September warms up but stays largely dry; this is a transitional month before the spring rains. Landscapes start to lose the deep winter browns, and wildlife viewing remains very good.

Average temperature across Eswatini in September.
Mbabane - Malolotja
September sees the first real push towards spring warmth; daytime temperatures rise and wildflowers begin showing on Malolotja slopes, making it a rewarding month for photographers. Afternoon thunderstorms are still rare but possible late in the month; the improvement in trails makes multi-day hikes easier. Prepare for variable weather - light rain gear and sun protection - and book accommodation early if visiting the Ezulwini Valley for cultural events.
Manzini - Ezulwini Valley - Lobamba
September brings warming by day and more humidity creeping in; late-month thunderstorms may begin to appear as the wet season approaches. The Reed Dance and other cultural events in Lobamba and Ezulwini draw visitors, so expect peak-day crowds and book accommodation early. Day trips to Mlilwane and Mantenga Falls are rewarding as paths green up, but carry a simple rain layer for sudden showers.
Big Bend - Nsoko - Mlawula areas
September warms noticeably as the dry season ends and the first pre-monsoon storms may appear late in the month; grass starts browning and dust increases on unpaved tracks. This transitional month provides excellent game viewing before the rains return and fewer mid-month visitors than peak dry-season periods. Carry a light dust mask if you are sensitive and be prepared for windier conditions on open safaris.
Hlane - Mlawula - Lubombo ridge
September warms noticeably as pre-monsoon humidity begins to rise; late-month showers can appear but are not yet frequent. Bird migration patterns bring additional species through Mlawula and adjacent reserves, pleasing birdwatchers seeking seasonal blooms. Bring insect repellent and a short rain shell for the odd storm, and book guided drives if you want reliable early-morning wildlife encounters.
There are no major festivals or events in Eswatini during September to be aware of.
