Guyana has a tropical climate. The average annual temperature is 27°C, with maximum temperatures of 34°C not uncommon and minimum temperatures of 20°C. The humidity is about 88 percent in the morning and drops slightly to about 73 percent at noon. On the coast this quite high humidity is reduced by the constantly blowing sea winds.
There are two dry and two rainy periods. The long rainy season lasts from April to August. It is followed from September to November by a period of low rainfall. Then rainy weather comes up again, which usually lasts until the end of January. This short rainy period is followed by a shorter dry period, which usually lasts until April. In the south there is usually only one rainy season, which lasts from April to September.
The best travel time is generally at the end of the rainy season, i.e. end of January and end of August. From the temperature point of view, the period from October to mid-May is the most pleasant. For the interior of the country, trips should definitely take place during the dry season.
