Temperatures, especially at night, have been noticeably cooler over the last week or so and Ngari says the island’s weather over the next few months is forecast to feature stronger-than-usual trade winds and more frequent cool spells than the last dry season.
Those winds will continue over the weekend as a ridge of high pressure from the southwest extending on to the southern Cook Islands that will bring strong south to southeast winds that may not die down , Ngari says.
“Associated with this is the plummeting of the air temperature by two degrees of normal that might require people to pull out those winter woollies in preparation for the cooler months.”
Ngari says last month’s mean temperature on Rarotonga was slightly higher than in May last year.
“The mean temperature for last month (24 degrees Celsius) was a degree higher compared to the same time last year, and the lowest temperature, recorded on May 19, was 15.4 degrees.”
Rainfall is still predicted to be reduced over the next three months especially for the Southern Cook Islands while the north will have an abundance of rain.
