A Hat-trick of Sub-Twenty Temperatures for most of Antigua and Barbuda

Last night’s cold weather makes it a hat-trick of sub-twenty temperatures for most of Antigua and Barbuda. This is a fairly rare feat for the country. It has only happened seven other times during January, based on historical data for the Airport. The last time it happened in January was back in 1996 – 20 years ago. The last time it happened for any month was in March 2000.jan2017temperatureWhereas the last hat-trick of sub-twenty temperatures occurred last in January 1996, the coolest such period last took place in 1992. It is also the coolest such period, for all months, last occurred in March 2000. This and the rest of what is said here is an update on the previous blog.

The mean minimum temperature for the past three nights, at the Airport, was 18.5 °C (65.3 °F). This is the eighth coldest for three or more days in a row with sub-twenty temperatures at the Airport. Further, it is the 12 coldest for any three-day sub-twenty spell (overlapping and otherwise).

When we consider such a three-peat of sub-twenty temperatures for all months dating back to 1971, it has only happened 27 previous times.

So far for January, the mean minimum temperature at the Airport of 22.0 °C (72 °F) is below normal. However, up to three days ago, it was bordering on above normal – meaning we were having relatively warm nights for this time of the year. The mean daily temperature is well below normal with a value of 24.7 °C (76.5 °F).

As cold as it has been, it certainly has NOT nearly been cold enough to freeze water. Thus, that picture being circulated suggesting that the cold weather caused a small body of water to freeze in Free Town is a HOAX. For this to happen, we would need to have sub-zero temperatures persisting for days, which will NEVER happen.

There have only being five occasions when sub-twenty degree nights have occurred for more than three consecutive nights. Tonight is likely to be the sixth time this has happened. So far, today has been coldest of the past three days.

After tonight, the weather will warmup to usual temperatures for this time of the year. Then the cold weather will more likely than not return on Wednesday and continue on Thursday. Thereafter, the usual temperatures for this time of the year is expected to prevail for the rest of the month.

Although we are unable to say definitively how cold the country or specific areas have been due scarcity of historical temperature data, it is likely the coldest since 1996. This is based on fact that temperatures across a small homogeneous area like Antigua and Barbuda are highly correlated. And since it is the coldest for the Airport since 1992, it should be likewise for the rest of the islands.

From a quantitative standpoint, the statements above are truest for the Airport and surrounding areas; however, from a qualitative assessment, it is applicable to the rest of the country.

Near Record Temperatures Over the Past 24 Hours!

2 03 2013

Many parts of Antigua had near record temperatures over the last 24 hours. Last night the minimum temperature dropped to 19.2C/66.6F. This was the second coldest night for March 1, based on record dating back to 1971; it was also the second coldest night, so far, for the year. The coolest temperature on record for this day is 18.8C/65.8F measured in 2000. A combination of things came together to cause this near record cold night: Cold air from North America, calm or near calm overnight wind and a relatively dry atmosphere.

Meanwhile, today (March 2) had a near record high temperature with a value of 29.8C/85.6F. This was the second warmest March 2 on record. The record for this day is 30.4C/86.7F in 2010. The main reason for this near record high temperature was the light east to east-southeasterly wind.

We will not likely see a repeat of these values over the next 24 hours; however, the weather pattern suggests that next week (by Antigua standards) will be quite quite warm during the day and quite cold at night. Records could be broken; 32.9C/91.2F (2010)and 17.0C/62.6F (2000) are the highest and lowest temperatures respectively for March.
