Wanderlust World Wanderlust World Madagascar, the world's fourth-largest island, lies in the Indian Ocean off southeastern Africa. Its geographic extent spans:
| Location | Coordinates | Significance |
|---|---|---|
| Antananarivo (Capital) | 18.8792°S, 47.5079°E | Central highlands, 1,280m elevation |
| Antsiranana (Diego Suarez) | 12.2667°S, 49.2833°E | Northern tip, world's 2nd largest natural bay |
| Toliara (Tuléar) | 23.3500°S, 43.6667°E | Southwest coast, spiny forest gateway |
| Tôlanaro (Fort Dauphin) | 25.0333°S, 46.9833°E | Southeastern tip, near Tropic of Capricorn |
| Nosy Be | 13.4000°S, 48.2667°E | Major offshore island, tourism hub |
Climate: Spanning 13° of latitude creates dramatic variation—tropical rainforest (northeast), tropical dry deciduous forest (west), spiny desert (southwest), and temperate highlands (center). The island straddles the Tropic of Capricorn (23.44°S), marking the southern boundary of the tropics.
Biodiversity: This latitudinal range, combined with 88 million years of isolation, produced Madagascar's staggering endemism: 90%+ of its 12,000+ plant species, all 100+ lemur species, and countless reptiles, amphibians, and invertebrates found nowhere else.
Time Zone: UTC+3 year-round (no DST). At 47°E, solar noon aligns closely with clock time.
Maritime Boundaries: The 43°-51°E span defines a vast Exclusive Economic Zone (EEZ) of ~1.2 million km², rich in tuna, shrimp, and potential seabed minerals.
For GPS/chart work: WGS84 datum. Nautical charts: BA 758 (North), BA 759 (East), BA 760 (South), BA 761 (West). Magnetic variation ~10-12°W (2024).
