Watch this month
This is a view of the archive, not a forecast. For each calendar month it lists the 73 recorded events that started in that month, the holiday periods theeffect method excludes from baselines, and the measured effect for events that have one. The archive is small and made of events we chose to record, so a count here is a count of records, not a probability that something will happen again. Built on 2026-10-30 (30 October 2026), showing October; data through 2026-10-25 (25 October 2026).

January: events recorded as starting in this month
1 of the 73 recorded events started in this month. That is too few to read as a pattern.
Severity range of these events: 3 (Significant), on the severity rubric.
Labour action: 1 event, severity 3
These are recorded events from the archive, not forecasts or probabilities. Other disruptions in other years may exist that we have not recorded.
January: calendar periods the effect method excludes
The effect method does not adjust for holidays. It leaves these days out of the baseline window, so a quiet or busy holiday week does not distort the comparison (effect method, section 4). If an event window itself overlaps one, the effect is still computed and the page says so.
| Period | Countries | Exclusion rule | Dates in the calendar |
|---|---|---|---|
| Lunar New Year | China, Hong Kong, Taiwan, South Korea, Singapore, Vietnam, Malaysia | 7 days before to 21 days after the first day |
|
| Christmas and New Year | every country | 24 December to 2 January | Every year, 24 December to 2 January. |

This is a measured change in public data during the event window, compared with a baseline before it. It shows timing, not cause. We describe an event as causing a change only when an official source says so.
November: seasonal pattern in our own records
None of the 15 recorded weather stoppages started in November. They started in February, June, July, August, September. That describes which months our records fall in; it does not say weather cannot disrupt freight in November.
Only our own event types and start months are used here. This is a view of the archive, not a forecast, and it adds no claim about climate or storm seasons beyond what the records show.
December: events recorded as starting in this month
3 of the 73 recorded events started in this month. The archive is small and these are recorded events, so the count says nothing about how likely one is next time.
Severity range of these events: 2 (Moderate) to 3 (Significant), on the severity rubric.
Labour action: 1 event, severity 3
Regulatory or customs action: 1 event, severity 2
Sanctions action: 1 event, severity 2
These are recorded events from the archive, not forecasts or probabilities. Other disruptions in other years may exist that we have not recorded.
December: calendar periods the effect method excludes
The effect method does not adjust for holidays. It leaves these days out of the baseline window, so a quiet or busy holiday week does not distort the comparison (effect method, section 4). If an event window itself overlaps one, the effect is still computed and the page says so.
| Period | Countries | Exclusion rule | Dates in the calendar |
|---|---|---|---|
| Christmas and New Year | every country | 24 December to 2 January | Every year, 24 December to 2 January. |
Lunar New Year and Eid move each year; Chuseok moves with the lunar calendar. Dates are the calendar's own table, not a forecast of anything else.
December: measured effects of events that started in this month
The lead measured effect per event: the current primary row with the largest absolute standardised score, as on closest calls. 2 of 3 events that started in December have one.
