Remember that summers are very hot, particularly in the inland areas. You may still need a sweater or light jacket if seaside or in the mountain regions.
Break out the sassy sundresses and bright colors for your trip, as fashion and style are are paid attention to in the major cities. Women might consider printed skirts and halter tops in lightweight materials. Men might opt for cotton or linen shorts, as well as short-sleeved button-down shirts and printed T-shirts.
Bring comfortable walking shoes for touring the sites. Women might include wedge slip-on sandals and heels for evenings out. Men will impress in leather sandals or leather slip-on shoes.
Remember a sun hat, sunglasses and sunscreen.
Pack longer skirts and pants to wear for visiting churches, as you may not be allowed to enter in shorts.
Prepare for mild to cool winter temperatures. Long pants, sweaters and a jacket are must-haves.
Pack an umbrella if your plans include travel in early November to late February, when showers are likely.
