PortWatch: Daily Port Activity and Shipment Estimates for China

PortWatch provides daily port call counts and shipment volume estimates in metric tons for maritime hubs in China and Hong Kong SAR. This time-series dataset tracks logistics activity through March 2026 to monitor regional trade dynamics.

Use Cases

• Analyzing daily fluctuations in maritime traffic using port call counts
• Estimating regional trade throughput using incoming and outgoing shipment volumes in metric tons
• Detecting supply chain disruptions by monitoring daily deviations in port activity levels

Strengths

• Daily temporal resolution for high-frequency analysis
• Dual metrics covering both vessel frequency and cargo weight in metric tons
• Specific geographic focus on the China and Hong Kong SAR maritime corridor

Limitations

• Shipment volumes are derived estimates rather than direct sensor or customs data
• Metadata does not specify the number of individual ports included in the aggregate
