May weather forecast
Accra, Ghana

May in Accra, Ghana marks the height of the rainy season. The month’s weather is a combination of dampness, high relative humidity, and amplified wind speeds. The amount of sunlight received diminishes slightly compared to the previous month. The downpours become excessively heavy with an average rainfall recorded at 66mm (2.6"). As May concludes, the residents expect the rainy conditions to slightly taper off moving into the next month.

Temperature

On the advent of May, Accra's average high-temperature exhibits a minor adjustment to a still tropical 30.7°C (87.3°F) from April's 31.4°C (88.5°F). During May, the nighttime temperatures in Accra align closely with the daytime averages, measuring a warm 26.3°C (79.3°F).

Heat index

May's average heat index is evaluated at a sweltering 39°C (102.2°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Consider that heat index readings are for situations in the shade and light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

The average relative humidity in May is 77%.

Note: The maximum UV index, 7 during May, leads to the following recommendations:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades. Be careful! The Sun's UV radiation is accentuated by reflecting off sand and water.
