Sydney, New South Wales.
Just after 1pm - at 13h03 by my timepiece - there was a large and resounding clap of thunder in the not-very-cloudy skies above the Botanic Gardens in Sydney.
Within a very few moments, the sky was clouded over with more ominous clouds.
After just ten minutes - by which time I was happily seated at the Sidewalk cafe under the Sydney Opera House, sipping coffee and eating a salad with prawns - the rain came down heavily and dramatically.
But this is a sunny land, and 'though the rain put on a brave face, and stuck it out for nearly an hour in fits and starts, well before 15h30, there was more than enough blue sky to make a sailor's uniform.
