Egypt Braces for continued Heatwave with High Humidity: Meteorological Authority Issues Forecast

Breaking: Egypt is set to experience another day of substantially high temperatures and humidity across most regions as the Meteorological Authority confirms a slight decrease in temperatures continues to impact the northern parts of the country, including Greater Cairo and Upper Egypt. The nation can expect hot to very hot and humid conditions throughout the day, with cooler, yet still humid, evenings and early mornings.

Dr. Mahmoud Shaheen, Director General of Predictions and Early Warning at the Meteorological Authority, highlighted that the elevated humidity levels will intensify the perceived heat. He stated that the actual feeling of the weather will exceed the recorded temperatures by 2 to 4 degrees celsius. This increased humidity is particularly notable from early morning hours in the northern areas, Greater Cairo, and Upper Egypt, possibly leading to thick fog on some routes connecting to the northern coastlines, western Cairo, and the Canal cities, including Central Sinai.

Moderate wind activity is anticipated along the Mediterranean coast, with speeds ranging between 30 to 45 km/h, causing wave heights to be between 1.5 to 2.25 meters. The Red Sea and the Gulf of Suez are expected to experience more significant wind activity, with speeds between 30 to 50 km/h, resulting in wave heights of 1.5 to 2.5 meters, which may disrupt marine navigation.Evergreen Insight: Understanding the impact of humidity on perceived temperature is crucial for public health and daily planning. High humidity reduces the body’s ability to cool itself through evaporation, making hot weather feel much more oppressive and potentially increasing the risk of heat-related illnesses. Staying hydrated and seeking cooler environments during the hottest parts of the day are essential, regardless of the specific temperature reading.

Today’s Forecasted Temperatures:

Cairo: Highs of 35°C, Lows of 25°C
Alexandria: Highs of 31°C, Lows of 22°C
Matrouh: Highs of 30°C, Lows of 23°C
Sohag: Highs of 40°C, Lows of 26°C
Qena: Highs of 42°C, Lows of 26°C
Aswan: Highs of 42°C, Lows of 28°C

Evergreen Insight: Temperature variations between coastal and inland areas, as well as between northern and southern Egypt, are a consistent feature of the country’s climate. Coastal regions often benefit from moderating sea breezes, while inland and southern areas, particularly Upper Egypt, typically experience more extreme heat. This pattern is influenced by geographical factors and prevailing atmospheric conditions,providing a valuable understanding of regional climate differences.

What is the relationship between air temperature, humidity, and the heat index, and why is the heat index a more accurate measure of how hot it feels?

Cairo Experiences Cooler Temperatures and Rising Heat Index

Understanding the Paradoxical Weather in Cairo, July 2025

Cairo, Egypt, is currently experiencing a engaging meteorological phenomenon: cooler temperatures coinciding with a rising heat index. While daily highs are registering lower than past averages for late July, the felt temperature – the heat index – is climbing. This is due to a significant increase in humidity levels. Understanding this difference is crucial for residents and visitors alike.This article breaks down the science behind it,potential health impacts,and how to stay safe during this unusual weather pattern. We’ll cover everything from Cairo weather updates to humidity effects and heat index risks.

The Science Behind Cooler Temperatures & Higher Heat Index

Typically, Cairo in July is synonymous with scorching heat. Though, this year, a shift in wind patterns has brought in more air from the Mediterranean Sea. This maritime air mass is cooler and, crucially, much more humid than the usual dry desert air.

Here’s a breakdown:

temperature vs. heat Index: Temperature measures how hot the air is. The heat index, also known as the “feels like” temperature, combines air temperature and relative humidity to determine how hot it feels to the human body.

Evaporative Cooling: In dry heat, our bodies cool down through sweat evaporation.However, high humidity hinders this process. When the air is already saturated with moisture,sweat doesn’t evaporate as efficiently,leaving us feeling hotter.

Current Conditions (July 20, 2025): Reports indicate daytime highs around 32-34°C (90-93°F). However, with humidity levels consistently above 60%, the heat index is soaring to 38-42°C (100-108°F) in some areas. This is a significant difference.

heat Exhaustion: Symptoms include heavy sweating, weakness, dizziness, headache, nausea, and muscle cramps.

Heat Stroke: A life-threatening condition characterized by a high body temperature (above 40°C/104°F), confusion, seizures, and loss of consciousness. Immediate medical attention is crucial.

Dehydration: Increased sweating leads to fluid loss. Insufficient hydration exacerbates the effects of heat stress.

Exacerbation of Existing Conditions: Individuals with pre-existing heart conditions, respiratory problems, or kidney disease are notably vulnerable.

Impact on vulnerable Populations: The elderly, young children, and outdoor workers are at higher risk.

Staying Safe: Practical Tips for Cairo Residents & visitors

Protecting yourself from the effects of a high heat index requires proactive measures.

1. Hydration is Key: Drink plenty of water throughout the day, even if you don’t feel thirsty. Avoid sugary drinks and alcohol, which can contribute to dehydration. Aim for at least 2-3 liters daily.
2. Seek Shade & Air Conditioning: Spend as much time as possible in air-conditioned environments. If air conditioning isn’t available, seek shade.
3. Dress Appropriately: Wear lightweight, loose-fitting, and light-colored clothing.
4. Limit Strenuous Activity: Avoid intense physical activity during the hottest parts of the day (typically between 11 am and 4 pm). If you must exercise, do so early in the morning or late in the evening.
5. Check on Vulnerable Individuals: Regularly check on elderly neighbors, family members, and friends to ensure they are staying cool and hydrated.
6. Recognize the Symptoms: Be aware of the signs of heat exhaustion and heat stroke, and seek medical attention immediately if you or someone you know experiences these symptoms.
7. Utilize Cairo’s Cooling Spaces: Many shopping malls and public libraries offer air-conditioned spaces for respite. Consider visiting these during peak heat hours.

Cairo’s Urban Heat island Effect & Humidity

Cairo, like many major cities, experiences an urban heat island effect. This means that urban areas are generally warmer than surrounding rural areas due to the concentration of buildings, pavement, and other surfaces that absorb and retain heat. The increased humidity is compounding this effect, making the city feel even hotter.

Building Materials: Concrete and asphalt absorb significant amounts of heat during the day and release it slowly at night.

Reduced Vegetation: Limited green spaces reduce evaporative cooling and contribute to higher temperatures.

* Air Pollution: Air pollution can trap heat and exacerbate the urban heat island effect.

Recent Observations & Local Responses (July 2025)

Local authorities in cairo have issued heat advisories and are encouraging residents to take precautions. Public service announcements are being broadcast on television and radio, emphasizing the importance of hydration and avoiding strenuous activity. Several hospitals have reported a slight increase in cases of heat exhaustion, but no widespread outbreaks have been reported.

Cairo’s design scene is also adapting.
