May is a hot month with the average temperatures in the hot and humid 78°F (25.6°C) to 90°F (32.2°C). The climate is unvarying to differentiate the summer or winter seasons as the only difference is in the amount of rainfall, which averages about 6.7" (170.2mm) in the space of 14 rainy days.
Singapore is not exactly known for its beaches, but the sea temperatures at 85°F (29.4°C) are warm enough for swimming - of course, with adequate protection from the sun.

A cruise to neighboring countries like Malaysia and Thailand is a nice getaway from the heat and makes a memorable vacation. The hot weather does not dissuade the enthusiastic art lovers from a huge event in the form of the Singapore International Festival of Arts, which is a showcase of domestic and international talent. Evenings are suited for a walk down Orchard Road, the most significant commercial avenue with shopping malls hosting local brands and international retailers.
