I have got drenched at several previous occasions at this always excellent event.
But this year I and thousands of other revellers were treated to some lovely late August sunshine.
And the warm weather meant that festival staple - sitting on the grass - was actually an option this year.
From my sedentary position I massively enjoyed watching Sven Vath's atmospheric techno set from the Amnesia tent, and again checked out Paul Kalkbrenner from the humble floor of Clapham Common.
But I had to get to my feet for Sasha and Carl Cox, who were playing in the ANTS tent and on the main stage respectively.
Sasha took the aural soundscape to new levels and they were complemented by amazing red lighting in contrast to the usual monochrome atmosphere of the ANTS colony.
Cox's top-notch techno was a treat to behold with rolling percussing and his "oh yes, oh yes" mantra ringing out across the Common.
There was also time to check out trance legends Above & Beyond and progressive house head honcho John Digweed at the varied Sunday leg of the long-running weekender.
He finished with Egyptian Empire's classic ' The Horn Track' as darkness fell and planes flew overhead.
Next up was the finale, with The Chemical Brothers providing a storming headline set.
Beginning with 'Hey Boy, Hey Girl' was brave as it is probably their biggest track, but the sheer strength of the Chems' repertoire meant the crowd was kept moving throughout.
A superb light show also punctuated the electronic experience.
SW4 remains a potent part of the capital's festival scene - come rain or shine.
