Although the Galapagos Islands are located in the Equator, but it has moderate, drier climate rather than typical tropical weather. This because of three confluent Ocean currents that determine the two yearly seasons in the Archipelago: cool/dry season from mid-June to early-December and the wet season from mid-December to early-June.
Average temperature range: 69°-84°F / 21°-30°C. Weather in Galapagos has variations on each season.
On a general basis, unless included on the given price for the confirmed cruise, passenger needs to bring enough cash on board to cover costs like Galapagos entrance fee ($100 p.p. in cash on arrival to Islands), mandatory Transit Control Card ($20 p.p. paid before check-in in cash), snorkeling equipment & wet suit rental (in cash on board), personal expenses, extras, soft & alcoholic drinks, tips for guide& crew and other expenses not specified in the itinerary.
Some Luxury and First accept Credit Card payments on board for on board consumption but Midrange and Economy require payments in cash only. It is imperative that you bring enough cash (U.S. Dollars) in all cases to cover your expenses while cruising the Galapagos.
