corresponding averages (thick lines), and with percentile bands (inner band

from 25th to 75th percentile, outer band from 10th to 90th percentile). The

bar at the top of the graph is red where both the daily high and low are

above average, blue where they are both below average, and white

otherwise.

The coldest dayofthe last 12 months was January 5, with a low

temperature of8C. For reference, on that day the average low

temperature is 13C and the low temperature drops below 10C onlyone day in ten. The coldest month ofthe last 12

months was January with an average daily low temperature of12C.

Relative to the average, the coldest day was March 22. The low

temperature that day was 14C, compared to the average of22C, adifference of8C. In relative terms the coldest month wasNovember,

with an average low temperature of16C, compared to an typicalvalue of18C.

The longest cold spellwas from March 7 to March 27, constituting 21consecutive days with cooler than average low temperatures. The

month ofNovember had the largest fraction of cooler than average

days with 90% days with lower than average low temperatures.

Hourly Temperature Bands

The full year of hourly temperature reports with the days of the year on the

horizontal and the hours of the day on the vertical. The hourly temperature

measurement is color coded into meaningful temperature bands: frigid ispurple (below-9C), freezing is blue (-9Cto0C), cold is dark green

(0Cto 10C), cool is light green (10Cto 18C), comfortable is yellow

(18Cto 24C), warm is light red (24Cto 29C), hot is medium red

(29Cto 38C), sweltering is dark red (above 38C), and missing data is

pink.

Clouds

The clearest month ofthe last 12 months was March, with 100% of

days being more clear than cloudy. The longest spell of clear weather

was from September 26 to January 1, constituting 98 consecutive days

that were clearer than they were cloudy.

Cloud Coverage

The fraction of time spent in each of the five sky cover categories over the

course ofthe last 12 months on a daily basis. From top (most blue) to

bottom (most gray), the categories are clear, mostly clear, partly cloudy,

mostly cloudy, and overcast. Pink indicates missing data. Outside of the

United States clear skies are often reported ambiguously, leading them to be

lumped in with the missing data. The bar at the top of the graph is gray if

the sky was cloudy or mostly cloudy for more than half the day, blue if it is

clear or mostly clear for more than half the day, and blue-gray otherwise.

The cloudiest month ofthe last 12 months was August, with 74% of

days being more cloudy than clear. The longest spell of cloudy weatherwas from August 7 to August 19, constituting 13 consecutive days that

were cloudier than they were clear.

Precipitation

This station provides hourly reports ofsignificant 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.Present Weather Reports

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, orin the case of solid precipitation that does not melt in the collection

basin.

The day in the last 12 months with the mostprecipitation

observations was August 12. There were 23 hourly weather reportsthat 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 wasSeptember, with 107 hourly present

weather reports involving some form of precipitation.

Precipitation Reports


5/10

The daily number of hourly observed precipitation reports during the last 12

months, color coded according to precipitation type, and stacked in order of

severity. From the bottom up, the categories are thunderstorms (orange);

heavy, moderate, and light snow (dark to light blue); heavy, moderate, and

light rain (dark to light green); and drizzle (lightest green). Not all

categories are necessarily present in this particular graph. The faint shaded

areas indicate climate normals. The bar at the top of the graph is green if

any precipitation was observed that day and white otherwise.

As determined by the present weather reports, the longest dry

spellwas from October 4 to February 14, constituting 134 consecutive

days with no observed precipitation. The months of February, March,

November, December, and January were completely without observedprecipitation.

The month with the largest fraction of days with at least someobserved precipitation was September, with 60% of days reporting

some observed precipitation.

Hourly Weather Reports

The full year of hourly present weather reports with the days of the year on

the horizontal and the hours of the day on the vertical. The color-coded

categories are thunderstorms (orange); heavy, moderate, and light snow

(dark to light blue); heavy, moderate, and light rain (dark to light green);

drizzle (lightest green); freezing rain and sleet (light and dark cyan); snow

grains (lightest blue); hail (red); fog (gray); and haze (brownish gray).

Snow

Either snow is exceptionally rare at this location or this station did not

reliably report it during the last 12 months.

Humidity

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'sskin.

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 ofthe last 12

months was March with an average daily low humidity of14%, and

themost humid month was September with an average daily low

humidity of64%.

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.

from 25th to 75th percentile, outer band from 10th to 90th percentile).

Dew Point

Dew point is the temperature below which water vapor will condenseinto 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 10C will feel a bit dry to some

people, but comfortable to people accustomed to dry conditions; dew

points from 10C to 20C are fairly comfortable to most people, and

dew points above 20C are increasingly uncomfortable, becomingoppressive around25C.

To take some examples, and basing our categorization on the daily

high dew point in the last 12 months, March had 8 dry days, 23

comfortable days, and no humid days; June had no dry days, no

comfortable days, and 30 humid days; September had no dry days, nocomfortable days, and 30 humid days; and December had no dry days,

30 comfortable days, and 1 humid day.

WindThe highest sustained wind speedwas 29 m/s, occurring on February

11; the highest daily mean wind speedwas 5 m/s (June 19); and the

highest wind gust speedwas 13 m/s (April 13).

The windiest month was June, with an average wind speed of4 m/s.

The least windy month wasOctober, with an average wind speed of1

m/s.

The daily low and high wind speed (light gray area) and the maximum daily

wind gust speed (tiny blue dashes).

Visibility

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 ofthe last 12 months with the lowest averagevisibilitywas March 21, with an average visibility of1.6 km. The month

with the lowest average visibility was September, with an average

visibility of3.7 km. With an average visibility of4.5 km, the month

ofJune had the highest average visibility.

Cloud Ceiling

The cloud ceiling is the altitude of the lowest layer of clouds that are atcategorized 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 ofthe last 12 months with the lowest average cloudceiling was June 3, with an average cloud ceiling of600 m. The month

with the lowest average cloud ceiling was June, with an average cloud

ceiling of1357 m. The month ofJanuary has the highest average cloud

ceiling, with an average cloud ceiling of2438 m.
