Small habits that make a visit to Managua smoother, from carrying small notes to planning around the midday heat.

Money
The local currency is the córdoba (NIO). In many visitor-facing places, United States dollars are also commonly accepted, but change is often given in córdobas. Carry small notes for taxis, markets and street food, because vendors may not have change for large ones. Cards are accepted in many shops, supermarkets and restaurants, less so in markets and small eateries. ATMs are found in shopping centres and banks; use them in daylight in busy, enclosed locations.
Heat and sun
Managua is hot. Drink plenty of water, wear a hat and sunscreen, and plan sightseeing for the cooler hours. Many locals rest in the middle of the day, and so should you. Air-conditioned shopping centres and cafés offer a break from the heat. Light, loose clothing in natural fabrics is far more comfortable than anything tight, and a small towel or handkerchief is a local habit for good reason.
Water and food
Most visitors drink bottled or purified water, which is widely available. Busy food stalls with fresh cooking are generally a good bet; see fritangas and refrescos. Wash or peel fruit.
Staying connected
Mobile coverage in the city is good, and local SIM cards are sold in shopping centres and phone shops. Many cafés, guesthouses and hotels offer Wi-Fi. Download an offline map before you arrive, since it makes landmark directions much easier.
Courtesy
Greetings matter: say "buenos días" or "buenas tardes" when entering a shop, taxi or office. Nicaraguans are generally warm and helpful; a little Spanish is appreciated (see Spanish for visitors). Dress modestly in churches, and ask before photographing people.
Keep things simple
As in any large city, keep valuables out of sight, carry only what you need for the day, and use taxis recommended by your accommodation at night. Check official sources from your own country before travelling for current entry and travel information; this guide does not cover formalities.
