Honduras' Roatán delivers Caribbean dive resorts at a fraction of Cayman prices, Copán's intricately carved Mayan stelae rival Tikal, and the Mosquito Coast's rainforest covers 20,000 square kilometres.
Dry season on the Bay Islands with Roatán and Utila diving at peak visibility, and Copán's stelae carvings sharp in dry-season light.
Rainy afternoons in the interior, Bay Islands largely unaffected, and whale shark season around Utila peaks late February through April.
Hurricane season peaks September on the Caribbean coast. Bay Islands rates drop and inland Copán reliably accessible.
Hurricane risk fading, dry season returning, and Roatán's high season ramping up by mid-December for the Christmas holiday rush.
