February is another good month, on average, to grow grass in Bangkok, Chennai, Colombo, and Mumbai. Why? With average temperatures more than 25°C and sunshine well above 200 hours for the month, the growth of warm-season grasses can easily be controlled by turfgrass managers through adjustments in the amount of water and nitrogen applied. 

Hainan Island is sometimes referred to as the "Hawaii" of China, but Sanya is considerably cooler and has a lot less sunshine than does Honolulu in February. For about six months of the year, Sanya is a lot more like Hilo than Honolulu, and that means slightly cooler temperatures and significantly less sunshine.
