A weak front slowly approached the island from the north all week and brought daily showers to the island for the last week. Some of those showers came with gusty winds with gusts measured over 40 kts at the airport. Isolated thunder was also in the area at times.

As of 3 am local time 26 July, the seven day rain total was 5.57″ at the Bermuda Weather Service – 3.63″ of that fell in the 24 hours ending at 3am local time. Most of that 3.63″ fell in the morning and late at night on the 25th. Keep in mind that 1971-2000 climatology has normal total monthly rainfall for July at 4.94″. The rains from this week’s slow moving/stationary front have completely erased the year-to-date rainfall deficit which was over 5″ at the start of the week.

Further, the rain and cloudiness kept temperatures quite low – a welcomed break from the heat and humidity that had set in on southwesterly flow around the Bermuda-Azores high and ahead of the front. In fact, rain cooled air led to a near record low temperature for the 25th of 72.1F – the record low stands at 69.1F set in 2007. The 1971-2000 normal low temperature for the 25th is ~78F.

Below are some rainfall measurements from unofficial sources around the island (via Wunderground) compared to the rain measured at the Bermuda Weather Service for the 24 hour period ending at 3am local time on 26 July.
