Sydney is having a very dry start to the month with no rain recorded in the gauge since the 25th of April.
This is very unusual for May and is the result of a series of high pressure systems moving over the city and keeping rain bearing systems away.
The last time we experienced such a dry start to May was in 2008, when the first day of reported precipitation was the 15th day of the month. A total of three millimetres fell over the month of May in 2008, with just 5 rain days. The average May rainfall is 121 mm, with 13 rain days.
The outlook for Sydney is for a mostly sunny weekend, albeit a little cooler. There is the chance of a very light shower on Sunday night due to the tail end of a cold front pushing through. The best chance of a shower in the near future is on Wednesday, when winds tend more easterly bringing in more moisture from the Tasman Sea.
If Sydney does not receive a shower before Wednesday of next week, it will be the driest start to the month since 1882. Back in 1882, no rain was recorded until the 20th of the month.
