2. When will Israel be open to incoming visitors again?

At this moment there is not a known date in which Israel will be open to incoming visitors.

(It’s important to make sure you drink a lot, especially if you are walking, hiking or exercising during hot weather.)

Not at all. Israel is an entirely western country with an advanced level of hygiene, health care, diagnosis and medicine that is the envy of much of the world and on a par with the best of North America and Western Europe.

All visitors to Israel must hold a passport that is valid for at least six months from the date they are departing the country.  

Travellers with no nationality must hold a valid laissez-passer, as well as a visa back to the country that issued it.  Visitors are entitled to remain in Israel up to three months from the date of their arrival, in accordance with the conditions of the visa issued to them.  The State of Israel does not require a US or European passport holder to apply for a visa.

Most Israeli sockets are three-pronged but most also accept two-pronged plugs. Visitors who will use shavers, traveling irons and other small appliances may need transformers/ adaptor plugs. If your appliance does not work on 220 volts, you will need an adaptor.

What is the weather like in Israel, when is the best time to visit?

Israel is a year round destination that enjoys long, warm, dry summers and generally mild winters with somewhat drier, cooler weather in hilly regions, such as Jerusalem and Safed. Temperatures can vary widely so just pack for the "right" weather and you'll be fine. 

What kind of clothing should I pack?

In Summer, lightweight T-shirts, sleeveless shirts, shorts, and a bathing suit are recommended.

Pack a sweater or a jacket for nights in the mountains or the desert. In Winter, bring long sleeve shirts, sweaters and a scarf, gloves, a warm coat, and a raincoat and an umbrella.

Some religious sites require long pants for men and clothing that covers the shoulders and knees for women. ​
