Macau Weather in September: What to Expect for Temperature and Rainfall

September marks the transition from summer to early autumn in Macau, bringing a mix of warm days, high humidity, and the tail end of the rainy season. For international travelers planning a visit, here is a practical guide to the climate and how to prepare.

Temperature Overview

In September, Macau experiences average daytime highs of around 31°C (88°F) and nighttime lows near 26°C (79°F). The weather remains consistently warm and balmy, with high humidity levels often exceeding 80%. While the intense summer heat begins to ease slightly, you can still expect sultry conditions, especially in the afternoon.

• What to wear: Light, breathable fabrics such as cotton or linen. Shorts, t-shirts, sundresses, and sandals are suitable. Bring a light jacket or shawl for air-conditioned indoor spaces like casinos, malls, or museums.
• Sun protection: Sunscreen, a wide-brimmed hat, and sunglasses are essential, as UV levels can still be high.

Rainfall and Humidity

September is historically one of the wettest months in Macau. The city receives an average of about 200-250 mm (8-10 inches) of rain, spread over 12 to 15 rainy days. Showers are often heavy but tend to be short-lived, frequently occurring as afternoon thunderstorms or sudden downpours.

• Why so wet? Macau’s subtropical climate means September is still influenced by the southwest monsoon and occasional tropical cyclones (typhoons). While the peak typhoon season is August, September can still see stormy spells or increased cloud cover.
• What to bring: A compact umbrella or a lightweight waterproof jacket is a must. Waterproof shoes or sandals that can handle puddles will keep you comfortable.

Practical Travel Advice for September

• Embrace indoor attractions: Plan your day around the weather. Mornings are often clearer. Afternoons may bring rain – a perfect time to explore Macau’s UNESCO World Heritage sites, museums, casinos, or shopping malls. The Ruins of St. Paul’s, A-Ma Temple, and the Macau Museum are excellent indoor options.
• Stay flexible: If a heavy downpour hits, consider hopping into a local café for a Portuguese egg tart or waiting it out under a covered walkway. Showers usually pass within an hour.
• Monitor typhoon warnings: Check local weather forecasts before heading out. In case of a typhoon signal, most outdoor attractions and ferry services may be suspended. Always follow advice from local authorities and your hotel.
• Less crowded: September is part of the shoulder season between summer vacations and the National Day holiday. You’ll find shorter queues at major sights and more hotel availability compared to peak months.
