Weather in August

August in Guyana is the final month of the major rainy season. As with the preceding months of this period, August is characterized by high levels of rainfall, often exceeding 250mm (9.84"). Regular showers continue to define the weather throughout the month, maintaining the consistently damp environment typical of this time of year.

Major cities such as Georgetown and New Amsterdam, as well as smaller towns like Linden, continue to experience these substantial downpours. Although the country's infrastructure is designed to manage such rainfall, the persistent and heavy showers can lead to localised flooding, particularly in lower-lying regions.

Despite the high levels of precipitation, August maintains the consistently warm temperatures characteristic of Guyana's tropical monsoon climate. Average temperatures range from 23°C (73.4°F) to 30°C (86°F), ensuring a steady level of warmth throughout the month. August does not record any extremes of temperature, instead contributing to the uniformity typical of Guyana's climate.

As August transitions into September, there is a significant change in the weather pattern. The heavy rainfall of the rainy season gives way to a drier spell, marking the end of the major rainy season. The transition from August to September thus signifies a shift from one of the wettest periods of the year to a notably drier phase.
