September Weather Predictions
September in Japan promises a mix of sunshine and rain, with a high-pressure system gradually weakening throughout the week. A low-pressure system is expected to move east from China, bringing a front near eastern Japan on the 19th. By the 20th, this system will shift to the Sea of Okhotsk, pushing the front southward. This front will stay stationary over Japan from the 21st to the 23rd, leading to persistent weather patterns. Additionally, a tropical disturbance may move north from the Okinawa region, potentially bringing more moisture and active weather conditions near the front. Prepare for humid and rainy conditions, so pack light, breathable clothing along with a rain jacket or umbrella.
Typhoon Watch
While there are no typhoon warnings for mainland Japan this week, Typhoon Pulasan is expected to head towards Okinawa around September 19th. During typhoons, travel can be disrupted with delays and cancellations.
