Drink plenty of water. April through August can be very hot up to 50 ÂºC and humid. Use an umbrella to protect you from the harsh sun. It is important to stay hydrated, especially if you are outdoors during the day. Bottled water is sold practically everywhere in the city from "Cold Stores" and small restaurants at very reasonable prices. In the souk, walking vendors offer small chilled bottles but you may end up paying more than the bottle is really worth. If you are living in Bahrain for an extended period of time, you can set up an arrangement for a neighborhood Cold Store to deliver bottled water to your flat, or sign up for water delivery through several companies on the island.
Bahrain is a fairly gracious host nation but it is imperative to demonstrate respect and courtesy in reference to their particular cultural practices and religion at all times. When out in places where local Arabs can be found it is advisable to wear long trousers, or shorts, and women shouldn't wear a see-through dress. However, in beach clubs and hotels, swimsuits, bikinis and shorts are okay to wear. Do not show signs of affection to members of the opposite sex in public. People of the opposite sex have been arrested for kissing in public and it is just not socially accepted. Always avoid any confrontation and never become involved in an argument, especially with a local.
