This report describes the historical weather record at the Seymour Johnson Air Force Base (Goldsboro, North Carolina, United States) during 1969. This station has records back to April 1954.
Goldsboro, North Carolina has a warm humid temperate climate with hot summers and no dry season. The area within 25 mi of this station is covered by croplands (74%), forests (24%), and built-up areas (2%)
Daylight saving time (DST) was observed at Goldsboro, North Carolina during 1969. There were two time changes during 1969:
1969 was not a leap year, so it has 365 days and no February 29th. The first leap year before 1969 was 1968 and the first after was 1972.
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 1969 they occurred on:

The clearest month of 1969 was March, with 58% of days being more clear than cloudy. The longest spell of clear weather was from July 13 to July 22, constituting 10 consecutive days that were clearer than they were cloudy.
The cloudiest month of 1969 was January, with 71% of days being more cloudy than clear. The longest spell of cloudy weather was from January 18 to February 4, constituting 18 consecutive days that were cloudier than they were clear.
This station provides hourly reports of significant weather events at and around the station, but does not report the quantity of precipitation at the station itself. This is common for weather stations located outside of the United States, and for a small subset of stations in the United States that are located at lesser used and smaller airports.
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 1969 with the most precipitation observations was January 20. 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 January, with 110 hourly present weather reports involving some form of precipitation.
As determined by the present weather reports, the longest dry spell was from August 21 to September 1, constituting 12 consecutive days with no observed precipitation. The month with the largest fraction of days without observed precipitation was January, with 74% of days reporting no observed precipitation at all.
The month with the largest fraction of days with at least some observed precipitation was June, with 57% 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 1969 with the largest number of those reports was January, with a total of 103 reports. The day with the largest number of those reports was January 20, 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 1969 was on January 4; the last was on March 2. The month of 1969 with the largest number of those reports was February, with a total of 11 reports. The day with the largest number of those reports was January 4, with a total of 7 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 1969 was March with an average daily low humidity of 30%, and the most humid month was August with an average daily low humidity of 58%.
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 1969, January had 24 dry days, 7 comfortable days, and no humid days; April had 10 dry days, 20 comfortable days, and no humid days; July had no dry days, no comfortable days, and 31 humid days; and October had 6 dry days, 16 comfortable days, and 9 humid days.
The highest sustained wind speed was 25 mph, occurring on March 25; the highest daily mean wind speed was 15 mph (March 25);
The windiest month was February, with an average wind speed of 8 mph. The least windy month was June, 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 1969 with the lowest average visibility was December 8, with an average visibility of 0.9 mi. The month with the lowest average visibility was September, with an average visibility of 5.5 mi. With an average visibility of 6.6 mi, the month of November 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 1969 with the lowest average cloud ceiling was September 15, with an average cloud ceiling of 108'. The month with the lowest average cloud ceiling was May, with an average cloud ceiling of 5298'. The month of March has the highest average cloud ceiling, with an average cloud ceiling of 8809'.
