This report describes the historical weather record at the Yoro Airport (Yoro, Honduras) during 2012. This station has records back to April 1983.
Yoro has a tropical savanna climate with dry winters. The area within 25 mi of this station is covered by croplands (65%), forests (30%), and marshes (3%)
Daylight saving time (DST) was not observed at Yoro during 2012.
2012 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 2012 February 29th falls on a Wednesday.
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 2012 they occurred on:
|Spring Equinox||Tuesday, 20 March 2012.|
|Summer Solstice||Wednesday, 20 June 2012.|
|Fall Equinox||Saturday, 22 September 2012.|
|Winter Solstice||Friday, 21 December 2012.|
The hottest day of 2012 was May 8, with a high temperature of 95°F. For reference, on that day the average high temperature is 90°F and the high temperature exceeds 94°F only one day in ten. The hottest month of 2012 was September with an average daily high temperature of 87°F.
The longest warm spell was from December 14 to December 21, constituting 8 consecutive days with warmer than average high temperatures. The month of December had the largest fraction of warmer than average days with 71% days with higher than average high temperatures.
The coldest day of 2012 was December 24, with a low temperature of 50°F. For reference, on that day the average low temperature is 62°F and the low temperature drops below 59°F only one day in ten. The coldest month of 2012 was December with an average daily low temperature of 61°F.
The longest cold spell was from September 11 to October 3, constituting 23 consecutive days with cooler than average low temperatures. The month of September had the largest fraction of cooler than average days with 80% days with lower than average low temperatures.
This station did not reliably report the cloud coverage during 2012 but there is enough reported data to warrant the inclusion of the following graphs.
The cloudiest month of 2012 was November, with 27% of days being more cloudy than 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 October 21. That day saw 0.512" of liquid (or liquid equivalent) precipitation, compared to a median value of 0.079". The month with the most precipitation was October, with 0.866", compared to a median value of NaN".
As determined by quantitative measurements, the longest dry spell was from January 1 to June 14, constituting 166 consecutive days with no measured precipitation. The months January, February, March, April, May, July, September, November, and December were completely without measured precipitation.
The month with the largest fraction of days with at least some measured precipitation was October, with 10% 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 2012 with the most precipitation observations was August 29. There were 6 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 August, with 20 hourly present weather reports involving some form of precipitation.
As determined by the present weather reports, the longest dry spell was from January 1 to March 6, constituting 66 consecutive days with no observed precipitation. The months January, February, and December were completely without observed precipitation.
The month with the largest fraction of days with at least some observed precipitation was June, with 33% of days reporting some observed precipitation.
Either snow is exceptionally rare at this location or this station did not reliably report it during 2012.
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 2012 was March with an average daily low humidity of 45%, and the most humid month was January with an average daily low humidity of 78%.
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 2012, January had no dry days, 1 comfortable day, and 3 humid days; April had no dry days, 7 comfortable days, and 11 humid days; July had no dry days, no comfortable days, and 21 humid days; and October had no dry days, 5 comfortable days, and 26 humid days.
The highest sustained wind speed was 18 mph, occurring on February 17; the highest daily mean wind speed was 16 mph (January 3);
The windiest month was January, with an average wind speed of 8 mph. The least windy month was October, with an average wind speed of 3 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 2012 with the lowest average visibility was April 15, with an average visibility of 0.6 mi. The month with the lowest average visibility was April, with an average visibility of 6.3 mi. With an average visibility of 6.7 mi, the month of February 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 2012 with the lowest average cloud ceiling was January 3, with an average cloud ceiling of 1969'. The month with the lowest average cloud ceiling was January, with an average cloud ceiling of 4921'. The month of April has the highest average cloud ceiling, with an average cloud ceiling of 10125'.
