Hillsborough, Carriacou tide times

Hillsborough is the main town on Carriacou, the largest of the Grenadine islands within Grenada's territory, sitting 27 km north-northeast of Grenada main island. The town occupies a gently shelving bay on the island's west coast, facing the Grenadines channel toward Union Island (St. Vincent) to the north and sheltered from the dominant northeast trades by Carriacou's ridge. The ferry from Grenada docks at the Hillsborough jetty; the same jetty serves the inter-Grenadines trade that has defined this corridor since the pre-motorised era.

Carriacou is quieter, less developed, and more self-contained than Grenada main island in a way that is apparent immediately on arrival. The population is around 8,000; the economy is fishing, subsistence agriculture, and small-scale tourism. The boatbuilding tradition at Windward village on the northeast coast — where wooden sloops have been constructed by hand using techniques derived from Scottish settlers who arrived in the 17th century — is one of the most unusual cultural survivals in the Caribbean. The Carriacou Regatta in late July–early August, now in its sixth decade, is the island's major annual event: traditional wooden sloops, canots (small open racing boats), and modern dinghies race in the channel south of the island.

The tidal regime at Hillsborough is Caribbean microtidal: mixed semidiurnal, spring range 0.3–0.4 m. The Grenadines channel between Carriacou and Union Island has a moderate tidal current — 0.5–1.0 knots on spring tides — that runs broadly north-south through the channel. Sailing and motorboating in the channel, which is the standard transit route for the regional sailing circuit between Grenada and the Grenadines/St. Vincent, is not significantly affected by tidal state. The wind is the dominant variable.

Snorkelling around Hillsborough bay accesses the reef patches on the bay's southern and northern headlands. The Sandy Island (Carriacou) marine protected area, a small uninhabited cay 2 km northwest of Hillsborough, is the premier snorkel destination — ringed by a shallow reef in 1–4 m, with high fish density and hawksbill turtles feeding on the sandy approaches. Water transport from the Hillsborough jetty to Sandy Island takes 15 minutes by water taxi. The reef is best visited on the flood tide with calm sea conditions; the exposed northern exposure of the cay means swell from the northeast can make the water murky after sustained trade-wind days.

Anglers in Hillsborough work the bay edges and the channel between Carriacou and Petit Martinique (the small island 5 km to the northeast) for kingfish, carite, snapper, and flyingfish. The Grenadines channel current concentrates fish on the ebb at the headlands on both sides. Local pirogues fish the channel; visitors can arrange day charters through the Hillsborough jetty.

The Carriacou Museum on Patterson Street, immediately behind the main square, documents the island's history — the African origins of the population, the Scottish boatbuilders at Windward, the sugar plantation era, and the Carriacou Big Drum ceremony that survives as a living tradition of African spiritual practice adapted to the island's history. The museum is small but the context it provides for understanding why Carriacou has the character it does is worth the 45-minute visit before exploring the island further.

For beach families, Paradise Beach (1.5 km north of Hillsborough along the coast road) is the island's best swimming beach — shallow, calm, backed by palms, with the Saline Island and Frigate Island visible offshore. At low tide the shallow sand shelf extends 30–40 m from the waterline; children wade and play in water that rarely exceeds knee depth until 20 m from the beach edge. The calm and shallow character persists at all tide stages given the microtidal range.
