7    The first half of August 2026 was mostly dry, with only a few days of brief showers over Singapore. These conditions were attributed to suppressed rain cloud formation caused by a dry air mass over Singapore and the surrounding region. Thundery showers affected parts of the island on a few days during this period. The highest rainfall recorded in the first half of August 2026 was a daily total of 39.2 mm, registered at Seraya Road on 2 August 2026 and Paya Lebar on 15 August 2026.

8    In the first half of August 2026, daily maximum temperatures exceeded 33 degrees Celsius on all but one day.

The nights were warm, with minimum night-time temperatures remaining above 27 degrees Celsius across many parts of the island.

9     Well-below-average rainfall was recorded across the island in the first half of August 2026. The highest anomaly of 100 per cent below-average was recorded at Changi.
