The high season in Tanzania generally refers to the period of the year when tourism is at its peak, and prices for accommodations and tours are typically higher. The high season is generally characterized by dry and sunny weather conditions, making it an ideal time for wildlife safaris and beach holidays.

In Tanzania, the high season typically occurs during the months of June to October, which coincides with the dry season. This is the best time for game viewing, as the dry weather conditions make it easier to spot wildlife gathering around water sources. Additionally, during the months of December to February, there is also a high season due to the festive holiday season and good weather conditions.

It's worth noting that the high season in Tanzania can vary depending on the specific destination within the country. For example, the peak season for climbing Mount Kilimanjaro is generally from June to October and December to February, while the peak season for beach holidays in Zanzibar is from December to February and June to September
