Why It never rains on 9th of August in Singapore?

Every year,Singaporeans has a National Day Parade.Every year on the 9th of August,it doesn't rain.I wonder why it never rains on National Day?Is there something that is preventing rain to occur on 9th of August?There has got to be an explanation for this.

Well, I have a theory of my own.The Singapore government secretly has a weather controller machine that actually controls the weather.They used this machine to prevent heavy rains from happening on 9th of August.Or instead,they made it rain heavily before or after 9th of August so that 9th of August is dry.If they could not make it rain before or after 9th,they will try to make rain clouds rain early in the morning,mid day and late evening so it will not disrupt the parade.Now when it rains,it's not the drizzling type.It would be a quick heavy shower.Thats how they deplete the clouds of the rain water so there won't ever be a heavy shower.That's what I think.It's just too suspicious that it never rains on 9th of August in Singapore.I mean,it rains on Christmas,It rains on Hari Raya Puasa and Chinese new Year.On some holidays,it rains.Rain cna occur even on holidays.

This could have been a conspiracy which the government want to hide.If we can control the weather,shouldn't that be consider as a dangerous weapon?A machien that can control weather should be considered as a weapon of mass destruction just like in the game,RedAlert 2 where they have this weather control machine to destroy the enemies.

Anyways,Happy 41st National Day Singapore!!
