Question 1

What were the temperature extremes in Cairo in 2025?

Accepted Answer

Cairo swung between a scorching high of 46.1°C (115.0°F) and a chilly low of 4.0°C (39.2°F) in 2025, giving the Egyptian capital an annual temperature spread of roughly 42°C (76°F).

The hottest reading of the year arrived earlier than many expect: the 46.1°C (115.0°F) peak was recorded in May 2025, driven by the hot, dry spring winds that sweep in from the desert. The coldest moment came in February 2025, when temperatures dipped to 4.0°C (39.2°F) on the coolest nights.

Looking at full-month averages helps put these extremes in context:

- **Warmest month:** July 2025, averaging 30.1°C (86.2°F)
- **Coolest month:** February 2025, averaging 13.9°C (57.0°F)
- **Annual average:** 22.7°C (72.8°F) across all of 2025

These figures confirm Cairo's classic hot desert climate, where summer days are reliably intense and winters stay mild rather than truly cold. The wide gap between the May high and the February low shows how much the desert setting amplifies daily and seasonal swings, with hot afternoons often giving way to surprisingly cool nights.

For visitors, the takeaway is practical: pack light, breathable clothing and sun protection if you travel to Cairo between May and September, but bring a light jacket for the cooler winter mornings of December through February. The autumn and early-spring shoulder months offer the most comfortable balance of warmth without the peak-summer heat.

Question 2

How much rainfall does Cairo get in a year?

Accepted Answer

Cairo receives very little rainfall, totaling just **25.5 mm (1.0 inch)** across all of 2025 — confirming the city's hot desert climate where precipitation is rare year-round.

The small amount of rain that does fall in Cairo is concentrated in the cooler months. The wettest month of 2025 was December with 7.3 mm (0.29 in), closely followed by January with 7.1 mm (0.28 in). Spring added a little more, with 6.5 mm (0.26 in) in March and 4.1 mm (0.16 in) in May.

Cairo's summer is almost completely dry. Six months of 2025 recorded no measurable rainfall at all (April, June, July, August, September, and October), and the entire summer period from June to August saw 0.0 mm of rain. Across the whole year, only 7 days had any measurable precipitation.

This extreme dryness is typical for Cairo, which sits at just 54 m (177 ft) elevation in the arid Nile Valley. With a 2025 annual mean temperature of 22.7°C (72.9°F) and abundant sunshine, visitors can plan outdoor sightseeing with very little concern about rain in almost any month.

If you want to avoid even the slightest chance of a shower, the late spring through autumn window is the safest bet, while the rare wet days cluster around December and January. Either way, rainfall is never a major factor when visiting Cairo.

Question 3

Which months had the most sunshine in Cairo in 2025?

Accepted Answer

Cairo was sunniest in **July, May, and August 2025**, with July topping the list at 387.7 hours of sunshine — roughly 12.5 hours of sun per day across the month.

These three months were remarkably close, reflecting Cairo's intense summer and late-spring sunshine:

- **July 2025:** 387.7 hours (average daily high of 44.5°C / 112.1°F)
- **May 2025:** 385.8 hours (average daily high of 46.1°C / 115.0°F)
- **August 2025:** 385.3 hours (average daily high of 43.9°C / 111.0°F)

Across all of 2025, Cairo recorded a total of 3,728.8 sunshine hours, averaging about 10.2 hours of sunshine per day over the year. The summer months of June to August alone delivered 1,139.7 hours of sun. By contrast, February 2025 was the cloudiest month with just 205.9 hours, a typical winter low.

For visitors and residents, this means Cairo's peak sunshine arrives alongside its peak heat. While May through August offer the longest, brightest days, daytime highs frequently climbed above 43°C (109°F), so the abundant sunlight is best enjoyed early in the morning or later in the evening. If you want plenty of sun with more comfortable temperatures, the shoulder months of October (316.1 hours) and March (286.4 hours) still provide generous sunshine in Cairo without the extreme summer heat.

Question 4

What were the average summer temperatures in Cairo in 2025?

Accepted Answer

Cairo had an average summer temperature of 29.2°C (84.6°F) across the 2025 meteorological summer (June 1 to August 31), confirming its reputation as one of the hottest major cities in the region.

During these months, daytime highs in Cairo averaged a scorching 39.1°C (102.3°F), while nights cooled to a more comfortable average low of 19.6°C (67.3°F). This wide daily swing of nearly 20°C is typical of Cairo's desert climate, where dry air releases heat quickly after sunset. Average humidity stayed moderate at 48.5%, making the heat feel less oppressive than in coastal cities.

July was the hottest month of the season, with a mean temperature of 30.1°C (86.2°F) and average highs of 40.2°C (104.3°F). The single hottest day came on 27 July 2025, when the temperature peaked at 44.5°C (112.1°F). In total, Cairo recorded 31 days where the high reached 40°C (104°F) or above during summer 2025.

For travelers, these figures mean summer in Cairo demands serious heat precautions: sightseeing at the Pyramids or Egyptian Museum is best done in the early morning, with midday hours reserved for shade, water, and air-conditioned indoor stops. The drier evenings, however, make outdoor dining along the Nile genuinely pleasant once the sun goes down.

Question 5

How humid is Cairo throughout the year, and which months are most humid?

Accepted Answer

Cairo has a moderately dry climate, with an average relative humidity of about 53.7% across 2025. Humidity is highest in late autumn and winter and lowest in spring, but the city never becomes truly muggy.

The most humid month in Cairo during 2025 was December at 65.2%, closely followed by November at 64.2%. At the other extreme, May was the driest month with average humidity of just 40.8%, part of a dry spring (March–May) that averaged 44.7%.

Grouping the year into meteorological seasons highlights the pattern in Cairo:

- **Winter (January–February 2025):** 60.1% average humidity, the most humid season alongside autumn
- **Spring (March–May 2025):** 44.7%, the driest stretch of the year
- **Summer (June–August 2025):** 48.6%, kept moderate by hot, desert-influenced air
- **Autumn (September–November 2025):** 59.8%, rising steadily toward winter

Notably, Cairo's hottest months were not its most humid. Even as average temperatures peaked near 30.1°C (86.2°F) in July 2025, humidity stayed below 50%, so the heat feels dry rather than oppressive. Light winds averaging 9.9 km/h (6.2 mph) added gentle air movement throughout the year.

For visitors, this means Cairo's cooler winter months feel slightly damp but comfortable, while the warm season stays dry and breathable. Spring offers the lowest humidity in Cairo, ideal for sightseeing without the sticky discomfort common in more coastal climates.
