Weather in Georgetown

Planning your day in Georgetown? Here you will find the most up-to-date information on weather conditions, as well as detailed forecasts and clear charts to help you plan the perfect holiday.

Georgetown, the capital of Guyana, is characterised by a tropical climate. This means the weather here is warm and humid throughout the year. Average annual temperatures fluctuate only slightly, remaining within a comfortable range of approximately 25°C to 28°C. You will not encounter sharp temperature changes, making trip planning quite predictable in this regard.

Instead of four distinct seasons, Georgetown has periods of varying rainfall intensity. Although it rains almost all year round, there are two wetter seasons: the main one is from May to July (peaking in June, when about 13 mm of precipitation falls and there are up to 30 rainy days), and a less pronounced one in November-December. Even in the "driest" months, such as September or February, the number of rainy days remains high (about 20-22 days), which is typical for an equatorial climate.

In general, be prepared for consistently warm weather with high humidity and frequent, but often short-lived, tropical downpours. Light clothing made from natural fabrics and an umbrella or raincoat will be useful at any time of the year. Despite the rain, the sun also frequently graces the city with its presence, creating a bright and vibrant atmosphere.

In Georgetown, you can expect typical tropical weather with minimal temperature fluctuations throughout the year. The average annual temperature stays within a very narrow and comfortable range. The "coolest" month is usually January with an average temperature of about 25.7°C, with daytime highs reaching 27.0°C and nighttime lows dropping to 24.4°C. The hottest period is considered to be September, when the average temperature rises to 27.9°C, with maximum daytime values around 29.8°C and nighttime lows around 26.0°C.

Since Georgetown is located in the tropics, there is no division into summer and winter in the European sense. Air temperature remains consistently high all year round. Even in the so-called "cool" months, such as January or February (average temperature 25.7°C - 25.9°C), the weather remains very warm, with daytime temperatures rarely dropping below 27°C. In the hottest months, such as August (average 27.2°C, max. 29.1°C), September (average 27.9°C, max. 29.8°C), and October (average 27.8°C, max. 29.5°C), the daytime heat can approach 30°C, which, combined with high humidity, creates a rather sultry feeling.

Notably, daily temperature fluctuations in Georgetown are small. The difference between daytime highs and nighttime lows is usually only about 2-4°C throughout the year. For example, in September, the maximum temperature is 29.8°C and the minimum is 26.0°C, resulting in a difference of 3.8°C. This means that nights here are also warm and do not bring significant coolness after the daytime heat. Thus, travellers should expect consistently warm, and at times hot, weather regardless of the month of their trip.

Precipitation in Georgetown is a phenomenon characteristic of the entire year, consistent with its humid tropical climate. The city does not have a clearly defined dry season, but the intensity of the rains undergoes noticeable fluctuations. Two main periods with increased rainfall are clearly traceable. The first, and most significant, rainy season covers the months from May to July. The second, somewhat less intense season falls within the period from November to December, and sometimes extends into January.

The greatest amount of precipitation falls in June, when the monthly average reaches 13 mm. Throughout the main rainy season, from May to July, it rains almost daily: the number of rainy days in each of these months is about 30. May is also characterised by a high level of precipitation (11 mm), as is July (10 mm). Rainfall at this time of year typically consists of heavy tropical downpours, which can be either short and sudden or more prolonged.

Relatively "dry" months in Georgetown include February, March, and September, when precipitation drops to 4 mm. September is also distinguished by the fewest number of rainy days – approximately 20. However, it is important to note that even during these periods, the rains do not stop completely, but merely become less abundant and frequent compared to the peak months. For instance, in October, 5 mm of precipitation falls across 21 rainy days, and in August – also 5 mm, but with 24 rainy days. November and December again bring an increase in precipitation to 8 mm and 9 mm respectively, with 26-28 rainy days, forming the second, less pronounced, wet season. Thus, being prepared for rain is relevant for travellers at any time of the year.

When packing for Georgetown, remember that a warm and humid tropical climate awaits you year-round. The basis of your wardrobe should consist of light, breathable items made from natural fabrics such as cotton or linen. Don't forget comfortable walking shoes, as exploring the city on foot is a pleasure. High SPF sunscreen, sunglasses, and a hat are also mandatory, as the sun in Guyana can be very active. A light long-sleeved shirt or a cover-up will come in handy for protection from the sun or for comfort in air-conditioned rooms, as the air temperature is consistently high, averaging between 25.7°C and 27.9°C throughout the year.

Given the high probability of precipitation throughout the year, especially during the periods from May to July and November to December, when the number of rainy days reaches its maximum (up to 30 days per month, for example, in May, June, and July, with peak rainfall up to 13 mm in June), a compact umbrella or a light raincoat will become your faithful companions. Although the air temperature remains comfortably warm, due to frequent rains and high humidity, clothes may take longer to dry, so consider taking several changes of clothes with you. Insect repellent will also be useful, especially for evening walks.
