Costa Rica's Pacific year has two halves. From December to April the country dries out — the tourism board draws the line at mid-December and late April — and the rains return in May and stay to November, with July and August bringing the veranillo, a drier spell inside the wet that is strongest on the Nicoya and the north and faint on the southern Pacific, and September and October the wettest weeks. The Caribbean coast keeps its own calendar.
We call them what they are: the dry season and the rainy season. The tourism board markets the rains as the green season; the months are the same. Each route is designed once and run in both — the itinerary, the lodges and the price do not change. The weather, the rivers, the light, the wildlife and the company do, enough that we write each edition its own page.
Two of our dry-season editions begin in early December, when the rains are shutting down rather than gone: the mountain still green from seven months of water, the nights only beginning to turn cold. The gravel edition waits for late January, when the Nicoya has dried out. By February the ridges are at their driest and clearest.
