Relative to the average, the coldest day was January 11. The low temperature that day was 15°F, compared to the average of 44°F, a difference of 29°F. In relative terms the coldest month was September, with an average low temperature of 70°F, compared to an typical value of 72°F.
The longest cold spell was from July 29 to August 14, constituting 17 consecutive days with cooler than average low temperatures. The month of July had the largest fraction of cooler than average days with 71% days with lower than average low temperatures.
The clearest month of 1982 was October, with 19% of days being more clear than cloudy. The longest spell of clear weather was from October 23 to October 27, constituting 5 consecutive days that were clearer than they were cloudy.
The cloudiest month of 1982 was March, with 77% of days being more cloudy than clear. The longest spell of cloudy weather was from November 16 to December 5, constituting 20 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 1982 with the most precipitation observations was February 2. 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 July, with 144 hourly present weather reports involving some form of precipitation.
As determined by the present weather reports, the longest dry spell was from February 17 to February 26, constituting 10 consecutive days with no observed precipitation. The month with the largest fraction of days without observed precipitation was May, 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 July, with 81% of days reporting some observed precipitation.
Either snow is exceptionally rare at this location or this station did not reliably report it during 1982.
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 1982 was October with an average daily low humidity of 52%, and the most humid month was July with an average daily low humidity of 66%.
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 1982, January had 9 dry days, 22 comfortable days, and no humid days; April had 1 dry day, 15 comfortable days, and 14 humid days; July had no dry days, no comfortable days, and 31 humid days; and October had 5 dry days, 10 comfortable days, and 16 humid days.
The highest sustained wind speed was 23 mph, occurring on May 7; the highest daily mean wind speed was 13 mph (November 4); and the highest wind gust speed was 39 mph (June 28).
The windiest month was December, with an average wind speed of 8 mph. The least windy month was July, 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 1982 with the lowest average visibility was January 3, with an average visibility of 0.4 mi. The month with the lowest average visibility was January, with an average visibility of 4.9 mi. With an average visibility of 6.6 mi, the month of September 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 1982 with the lowest average cloud ceiling was February 23, with an average cloud ceiling of 49'. The month with the lowest average cloud ceiling was February, with an average cloud ceiling of 5562'. The month of June has the highest average cloud ceiling, with an average cloud ceiling of 19125'.
