Cold weather coming after a warm spell
Temperatures will be rising this week after a bitterly cold weekend, but the worst of the cold may be yet to come, according to the Bermuda Weather Service.
A high of 70F is forecast for Saturday, with a low of 64F, much higher than Monday’s high of 62.6F and a low of 52.5F.
Michelle Pitcher, the director of the BWS, said that Monday, while chilly, “doesn’t even place in the top 50 coldest days”.
She added that the coldest month in the year is normally February, with an average temperature of 63.9F, or 17.7C, between 1981 and 1995.
February is also the month with Bermuda’s coldest temperature on record, which was a low of 43.3F, or 6.3C.
Dr Pitcher warned that as winter continues, Bermudians could experience colder days than those over the past few days.
She added that wind chill, though often not reported by the BWS unless it involved life-threatening cold, could also pay a factor in the weather feeling colder than it actually is.
Wind chill is linked to the “real-feel” or “feels-like” temperature during colder months.
Although the “real-feel” temperature has no clear definition and varies around the world, it combines the measured air temperature, humidity and wind speed.
In Britain, it is calculated by adjusting the air temperature to the understanding of wind chill in low temperatures or the heat index in higher temperatures.
Britain uses Joint Action Group for Temp Indices to measure wind chill by looking at how much heat is lost from a person’s bare face at a walking speed of 3mph.
Stronger winds lead to greater feelings of cold.
When wind speed is low during periods of high temperatures, the humidity level is instead examined.
Higher humidity slows the level of evaporation from the skin, which retains body heat and makes a person feel warmer.
