In the eastern part of the country it rains more than in the west. There are three temperature zones in Nicaragua. In the lowlands (Pacific and Atlantic coast) temperatures vary roughly between 72Â° F at night and 86Â° F at daytime (22Â° C - 30Â° C). Temperature can reach 100Â° F in May (38Â° C).
Dark circles, or bags under your eyes, have many causes. These include: 1  Increased melanin (also called hyperpigmentation) also post-inflammatory hyperpigmentation due to allergies ('allergic shiners'). 2  Fat loss beneath the eye or shadowing due to skin laxity. 3  Broken blood vessels.
One of the big reasons bags and dark circles will form under your eyes relates to allergies. If your face feels full because of an allergy to pollen, mold, ragweed and so forth, there is a good chance the skin underneath your eyes will become inflamed.
