August in Jamaica is expected to bring hot and humid conditions, with daytime temperatures generally around 30–33°C (86–91°F). The month falls within the island’s rainy season, so showers and thunderstorms are likely, often occurring in short, localized periods. Sea temperatures should remain around 29–30°C (84–86°F). August is also within the Atlantic hurricane season, so tropical weather systems remain a possibility, although the 2026 season outlook indicates a lower-than-normal level of activity.
