In the first half of the year, the peak season usually starts in mid February and continues till the end of May. It starts again in September and continues till the end of November. These are the times where the weather is at its best, but it is worth noting that weather patterns are inconsistent, so it is possible to have perfect weather throughout the year, as most regions record less than 30 days of rain per year. The summer is hot, but nowhere as hot as the gulf countries, so is perfectly bearable.
Absolutely, Jordan has a very low crime rate, and given that tourism is the main source of income for Jordan, security is excellent at all hotels and tourist sites.
Yes, it certainly is! Jordan has become one of the most popular choices for a family vacation in the Near East, as it boasts family-friendly hotels, resorts, sites and attractions for children of all ages.
Jordan issues a single entry visa to most travellers upon their arrival at the airport or at one of the shared crossing points with Israel, that is of course in case your nationality does not require a pre-issued visa and you plan to stay in Jordan for a minimum of 48 hours. To check if you need a pre-arranged visa or not, please check the list in the following link:
It does snow in the highlands, but it rarely snows for more than a couple of days a year, and most of the time, the snow is already gone within a day or two
You have to take into consideration that Jordan has different climatic zones, which are dependent on the latitude and altitude, so it is not easy to give an answer to that question. The Dead Sea (410 metres below Sea level), and Aqaba on the southern tip of Jordan by the red sea are relatively warm throughout the year, and can get very hot in the summer months of July and August. Nevertheless, all areas of Jordan have low humidity, so the heat is usually bearable even in the peak of summer. The western highlands, which span almost the whole length of the country are cooler in the summer, and can be pretty cold in winter, with occasional snowfall about once every other year in the northern peaks, Amman and around the Petra region, though the snow rarely settles for more than a day or two. Summer nights in the highlands are usually cool.
