ecoregions: Windward Islands moist forests, Leeward Islands dry forests, Windward Islands dry forests, Windward Islands xeric scrub, and Lesser Antilles mangroves. The country had a 2019 Forest Landscape Integrity Index mean score of 6.17/10, ranking it 84th globally out of 172 countries. Climate Saint Lucia has a tropical climate, specifically a tropical rainforest climate (Af), moderated by northeast trade winds, with a dry season from 1 December to 31 May, and a wet/rainy season from 1 June to 30 November. Average daytime and nighttime temperatures are around , and respectively. Being fairly close to the equator, the island's temperature does not fluctuate much between winter and summer. Geology The geology of St. Lucia can be described as composing three main areas. The oldest, 16–18 Ma, volcanic rocks are exposed from Castries northward and consist of eroded basalt and andesite centres. The middle, central highlands, portion of the island consists of dissected andesite centres, 10.4 to 1 Mya, while the lower southwest portion of the island contains recent activity from the Soufriere Volcanic Centre (SVC). This SVC, centred about the Qualibou depression, contains pyroclastic flow deposits, lava flows, domes, block and ash flow deposits, and explosion craters. This depression's perimeter includes the town of Soufriere, Mount Tabac, Mt. Gimie, Morne Bonin, and Gros Piton. At in diameter, though the western portion is open towards the Grenada basin, the depression formed as recently as 100 kya. The depression is noted for its geothermal activity, especially at Sulphur Springs and Soufrière Estates, a phreatic eruption in 1776, and recent seismic activity (2000–2001). Eroded andesitic stratovolcanoes to the north east of the depression include Mt. Gimie, Piton St Esprit, and Mt. Grand Magazin, all greater than 1 Ma in age. Andesitic and dacite pyroclastic flows from these volcanoes are found at Morne Tabac dome (532 ka), Morne Bonin dome (273 kya), and Bellevue (264 kya). Avalanche deposits from the formation of the Qualibou depression are found offshore, and in the massive blocks of Rabot, Pleisance, and Coubaril. The dacitic domes of Petit Piton (109 kya) and Gros Piton (71 kya) were then extruded onto the depression floor accompanied by the Anse John (104 kya) and La Pointe (59.8 kya) pyroclastic flows. Later, pyroclastic flows include pumice-rich Belfond and Anse Noir (20 kya). Finally, the dacitic domes of Terre Blanche (15.3 kya) and Belfond (13.6 kya) formed within the depression.
