The best time to dive in the Red Sea is from March to May or September to November. However, the Red Sea can be dived by liveaboard year-round, and the best time to dive this Middle Eastern region is a matter of personal preference. December to February is the winter around the Red Sea. During these months, the water is quite cold, dipping to 72˚F (22˚C) in Egypt. Keep in mind that temperatures in Sudan are normally one or two degrees higher both above and below the water. However, during the winter months, you’ll have the best chance at spotting an oceanic whitetip shark in Egypt or hammerhead sharks in Sudan. December to February also boasts the best visibility in the Red Sea. Finally, the winter months represent the windy season, meaning that surface conditions may become quite rough, particularly in northern Egypt. March to May are the spring months in the Red Sea. At this time, the air and water temperatures are both moderately warm, offering a fantastic balance. This is also the best time to see a whale shark, particularly in the northern section of the Red Sea. However, March to May is high season for diving in the Red Sea, so expect some dive sites to be crowded. June to August are the low season for the Red Sea. Air temperatures reach uncomfortable levels for outside activity. But, the warmer temperatures force hammerhead sharks further north into Egyptian waters. June to September are the best months to swim with these predators in the north section of the Red Sea. The summer months are also your best bet for snagging great liveaboard deals. Finally, September to November is the autumn season in the Red Sea. Again, air and sea temperatures balance for comfort above and below the surface. These three months are also the best time to spot thresher sharks throughout Sudanese and Egyptian waters. The autumn is also the best time for manta rays in Sudan. Much like the spring months, liveaboards in the Red Sea can be crowded at this time.
