This Tuesday saw the highest daytime temperature recorded for September since 2005.

According to the Bermuda Weather Service (BWS), temperatures peaked at 87.6F (30.9C) — the highest since 2005, when 88.2F (31.2C) was recorded on September 5.

“The daytime maximum temperatures last year were higher on average than this year,” meteorologist Andrew Read said. “The 30.9C maximum this month, however, was the warmest since 2005.”

Mr Read said that last year temperatures rose above 86F (30C) on fifteen days while this year it has only been five days.

However, the average temperature for this month to date is still slightly higher at 81.1F (27.3C), compared to 80.2F (26.8C) last year.

“It is possible that the overall average temperature was slightly lower last year as there were cooler nights,” Mr Read said.

He added that September is typically one of the warmest months of the year with higher sea surface temperatures and relatively more humid days.

According to the BWS, temperatures are not unusual for this time of year with data showing that temperatures reached more than 87.6F on 91 occasions since 1981, the highest being 91.8F (33.2C) on September 3, 1994.

Data also suggests that rainfall levels are below average for September but Mr Read cautioned that this could still change.

“So far this month there has been 54mm (2.13 inches) of rain, but the month isn’t over and it is possible that there will be significant rainfall over the next few days, beginning Saturday night,” he said.

“It’s worth noting that a frontal boundary is expected to move through late Saturday, bringing strong winds, showers and possible thunderstorms.

“As this clears later Sunday there will be slightly lower temperatures and drier less humid air, providing some brief relief.”
