This report describes the historical weather record at the Tulsa International Airport (Tulsa, Oklahoma, United States) during 1952. This station has records back to December 1947.
Tulsa, Oklahoma has a warm humid temperate climate with hot summers and no dry season. The area within 25 mi of this station is covered by grasslands (79%), forests (11%), built-up areas (7%), and lakes and rivers (3%)
Daylight saving time (DST) was observed at Tulsa, Oklahoma 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:

|Summer Solstice||Saturday, 21 June 1952.|
|Fall Equinox||Tuesday, 23 September 1952.|
|Winter Solstice||Sunday, 21 December 1952.|

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 June 5. That day saw 3.220" of liquid (or liquid equivalent) precipitation, compared to a median value of 0.261". The month with the most precipitation was April, with 4.390", compared to a median value of 3.173".
As determined by quantitative measurements, the longest dry spell was from September 22 to November 8, constituting 48 consecutive days with no measured precipitation. The month October were completely without measured precipitation.
The month with the largest fraction of days with at least some measured precipitation was March, with 35% 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 November 24. There were 23 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 April, with 96 hourly present weather reports involving some form of precipitation.
As determined by the present weather reports, the longest dry spell was from October 6 to November 8, constituting 34 consecutive days with no observed precipitation. The month with the largest fraction of days without observed precipitation was October, with 97% of days reporting no observed precipitation at all.
The month with the largest fraction of days with at least some observed precipitation was May, with 55% 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 96 reports. The day with the largest number of those reports was November 24, with a total of 23 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 November 25; the last was on March 14. The month of 1952 with the largest number of those reports was January, with a total of 23 reports. The day with the largest number of those reports was January 2, with a total of 13 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 October with an average daily low humidity of 20%, and the most humid month was December with an average daily low humidity of 50%.
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 21 dry days, 10 comfortable days, and no humid days; April had 15 dry days, 15 comfortable days, and no humid days; July had no dry days, 5 comfortable days, and 26 humid days; and October had 28 dry days, 3 comfortable days, and no humid days.
The highest sustained wind speed was 35 mph, occurring on March 12; the highest daily mean wind speed was 23 mph (March 22);
The windiest month was March, with an average wind speed of 13 mph. The least windy month was September, with an average wind speed of 9 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 8, with an average visibility of 3.3 mi. The month with the lowest average visibility was February, with an average visibility of 11.3 mi. With an average visibility of 14.4 mi, the month of August had the highest average visibility.
The cloud ceiling is the altitude of the lowest layer of clouds that are at categorized as broken (mostly cloudy) or overcast (cloudy). If no such cloud layer exists then the ceiling is unlimited and no value is reported.
The day of 1952 with the lowest average cloud ceiling was December 3, with an average cloud ceiling of 506'. The month with the lowest average cloud ceiling was February, with an average cloud ceiling of 7542'. The month of September has the highest average cloud ceiling, with an average cloud ceiling of 18582'.
