This report describes the historical weather record at the Dutchess County Airport (Poughkeepsie, New York, United States) during 1952. This station has records back to January 1949.
Poughkeepsie, New York has a humid continental climate with warm summers and no dry season. The area within 25 mi of this station is covered by forests (94%), lakes and rivers (3%), and built-up areas (2%)
Daylight saving time (DST) was observed at Poughkeepsie, New York during 1952. There were two time changes during 1952:
1952 was a leap year and thus has 366 days rather than the normal 365. Leap years occur every fourth year and the extra day is always February 29th. In 1952 February 29th falls on a Friday.
The summer and winter solstices and the spring and fall equinoxes mark the passing of the seasons. They fall on nearly the same day each year, with differences of a day or two depending on the year. In 1952 they occurred on:
|Spring Equinox||Thursday, 20 March 1952.|
|Summer Solstice||Saturday, 21 June 1952.|
|Fall Equinox||Tuesday, 23 September 1952.|
|Winter Solstice||Sunday, 21 December 1952.|

The longest cold spell was from February 22 to March 3, constituting 11 consecutive days with cooler than average low temperatures. The month of October had the largest fraction of cooler than average days with 84% days with lower than average low temperatures.
The clearest month of 1952 was September, with 43% of days being more clear than cloudy. The longest spell of clear weather was from October 21 to October 27, constituting 7 consecutive days that were clearer than they were cloudy.
The cloudiest month of 1952 was April, with 77% of days being more cloudy than clear. The longest spell of cloudy weather was from March 3 to March 12, constituting 10 consecutive days that were cloudier than they were clear.
This station reports both the quantity of liquid precipitation and categorical observations of precipitation (e.g., moderate rain, or heavy snow). Both are subject to erroneous reports, but the former is particularly prone to false reports, especially ones indicating an excessive quantity of precipitation. Please bear this in mind when reading the extrema reported in this section.
The day with the largest quantity of precipitation was September 1. That day saw 2.402" of liquid (or liquid equivalent) precipitation, compared to a median value of 0.094". The month with the most precipitation was April, with 6.996", compared to a median value of 2.933".
As determined by quantitative measurements, the longest dry spell was from October 3 to October 28, constituting 26 consecutive days with no measured precipitation. The month with the largest fraction of dry days was October, with 90% of days reporting no measured precipitation at all.
The month with the largest fraction of days with at least some measured precipitation was January, with 45% of days reporting some measured precipitation.
This station reports when significant weather events (including precipitation) are visually observed at or near the station. Such events do not always correspond to measured quantities of liquid equivalent precipitation, such as when the event is near by not at the station, or in the case of solid precipitation that does not melt in the collection basin.
The day in 1952 with the most precipitation observations was January 26. There were 22 hourly weather reports that day (out of a maximum of 24) in which some form of precipitation was observated at or near the station. The month with the most precipitation observations was January, with 137 hourly present weather reports involving some form of precipitation.
As determined by the present weather reports, the longest dry spell was from October 14 to October 28, constituting 15 consecutive days with no observed precipitation. The month with the largest fraction of days without observed precipitation was October, with 87% of days reporting no observed precipitation at all.
The month with the largest fraction of days with at least some observed precipitation was January, with 65% of days reporting some observed precipitation.
In this section we consider only those weather reports that indicate liquid precipitation. For the purposes of this analysis, we include thunderstorms even though some thunderstorms are not accompanied by liquid precipitation.
The month of 1952 with the largest number of those reports was April, with a total of 135 reports. The day with the largest number of those reports was January 26, with a total of 20 reports.
This station reports when snow is observed falling but does not report the quantity of snow that has fallen or the depth of snow on the ground.
In this section we consider hourly weather reports that contain an observation of falling snow. These reports do not necessarily correspond to accumulation.
The first reported snow fall in 1952 was on October 28; the last was on March 19. The month of 1952 with the largest number of those reports was March, with a total of 66 reports. The day with the largest number of those reports was February 21, with a total of 18 reports.
Humidity is an important factor in determining how weather conditions feel to a person experiencing them. Hot and humid days feel even hotter than hot and dry days because the high level of water content in humid air discourages the evaporation of sweat from a person's skin.
When reading the graph below, keep in mind that the hottest part of the day tends to be the least humid, so the daily low (brown) traces are more relevant for understanding daytime comfort than the daily high (blue) traces, which typically occur during the night. Applying that observation, the least humid month of 1952 was May with an average daily low humidity of 42%, and the most humid month was January with an average daily low humidity of 62%.
But it is important to keep in mind that humidity does not tell the whole picture and the dew point is often a better measure of how comfortable a person will find a given set of weather conditions. Please see the next section for continued discussion of this point.
Dew point is the temperature below which water vapor will condense into liquid water. It is therefore also related to the rate of evaporation of liquid water. Since the evaporation of sweat is an important cooling mechanism for the human body, the dew point is an important measurement for understanding how dry, comfortable, or humid a given set of weather conditions will feel.
Generally speaking, dew points below 50°F will feel a bit dry to some people, but comfortable to people accustomed to dry conditions; dew points from 50°F to 68°F are fairly comfortable to most people, and dew points above 68°F are increasingly uncomfortable, becoming oppressive around 77°F.
To take some examples, and basing our categorization on the daily high dew point in 1952, January had 29 dry days, 2 comfortable days, and no humid days; April had 19 dry days, 11 comfortable days, and no humid days; July had no dry days, 6 comfortable days, and 25 humid days; and October had 21 dry days, 10 comfortable days, and no humid days.
The highest sustained wind speed was 32 mph, occurring on May 21; the highest daily mean wind speed was 16 mph (February 12);
The windiest month was March, with an average wind speed of 8 mph. The least windy month was September, with an average wind speed of 4 mph.
Visibility is the maximum distance at which a given reference object or light can be clearly discerned. In the United States, visibilities that are greater than or equal to 10 miles are typically reported as 10 miles.
The day of 1952 with the lowest average visibility was November 16, with an average visibility of 0.9 mi. The month with the lowest average visibility was November, with an average visibility of 8.9 mi. With an average visibility of 11.6 mi, the month of May had the highest average visibility.
This station did not reliably report the cloud ceiling during 1952.
