Jordan's only coastal city, and its complete opposite in feel from Amman or Petra — a slow, warm, port town where you can be diving a coral reef by mid-morning and eating grilled fish on the water by evening. The reef here is genuinely good, not a tourist add-on; visibility regularly exceeds 20 metres, and you can see Israel, Egypt, and Saudi Arabia from the same beach on a clear day, since all four countries meet at the head of the Gulf of Aqaba.
Aqaba is about 4 hours from Amman by road (330 km), an hour from Wadi Rum, and two hours from Petra — most people reach it as the last stop on a south-Jordan loop rather than a standalone trip. There's also a domestic airport (AQJ) if you'd rather fly down and skip the drive.
October to April is the comfortable window — daytime temperatures stay pleasant and the water is still warm enough to dive without a thick wetsuit. May to September gets seriously hot (mid-40s°C is normal), though the sea is at its warmest then if heat doesn't bother you.
If you're diving, book with a shop that supplies gear rather than bringing your own — checked baggage for dive kit adds up fast. The public beaches are decent but better reef access is through a dive centre or a beach club day-pass; ask your driver, since the good spots aren't always obvious from the road.
