Latvia is a country located in Northern Europe, and diving is not a popular activity there due to the cold water temperatures of the Baltic Sea. The water temperature in the Baltic Sea ranges from 7-22°C (45-72°F) throughout the year, making it too cold for most people to comfortably dive in without a drysuit.
If you are interested in diving in Latvia, the best time to visit would be during the summer months of June to August, when the water is at its warmest. However, even during the summer, the water is still quite cold, and a drysuit is recommended for all diving.
In general, the best time to visit Latvia for other activities, such as cultural tourism and outdoor adventures, will depend on your personal preferences and the specific regions of the country you plan to visit. Latvia has a temperate climate, and temperatures can vary significantly depending on the region and the time of year.
In general, the summer months of June to August are the most popular time to visit Latvia, with long days, warm temperatures, and a range of outdoor activities available. The spring and autumn months can also be pleasant, with cooler temperatures and fewer crowds. The winter months can be cold and snowy, with shorter days and limited daylight, but they offer the chance to experience the country’s winter sports and festivals.
