The global congestion picture stayed calm for a fourth straight cycle — TPFS held at 27.2. But that flat headline hides a sharp divergence underneath: while more ports than ever sit in the LOW band, the worst-hit ports got dramatically worse. Casablanca and South Manila both absorbed delay increases of 40+ hours. Here’s the full read across 1,247 ports.
The Global Picture: 27.2 — Calm on Average, Concentrated at the Top
The Tradlinx Port Flow Score (TPFS) composite is 27.2 out of 100, essentially flat from 27.4. Global risk remains LOW for the fourth consecutive cycle.
LOW-rated ports rose to 868 (69.6% of all monitored ports, +8). But CONGESTED ports ticked up from 79 to 85 (+6), and the combined BUSY+CONGESTED share edged to 9.7% — marginally worse than the prior 9.4%. The story isn’t the count; it’s the severity at the ports that remained congested.
Average berth delay held at 7.0 hours. The extreme outlier is Conakry, Guinea at 342 hours (~14.3 days).
Regional Breakdown: Africa and South Asia Carry the Delay
The regional averages stayed moderate, but absolute delay times remain concentrated in a few regions.
West Africa (TPFS 43.8) again leads in average delay at 30.7 hours, with 30% of ports BUSY or CONGESTED. Conakry’s 342-hour outlier sits in this region.
East Africa & Indian Ocean (TPFS 41.9) follows at 21.0 hours average delay across its 30 monitored ports.
South Asia & Middle East (TPFS 38.0) holds 11.0 hours average delay with 19% of ports BUSY or CONGESTED.
Southeast Asia (TPFS 37.4) rose from 33.5, driven almost entirely by the Manila cluster’s deterioration. Average delay is 11.2 hours.
Northern Europe (TPFS 14.0) continued improving and stays Healthy, with Wilhelmshaven finally stabilizing after weeks of oscillation. North America (TPFS 9.6) remains the calmest region at 1.7 hours average delay.
Top Congested Ports: Casablanca and South Manila Surge
Casablanca surged 41 hours to 142.5 hours — its worst reading in this report’s history, reclaiming the #1 spot with 14 vessels waiting. After a brief easing last cycle, the backlog has returned with force.
South Manila posted the single biggest deterioration: a 56.3-hour jump to 132.4 hours, with 33 vessels waiting. Manila added 24.4 hours to reach 78.9 hours, and North Manila climbed to 48.0 hours with 33 vessels in queue. The entire Manila cluster is intensifying simultaneously.
Surabaya and Vado Ligure both escalated from STABLE to CONGESTED this cycle, at 43.2 and 24.8 hours respectively.
Koper held nearly flat at 36.6 hours (+0.2), finally pausing after three consecutive cycles of worsening followed by last cycle’s improvement.
Where Congestion Is Easing
Wilhelmshaven dropped from BUSY to STABLE (–10.2 hours), ending the stop-start pattern that ran across the prior three cycles.
Northern Europe led the improvements: Le Havre and Zeebrugge both moved to LOW, while Felixstowe dropped to LOW as well. Tianjin in Northeast Asia also improved from STABLE to LOW.
The pattern this cycle is clear: the broad base of ports is calm and improving, but a small set of persistent hotspots — Casablanca, the Manila cluster — is absorbing increasingly severe delays. Average congestion and worst-case congestion are moving in opposite directions.
