December is in the hot, wet season with frequent thunderstorms and high humidity-travel can be affected by localized flooding. Tourist numbers fall and many lodges offer lower rates compared with the dry season.

Average temperature across Eswatini in December.
Mbabane - Malolotja
December in the Highveld is warm, humid and storm-prone; intense afternoon thunderstorms are the norm and they refresh the upland grasslands. Visitor numbers pick up around holiday periods and road travel can slow due to heavy rains and occasional stream overflow. Nights are warm enough to sleep without heavy blankets, but keep waterproofs and mosquito protection handy for both town and trail activities.
Manzini - Ezulwini Valley - Lobamba
December is hot, humid and storm-prone in the Middleveld, with powerful afternoon thunderstorms that recharge rivers and make for dramatic skies. The valley is lively with holiday traffic to Ezulwini and resorts, so expect crowded weekends and book ahead for popular lodges. Bring breathable clothes, waterproofs for daytime storms, and insect protection for evenings after rain.
Big Bend - Nsoko - Mlawula areas
December is hot, humid and active with thunderstorms in the Lowveld; the landscape is at its most luxuriant and lodges run full with holiday traffic. Strong afternoon storms refresh the bush but can strand vehicles and make some drives slow; river levels are high. Pack for heat and humidity, waterproofs, repellents, and accept that game-viewing itineraries may be adapted around weather and track conditions.
Hlane - Mlawula - Lubombo ridge
December is hot, humid and stormy, and the Lubombo foothills feel tropical; afternoon thunderstorms are frequent and can force early returns from bush walks. Lodges operate at full capacity for holiday travelers and game viewing by early morning or late afternoon remains the best strategy. Pack for heat, humidity, rain and insects and expect occasional logistical niggles when heavy rains affect access roads.
Incwala ceremonies may fall in December depending on the lunar cycle and include large public rituals tied to the monarchy.
