The Best Time to Visit Egypt's Red Sea for Diving, Month by Month
Ask ten divers when the best time to visit the Red Sea is, and you'll probably get ten different answers, and most of them will be right. The truth is that diving in Hurghada and the wider Red Sea is good almost year-round, which is part of why it's such a popular destination in the first place. What changes from month to month isn't whether you can dive, it's what kind of dive you're going to get: warmer or cooler water, better or slightly reduced visibility, and quieter or busier boats. Here's how the seasons actually break down.
Winter (December to February): Cool, Clear, and Quiet
Winter brings the coolest water of the year, typically around 22 to 24°C, with air temperatures between 18 and 24°C. A proper wetsuit, 5mm or thicker, is worth packing. In exchange for the slightly cooler water, you get some of the best visibility of the year, often 20 to 30 metres, and noticeably smaller groups on the boats. This is a good window for divers who care more about having a site to themselves than about diving in the warmest possible water. Macro life tends to be excellent, with stingrays and batfish showing up reliably around sites like Abu Galawa.
Spring (March to May): The Reef Wakes Up
As water temperature climbs into the mid-20s, spring becomes a season of activity on the reef. Triggerfish begin building nests, particularly around sites like Gota Abu Ramada, and schooling fish and filter feeders become more active as the water warms. Visibility is generally very good, in the 15 to 25 metre range, though it can drop briefly during coral spawning events. Air temperatures are comfortable, usually between 22 and 30°C, making this a pleasant season both in and out of the water.
Summer (June to August): Warm Water, Busier Boats
Summer is when the Red Sea gets genuinely warm, with water temperatures reaching 27 to 30°C, warm enough that many experienced divers are comfortable in just a 3mm suit or even a rash guard. Air temperatures climb steeply too, often 30 to 38°C, so the heat on the surface is a bigger factor than the heat in the water. This is peak season for visiting divers, so expect larger groups on boats and busier dive sites. It's also when advanced open water courses in Hurghada are in high demand, since many divers use the warm water and long daylight hours to push their certifications forward.
Autumn (September to November): The Sweet Spot
Autumn is where a lot of regular visitors land as their favourite season, and it's easy to see why. Water temperature stays warm at 26 to 28°C while air temperatures ease down to a more comfortable 26 to 34°C. Visibility rebounds to 20 to 30 metres, and crowds thin out noticeably from mid-October onward as the summer rush fades. Dolphins are more frequently reported near reefs like Fanous East and West during this period, and reef fish tend to be especially active as they build up activity before winter. If you want warm water without a packed boat, this is usually the window to target.
So, What's Actually "Best"?
It depends entirely on what you're optimizing for. Chasing the warmest possible water points you toward summer. Chasing the clearest water and smallest crowds points toward winter. Wanting both warm water and a quieter boat points squarely at autumn, which is why so many seasoned Red Sea divers quietly favour September through November. Spring is a strong middle ground if your travel dates are flexible and you want decent conditions without extreme heat or cold.
A Few Practical Notes
Whichever season you choose, a few things stay constant. Marine life in Hurghada is present throughout the year, so no season leaves you with an empty reef, though certain sightings do cluster around particular months. Equipment needs shift more than almost anything else between seasons, so check expected water temperature before you pack, rather than assuming last year's trip tells you what to bring this time. And if you're planning to combine a holiday with a first dive course in Hurghada, any season works, but the calmer, less crowded shoulder months of spring and autumn tend to make the learning process a little more relaxed.
Pick Your Season, Not Just Your Dates
The Red Sea doesn't really have a bad time to visit, which is unusual for a dive destination and a big part of its appeal. What it has instead is a set of trade-offs: warmth versus crowds, clarity versus cost, activity versus quiet. Once you know which of those matters most to you, picking a month becomes a lot easier than it looks from the outside.
