The climate of Rosignol

Rosignol, located at Guyana, sits directly beneath the Equatorial line. Being enclosed by the Amazon Rainforest on one side and Atlantic Ocean on the other, the Köppen Climate Classification describes it as an Af, indicating a Tropical Rainforest climate. Each month in Rosignol, it exhibits consistently high temperatures varying within a narrow range, from 27.2°C (81°F) to 28.8°C (83.8°F). With such high temperatures, the high level of evaporation stimulates an excessive amount of precipitation.

Among the predominant features of this climate are the lengthy daylight hours stretching from 11.8 to 12.5 hours. The steady number of daylight hours, unaffected by the discrete seasonality caused due to its equatorial position, progressively rise until the middle of the year and then smoothly descend towards December, a characteristic brought on by Earth's axial tilt. Throughout the year, the wide-ranging sea temperatures only fluctuate between 27.7°C (81.9°F) and 28.8°C (83.8°F).

The unique weather condition here is predicated on the brief semi-annual dry spells that can occur typically around February and August, influenced by the Inter-Tropical Convergence Zone (ITCZ). These irregular periods highlight the rare drops in an otherwise unanimously high rainfall throughout the year.

The best time to visit Rosignol

Taking into consideration the weather patterns, the optimal visiting period extends from May to July given that sea temperatures rise up to 28.2°C (82.8°F) to 28.8°C (83.8°F) and the daylight hours peak to 12.4 to 12.5 hours. Despite the uniform yearly precipitation, these months receive slightly less rainfall offering tourists a chance to explore the rich biodiversity unencumbered by torrential rains.

The worst time to visit Rosignol

Conversely, February and August mark the less favorable periods to plan a visit. As previously mentioned, these months can present an atypical weather pattern where rainfall decreases, creating dryer conditions.
