A regional perspective. A clearer plan for your shipment.
Typhoon activity and severe weather across East and Southeast Asia may affect vessel schedules, port operations, transshipment connections and equipment availability throughout September.
September is historically one of the most active periods for tropical cyclone development in the Western North Pacific and South China Sea.
Although not every port is directly affected by tropical cyclones, port closures, vessel displacement and congestion at one location may create downstream delays across subsequent vessel rotations.
Expect increased risk of schedule changes, port omissions, cargo rollover and revised ETD / ETA during this period.
Historical indicators based on publicly available PAGASA and Japan Meteorological Agency climatology. Historical patterns are not a forecast.
Average monthly named cyclones · JMA, 1991–2020
September sits within the historical peak period for tropical cyclone activity in the Western North Pacific. This increases the probability of port closures, vessel diversions, berth congestion and disrupted vessel rotations.

Annual bars are placeholders, not observed cyclone counts. The dashed reference is the verified JMA September average of 5.0 (1991–2020). Replace the annual series before publication.
Weather exposure and shipping disruption are different risks. A clear local port can still experience delayed inbound vessels and missed connections. These ratings are planning scenarios, not verified current port conditions. The ports below are a non-exhaustive watchlist for potential disruption, not confirmed affected ports or closure notices. Check your terminal and carrier advisory for the specific sailing.
Potential disruption channels to monitor. No carrier or terminal incidents have been confirmed in this template.
A shipment does not need to pass directly through the affected weather area to experience delays. Container shipping operates on interconnected vessel rotations, and disruption at one port may affect later calls across the network.
Customers are advised to allow additional schedule buffer during September, particularly for time-sensitive shipments.
Vessel ETD and ETA remain estimates and may be revised at short notice due to weather conditions, port closures, congestion, vessel schedule recovery or carrier operational decisions.
Where HaioConnect receives material schedule changes from carriers or operational partners, affected customers will be updated accordingly.
Weather events, port closures, vessel diversions, omissions and carrier schedule adjustments remain outside the direct control of HaioConnect.
Where shipment timing is critical, customers should avoid planning production, delivery or contractual commitments solely around the published vessel ETA.

JMA counts systems reaching tropical storm intensity or higher in the Western North Pacific and South China Sea. The ~18.6 cumulative indicator is the sum of rounded January–September monthly normals. PAGASA indicators cover the Philippine Area of Responsibility; these geographical scopes differ.
