Weather conditions throughout the Singapore Grand Prix week will be predominately dictated by the presence of the SouthWest monsoon, according to UBIMET, official meteorological service provider to the FIA.
For the majority of the week the mornings will begin mostly dry and sunny with cloud building rapidly to thundery showers between late morning and early afternoon.
As is common in the tropics, these showers may be heavy at times accompanied with the hazard of strong rain and gusty winds. The highest temperatures will range from 30 to 34 degrees.
Evenings and nights will remain mostly dry with temperatures not below 25 degrees.
As the race, practice and qualifying sessions take place after sunset, the chance of dry weather conditions is high. However, thundery showers cannot be excluded completely.
