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 1985 with the most precipitation observations was February 5. There were 21 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 February, with 71 hourly present weather reports involving some form of precipitation.
As determined by the present weather reports, the longest dry spell was from December 14 to December 28, constituting 15 consecutive days with no observed precipitation. The month with the largest fraction of days without observed precipitation was December, with 77% 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 52% of days reporting some observed precipitation.
Either snow is exceptionally rare at this location or this station did not reliably report it during 1985.
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 1985 was April with an average daily low humidity of 38%, and the most humid month was November with an average daily low humidity of 59%.
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 1985, January had 23 dry days, 8 comfortable days, and no humid days; April had 7 dry days, 22 comfortable days, and 1 humid day; July had no dry days, 2 comfortable days, and 29 humid days; and October had 2 dry days, 7 comfortable days, and 22 humid days.
The highest sustained wind speed was 57 mph, occurring on April 5; the highest daily mean wind speed was 19 mph (September 1); and the highest wind gust speed was 40 mph (May 21).
The windiest month was February, with an average wind speed of 10 mph. The least windy month was July, 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 1985 with the lowest average visibility was January 3, with an average visibility of 2.5 mi. The month with the lowest average visibility was November, with an average visibility of 6.2 mi. With an average visibility of 8.5 mi, the month of December 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 1985 with the lowest average cloud ceiling was June 3, with an average cloud ceiling of 49'. The month with the lowest average cloud ceiling was November, with an average cloud ceiling of 6125'. The month of July has the highest average cloud ceiling, with an average cloud ceiling of 14040'.
