Spring arrives in Bobington the way it always does — sideways, with rain.

The Harbour Authority issued its annual March gales advisory on Sunday morning, a document that in ordinary years receives approximately as much public attention as the tide tables. This is not an ordinary year.

The advisory warns of a period of “sustained unsettled weather” across the Narrow Sea and the Cape of Sarenne passage beginning mid-week, with gale-force winds forecast for Thursday and Friday. For the fourteen cargo vessels currently rerouting around the Cape to avoid the closed Kaelmar Strait — adding twelve to fifteen days to their voyages — the advisory means rougher seas, longer transit times, and the possibility of shelter delays at Sarenne or the southern anchorages.

“The Cape in March is not a gentle passage,” said Harbour Master Cornelius Ashby, who has issued the advisory for thirteen consecutive years. “Ships that would normally transit the strait in two days may spend four or five days beating around the Cape in heavy weather. In a crisis that is already measured in weeks of supply, every extra day matters.”

The Spice Calculation

For the Spice Crisis Committee, which convenes its first meeting at Guild Hall tomorrow morning, the gales advisory adds a new variable to an already anxious arithmetic. The committee’s preliminary estimate of eight to ten weeks of supply at rationed levels assumes continued — if delayed — arrivals of eastern goods via the Sarenne route. Sustained storm disruption to that route could shorten the window considerably.

Wholesale broker Marta Engel, a committee member who tracks shipment schedules with professional exactitude, is understood to have at least two spice-carrying vessels on the Sarenne route at present. Their estimated arrival dates — previously mid-to-late March — may now slip into April if the gales persist.

The Eastern Spice Index, which eased to 347 on Friday, could reverse its modest decline if the weather compounds the diplomatic disruption.

The Ferry Factor

Closer to home, the advisory raises a more immediate question: what happens to the Ashwater ferry in high winds?

The Thornhill Star, which is scheduled to begin passenger crossings on Friday, operates on a sheltered river crossing of approximately 180 metres. But the Ashwater, swollen by March rains and subject to tidal influence in its lower reaches, can produce choppy conditions even between Thornhill Reach and Bramblegate Steps.

Gwen Alderly of Ashwater River Services said the vessel is rated for conditions well beyond anything the river typically produces. “The Star was built for coastal work,” she said. “A bit of chop on the Ashwater won’t trouble her. We have suspension protocols for genuinely severe weather, but I don’t expect to use them.”

The Harbour Authority’s advisory covers coastal and open-sea conditions; river services operate under a separate assessment framework. Nevertheless, the timing — a new ferry launching into the teeth of the first March gales — has a quality of narrative inevitability that the city has come to expect.

The Seasonal Pattern

March gales are a fixture of Bobington’s maritime calendar. The Harbour Authority has issued some form of spring storm advisory every year since 1911, when a March squall sank two coal barges in the lower harbour and prompted the first formal weather-warning protocol.

In most years, the advisory produces a week or two of disrupted schedules, a few delayed cargoes, and a brief spike in chandlers’ sales of foul-weather gear. But this year, with the Kaelmar Strait closed to commercial traffic, the Cape of Sarenne serving as the only viable eastern trade route, and the city’s spice and copper supplies measured in weeks rather than months, the spring storms carry consequences that the Harbour Authority’s measured language only partially conveys.

Ashby, whose office overlooks the harbour from a third-floor window on the Port Authority building, put it with characteristic brevity: “We cannot control the weather. We can control whether we are ready for it.”

The barometer, for the moment, is falling.
