Marlborough's hottest June day : and then another new record is set
The record for the hottest June day since the Marlborough “Windrushweather” station was established in 1984, was set on June 30 1995. But ….. no more! It's been a week of tumbling records.
Monday's record-breaking temperatures were overtaken on Wednesday (June 21) with a maximum of 32.2 degrees centigrade. And in 'old money' that temperature tipped Marlborough over the 90 degrees fahrenheit mark.
On Monday the thermometer soared steadily from dawn reaching a peak at 16.05 with a reading of 31.0C. But this was not the end of the extreme heat.
The high of 31.0C was maintained for an hour until just after 5pm when the thermometer inched even higher to a maximum of 31.4C at 17.25 breaking the previous record by 0.5C.
The sunshine was very strong (>100watts/sq.m.) throughout the day, triggering the sun recorder into action from 05.40. The total hours of strong sunshine amounted to 11.47, the second highest total this month after 14.72 hours were logged on the June 17.
Just before 6pm a few cumulous clouds bubbled up. Cumulus from the Latin for ‘heap’ or ‘pile’. These intermittently dimmed the sunshine allowing the thermometer to slowly fall.
The UV level has been peaking at the ‘Very High’ level for the past eleven days, the strongest of 9.9 occurred on June 11 and 16, Monday was lower at 8.3.
