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. Remember to please take our weather survey: click for weather survey

It was Hell Today – Did You Notice?

4 09 2012

Hot like hell! Today’s (4Sep, 2012) maximum temperature shattered the previous record for September. Today’s maximum of 34.3°C/93.7°F is now the highest on record (1971-2012) for September going well pass the month’s previous high of 33.5°C/92.3°F. It was also the second highest temperature on record for all months. Only August of 2005 had a higher maximum temperature with 34.9°C/94.8°F. In terms of how it actually felt to the human body; the heat index is a measure of this, and it peaked at 37°C/99°F. So although the maximum was 34.3°C/93.7°F, it really felt like 37°C/99°F. The heat index is a function of the temperature and the relative humidity. Today’s humidity was low; in the 40’s and 50’s; if it were higher, the heat index would have been higher and conditions would have been much more miserable even dangerous (http://en.wikipedia.org/wiki/Heat_index).

The conditions that led to today’s maximum temperature were light southerly wind and few low level clouds. These conditions were caused by the proximity of Tropical Storm Leslie between the Caribbean and Bermuda.

Conditions for the next four days are expected to be similar to today – light southerly winds and few low level clouds; hence, the rest of the week is expected to have above normal temperatures. These temperatures and resultant heat indices could reach dangerous levels. Residents should take precautions (http://www.epa.gov/heatisland/about/pdf/EHEguide_final.pdf)
