June weather forecast
Jeddah, Saudi Arabia

June marks the beginning of the hot desert summer for Jeddah, boasting higher temperatures and significant amounts of sunshine. The highest temperature for the year, a searing 38.3°C (100.9°F), is recorded this month, only to be surpassed in the following month of July. Despite the extensive heat, the city witnesses the highest amount of daylight hours in a year. As June ends, prepare for the peak of summer in July, bearing the highest recorded temperatures and elevated humidity levels.

Temperature

The arrival of June brings an average high-temperature of a still sweltering 38.3°C (100.9°F), closely following the temperature pattern of May. Jeddah records a significant temperature drop in June nights, lowering to an average of 24.8°C (76.6°F).

Heat index

The heat index value during June is estimated at a blazing hot 55°C (131°F). Warning: These weather conditions are classified as overly treacherous, heatstroke is approaching.
Take into consideration that the heat index values are calculated for shade and light wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In June, the average relative humidity is 58%.

Rainfall

Note: In June, a regular UV index of 12 translates into these guidelines:
Adopt every vital precaution, unprotected skin and eyes may burn rapidly. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Always opt for UVA and UVB-resistant sunglasses on radiant days. Broad-spectrum SPF 30+ sunscreen must be generously applied and reapplied every two hours or post any outdoor activity or swim. Take note! Sand and water reflections strengthen the Sun's UV exposure.
