezing temperatures generally work their way south through the fall, this would give credence to the possibility of several Indian Summers occurring in a fall, especially across the northern areas where frost/freezes usually come early."

Google Maps: Length Of Day In New York State On the First Day of Autumn

The first day of autumn does not have exactly 12 hours day and 12 hours of night. There is about 12 hours and 7 minutes of daylight, depending on what part of New York State you are to celebrate the autumn equinox due to refraction of light on the earth's atmosphere. This is The Town of Massena will have the longest day in all of New York State, at 12 hours, 7 minutes and 54 seconds. The Borough of Staten Island will have shortest day, at 12 hours, 7 minutes and 29 seconds. On Wednesday, September 27th this reverses -- the day will actually be slightly longer in Staten Island then Massena.

September Record Low Temperatures

This graph shows the record lows in Albany.

The first recorded frost in Albany, NY is next Wednesday, September 14th. Albany hit 32 degrees on September 14, 1963. The autumn of 1963 was a pretty cold one in Albany, we broke several record lows that year, with temperatures well below freezing on several mornings in late September 1963. Overall, 1963 is the coldest September with complete records at the Albany International Airport. 1835 was recorded as being slightly colder, but those observations were done downtown rather in then Colonie. The coldest September morning in Albany was September 24 and 25 during 1947, when temperatures dropped down to 24 degrees.

Good morning! Happy Thursday. Next Thursday the Average High is 70. And the following day is the first day of autumn. Cloudy and 69 degrees in Delmar, NY. A break in the clouds earlier but now it’s gone. There is a south breeze at 6 mph. The dew point is 63 degrees. With the relatively high dew point, it feels like a damp mid-summer day. Like you might have on a cold, wet July day. The skies will clear tomorrow around 3 pm.

The air conditioning feels good on the bus because it was a but sticky when I awoke. It wasn’t a terrible walk down to the bus stop and the bus was running close to on time. Maybe a minute or two late but that’s not uncommon during the school year. Just a regular 40 foot bus downtown, not the big 75-person articulated bus that they have been running regularly on express route. There was a three car crash on the 9W bridge into the city and while there was minor tie ups, we got moving quickly. I’m just glad that I didn’t have to navigate it.

Today will have a slight chance of showers, then a chance of showers and thunderstorms after 9am. Mostly cloudy, with a high of 75 degrees at 3pm. Two degrees above normal. I brought my rain coat to be safe. Going to be fairly humid day with a muggy maximum dew point of 66 at 11am. South wind 6 to 8 mph. Chance of precipitation is 40%. New rainfall amounts between a tenth and quarter of an inch, except higher amounts possible in thunderstorms. A year ago, we had mostly cloudy skies. It was somewhat humid. The high last year was 82 degrees. Pretty close to today but still much warmer than today. The record high of 93 was set in 1931.

The sun will set at 7:05 pm with dusk around 7:34 pm, which is one minute and 46 seconds earlier than yesterday. At sunset, look for cloudy conditions and 70 degrees. The dew point will be 63 degrees. There will be a south breeze at 7 mph. Today will have 12 hours and 30 minutes of daytime, an decrease of 2 minutes and 50 seconds over yesterday.

Tonight will have a chance of showers, mainly before 2am. Mostly cloudy, with a low of 62 degrees at 4am. 10 degrees above normal. Maximum dew point of 64 at 6pm. South wind around 6 mph becoming calm after midnight. Chance of precipitation is 40%. New precipitation amounts between a tenth and quarter of an inch possible. In 2016, we had mostly clear skies. It got down to 48 degrees. The record low of 33 occurred back in 1975.

Tonight I will get packed for heading up to the Adirondacks. I expect I will buy firewood tomorrow, because I won’t be able to get set up at camp until after dark. It will be dusk about the time I’m most of the way up there, but I’ll drive slow, keep my eye out for deer, and will make it up there safely. I don’t mind setting up in the dark, especially because I have the electric lights that are easy to set up, and can use the propane lantern for additional light when preparing dinner and getting the fire started.

I am definitely looking forward to exploring Moss Island on Saturday. Should be a nice weekend, with lots of warmth and sun. You don’t always get great weekends like this in September, but when you do you really got to take advantage of them.

As previously noted, next Thursday the Average High is 70 when the sun will be setting at 6:53 pm with dusk at 7:21 pm. On that day in 2016, we had mostly cloudy skies and temperatures between 80 and 58 degrees. Typically, the high temperature is 70 degrees. We hit a record high of 95 back in 1895.

Google Maps: Length Of Day On The First Day Of Fall

I thought we should put the old myth to bed -- on the first day of autumn that all of earth has the same length of day, and it's always 12 hours of daylight and 12 hours of darkness. That is not exactly true -- due to refraction of sunlight on the earth's atmosphere, almost all of the world has more then 12 hours of daylight. Towards the poles, you have around 12 hours and 10 minutes of daylight, while closer to the equator, you have more like 12 hours and 6 minutes of daylight. This interactive map will help you understand the length of day, and when to expect the sunrise and sunset on that day.

Length of Day, Next Month

The first day when we will have more night then day will be Monday, September 25th. This is due to the refraction of the sun on the earth -- we don't have exactly 12 hours of daylight and 12 hours of night on the first day of autumn. Indeed, it varies a bit on how much day length on the first day of autumn as you travel to different parts of New York State, depending on how far from your from the equator.

Good morning! Today should be a really nice Wednesday, once the fog burns off. It will be mostly sunny, with temperatures around 80 degrees expected by afternoon. Believe it or not, the humidity will be creeping up this afternoon, and by evening it might even feel a bit sticky. Might not be quite as warm as the 83 degrees we had last year, but it’s still well above the 74 degrees that’s normal for this time of year.

I was glad that I had a fresh pot of coffee to start out the morning. Because I was low on coffee, the past few days my coffee has been weak, and I think the fact that I buy coffee in bulk, after 3-4 months of going through the container, the last bit of coffee isn’t the potent. But I sure love reusing those containers for making ice. They are quite waterproof and do not leak like the plastic milk bottles.

The sun will set at 7:07 pm with dusk around 7:35 pm, which is one minute and 47 seconds earlier than yesterday. At sunset, look for partly cloudy conditions and 72 degrees. The dew point will be 62 degrees. There will be a south breeze at 5 mph. That would be perfect for going down to the park, except sunset is expected so early. Today will have 12 hours and 33 minutes of daytime, an increase of 2 minutes and 51 seconds over yesterday.

Tonight will have a slight chance of showers. Mostly cloudy, with a low of 63 degrees at 3am. 11 degrees above normal. Maximum dew point of 62 at 6pm. South wind around 6 mph. Chance of precipitation is 20%. In 2016, we had mostly cloudy skies, clearing in the early hours of the next day. It was somewhat humid. It got down to 53 degrees. The record low of 32 occurred back in 1963.

The weekend still looks nice. I plan to get packed and will head out from work on Friday. I may or may not leave early, I’m undecided but I will drive straight to Amsterdam on the Thruway to save time and buy firewood in advance. This way, I will avoid driving in the dark, and will be able to set up quickly, even if it’s after dusk (and it may be raining). The weekend does look beautiful for sure. After so many rainy summer weekends, a change sure is nice.

Looking ahead, there are 3 weeks until 6:30 PM Sunset when the sun will be setting at 6:30 pm with dusk at 6:58 pm. On that day in 2016, we had cloudy skies and temperatures between 69 and 53 degrees. Typically, the high temperature is 65 degrees. We hit a record high of 86 back in 1891.
