It meant it was the hottest day since July 2, 2009, when a sunny 24.1C (75F) was recorded at the airport. In addition, further inland on Saturday, it reached as high as a scorching 25C (77F). The following day was another warm day, with the temperature rising to 19.5C (67F) at the airport.
It was well above the average May temperature of 17C (62F).
And it smashed the hottest day reached in the Island so far this year. That was achieved on Thursday, May 6, when 16C (60F) was recorded at the airport. Many Isle of Man residents flocked to the Island's beaches to enjoy the warm weather.
But there was bad news for those hoping that the weekend's weather was the start of sunny summer. On Monday morning, a Met Office spokesman said that the wind direction had already changed. It means that the temperatures forecast for the week are getting increasing cooler, from a maximum of 14C (57F) today (Tuesday) to 13C (55F) by Friday.
There is a chance of rain on Thursday and Friday.
