The wet, warm weather persists into August as the rainy season rudiments its phase of abatement. This monthly transition is marked by a noteworthy increase in the average high temperature. In spite of the prevailing rain, August enjoys an increase in sunshine hours, while wind speeds drop compared to July. Consequently, this month provides an ideal mix of refreshing rain showers and ample sunshine. August experiences an all-time high in rainfall, escalating to 110mm (4.33") over 22.2 days.

Temperature

The onset of August marks an average high-temperature of a still moderately hot 29.7°C (85.5°F), hardly differing from July's 29.1°C (84.4°F). Nighttime temperature in Arima reflects an average dip to a still moderately hot 26.1°C (79°F) in August, subtly cooler than its daytime highs.

Heat index

The heat index for August is calculated to be a torrid 36°C (96.8°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Heat index details are generally centered around shaded locations and a mild breeze. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
