Accra lies just above the equator, and therefore enjoys a typical tropical climate. The only marked season is a rainy season. Temperatures in the country are constantly high, ranging from a low of 70°F (21°C) in the coolest month of August to a high of 100°F (38°C) or more in March. Humidity adds to the discomfort during the rainy season, which is in April, May, June, September and October in the north of the country, and is felt most in the months of April, May, June, September and October in the south. The harmattan, a dry desert wind, affects northern Ghana from December to March, lowering the humidity and creating hot days and cool nights. The harmattan is felt in the rest of the country in January. The best time to visit Ghana varies depending on desired activities and region but, generally speaking, the dry months between November and April are the best because they are slightly less hot and humid, the roads are in better shape, and there are fewer mosquitoes. During these months, the harmattan may blow but the wind helps reduce humidity which can be a relief.
