Singapore weather is shifting into a wetter rhythm as August begins. According to the Meteorological Service Singapore (MSS), residents can expect frequent thundery showers throughout the first half of the month—making it noticeably wetter than the final weeks of July.

Thanks to ongoing Southwest Monsoon conditions, winds from the southeast and southwest are pushing in late-morning and afternoon thunderstorms across the island. On some days, Sumatra squalls could also roll in during the pre-dawn or early morning hours, triggering widespread rain and strong winds just as many start their day.

Most areas will experience above-average rainfall, so expect August mornings to start damp and cloudy. Despite the increase in rain, daily highs will still range between 32°C and 34°C, with evenings remaining warm and humid, hovering in the upper 20s.

What It Means for Daily Life in Singapore

If you’re commuting, running errands, or planning outings, it’s worth noting how Singapore weather could affect your schedule. While thunderstorms may be short-lived, the intensity of the downpours, especially those linked to Sumatra squalls, can cause traffic slowdowns and delay outdoor activities.

Stay Dry and Ready

• Keep an umbrella or light raincoat with you—especially if you’re out between late morning and evening.
• Use the myENV app or check updates from MSS and NEA for lightning alerts and real-time forecasts.
• Plan outdoor activities in the early morning or late evening when rain chances are lower.

Early August 2025 brings a stormier stretch of Singapore weather, marked by daily afternoon showers and the occasional early morning squall. With above-average rainfall expected, it’s best to stay one step ahead of the skies. Whether you’re heading to work, school, or just out for coffee—be weather-aware, dress smart, and plan around the downpours.
