In the first half of the fortnight, Singapore and the surrounding region may experience dry and warm conditions, due to a mass of dry air moving eastward from the Indian Ocean over the equatorial Southeast Asian region.

On one or two days, the thundery showers could be widespread, and may extend into the early evening. In addition, island-wide thundery showers with occasional gusty winds, due to Sumatra squalls, can be expected in the predawn and morning on one or two days. The rainfall for the first fortnight of July 2022 is forecast to be below average over most parts of the island.
