May weather forecast
Tema, Ghana

May’s weather ushers in the peak of the rainy season in Tema. A significant increase in rainfall could dampen outdoor activities. Despite the showers, temperatures remain relatively warm, similar to those in April. It is during this interval that the city records its highest rainfall, hitting an epic value of 68mm (2.68"). As June approaches, expect a continuation of similar weather conditions.

Temperature

As April turns into May, the average high-temperatures rest at a still hot 30.3°C (86.5°F), showing a minor variation from the prior month. During the month of May, Tema's average nighttime temperature closely mirrors its daytime counterpart, at a moderately hot 26.8°C (80.2°F).

Heat index

For most parts of May, the heat index is appraised at a torrid 38°C (100.4°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation. Warning! The Sun's UV rays intensify with reflections from sand and water.
