Is it true that the Government conducts cloud seeding to ensure that the haze does not affect F1?
This is not true. The Government has not been conducting cloud-seeding and has no plans to do so.

The National Environment Agency (NEA) is aware that there is an SMS rumour being circulated suggesting that the Government is conducting cloud-seeding to mitigate the impact of haze on F1, and that the resultant rain from this is harmful. These claims are untrue.
The Government has not been conducting cloud-seeding and has no plans to do so. Cloud seeding attempts to artificially induce rain by implanting clouds with suitable particles. However, there are no reliable means to validate the effectiveness of cloud seeding in Singapore. Cloud seeding also requires existing clouds as it cannot generate rain out of thin and dry air. During dry seasons, cloud seeding is less effective due to the lack of suitable clouds for seeding. The small size of Singapore and the variability of winds also mean that the induced rain, if any, may not fall directly over our island.
