This report describes the historical weather record at the Meadows Field Airport (Bakersfield, California, United States) during 1948. This station has records back to January 1948.
Bakersfield, California has a hot desert climate. The area within 25 mi of this station is covered by grasslands (38%), croplands (30%), shrublands (19%), and forests (12%)
Daylight saving time (DST) was observed at Bakersfield, California during 1948. There was only one time change during 1948: daylight saving time started on Sunday March 14, 1948 at 3:00 am, from GMT-8 to GMT-7.
1948 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 1948 February 29th falls on a Sunday.
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 1948 they occurred on:
|Spring Equinox||Saturday, 20 March 1948.|
|Summer Solstice||Monday, 21 June 1948.|
|Fall Equinox||Thursday, 23 September 1948.|
|Winter Solstice||Tuesday, 21 December 1948.|

The clearest month of 1948 was August, with 100% of days being more clear than cloudy. The longest spell of clear weather was from July 28 to September 14, constituting 49 consecutive days that were clearer than they were cloudy.
The cloudiest month of 1948 was December, with 55% of days being more cloudy than clear. The longest spell of cloudy weather was from December 20 to December 24, constituting 5 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 December 27. That day saw 0.197" of liquid (or liquid equivalent) precipitation, compared to a median value of 0.083". The month with the most precipitation was December, with 0.516", compared to a median value of 0.813".
As determined by quantitative measurements, the longest dry spell was from January 1 to October 11, constituting 285 consecutive days with no measured precipitation. The months January, February, March, April, May, June, July, August, September, and November were completely without measured precipitation.
The month with the largest fraction of days with at least some measured precipitation was December, with 16% 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 1948 with the most precipitation observations was March 17. There were 11 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 March, with 66 hourly present weather reports involving some form of precipitation.
As determined by the present weather reports, the longest dry spell was from August 1 to October 11, constituting 72 consecutive days with no observed precipitation. The months August, September, and November were completely without observed precipitation.
The month with the largest fraction of days with at least some observed precipitation was March, with 42% of days reporting some observed precipitation.
Either snow is exceptionally rare at this location or this station did not reliably report it during 1948.
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 1948 was July with an average daily low humidity of 16%, and the most humid month was December with an average daily low humidity of 49%.
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 1948, January had 24 dry days, 7 comfortable days, and no humid days; April had 23 dry days, 7 comfortable days, and no humid days; July had 6 dry days, 25 comfortable days, and no humid days; and October had 13 dry days, 18 comfortable days, and no humid days.
The highest sustained wind speed was 40 mph, occurring on December 26; the highest daily mean wind speed was 25 mph (December 26);
The windiest month was April, with an average wind speed of 9 mph. The least windy month was January, with an average wind speed of 6 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 1948 with the lowest average visibility was December 29, with an average visibility of 1.8 mi. The month with the lowest average visibility was January, with an average visibility of 11.5 mi. With an average visibility of 29.8 mi, the month of April 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 1948 with the lowest average cloud ceiling was December 29, with an average cloud ceiling of 527'. The month with the lowest average cloud ceiling was December, with an average cloud ceiling of 3004'. The month of July has the highest average cloud ceiling, with an average cloud ceiling of 21099'.
