Egypt in summer: who it suits and who it destroys

We could tell you that summer in Egypt is wonderful and that you should book immediately. Instead here is the version that will actually make your holiday work: summer is excellent for one kind of trip, tolerable for a second, and a genuinely bad idea for a third. Knowing which one you are booking is the whole thing.

What the numbers actually mean

July and August in Luxor and Aswan regularly go past 40 °C, and in a bad week considerably past it. On the Red Sea coast — Hurghada, Makadi, El Gouna, Marsa Alam — the daytime figure is a few degrees lower and there is almost always a breeze off the water.

But the number is not the story. Two things change how it lands:

• Inland heat is dry. 42 °C in Luxor is a furnace, but sweat evaporates instantly and shade helps enormously. It is survivable in a way that the same figure in a humid climate is not — and it is why the early-start rule exists rather than being advice people ignore.
• Coastal heat is humid, and the sea does the work. Hurghada in August sits in the mid-to-high thirties with sea air, which most people find manageable, because you are never more than a minute from water.

And the thing nobody mentions in the brochures: the sea is at its best. The Red Sea reaches roughly 28–30 °C in late summer. You can stay in for hours without cooling down, which for snorkelling and diving is a real, measurable advantage over the winter, when a shortie wetsuit stops being optional.

Who summer genuinely suits

Beach and reef holidays. This is the honest case for summer, and it is a strong one. The water is at its warmest all year, the visibility is excellent, and a day that runs swim–shade–swim–shade barely notices the air temperature. If your plan is a Red Sea resort with snorkelling and boat days, summer is not a compromise — it is arguably the best time to do it.

Divers. Same reasoning, more so. Long dives in warm water, minimal exposure protection, and the northern wrecks and reefs at their most comfortable.

Anyone travelling on a budget. Summer is low season inland for obvious reasons, which means Luxor and Aswan hotels are at their cheapest of the year, Nile cruises are easier to get, and the sites that are shoulder-to-shoulder in January are nearly empty.

People who genuinely like heat. They exist, and they get an emptier, cheaper Egypt. There is no reason to talk them out of it.

Who should not book a summer trip

This is the part that matters more, and we would rather say it now than hear it afterwards.

• Anyone whose main goal is temples and tombs. A full Luxor west-bank day in August is genuinely punishing. The Valley of the Kings is a rock bowl that concentrates heat, the tombs are unventilated and hotter inside than out, and by ten in the morning you will be making decisions about what to skip. You can do it — with a 4 am start and discipline — but you will not enjoy it the way you would in November.
• Anyone with a heart or circulatory condition, or on medication affecting heat tolerance. Speak to your doctor rather than to us. This is not a formality.
• Families with toddlers or babies. Small children do not regulate temperature well and cannot tell you early enough that they are in trouble. A coastal resort with shade and a pool is fine; a day trip inland is not.
• Anyone on a tight, packed itinerary. Summer punishes over-scheduling more than any other factor. A trip with a long inland excursion on consecutive days will not work.
• People who wilt. If you already know you are miserable above 30 °C, you will be miserable here, and no amount of planning fixes that. Come in November.
