Determining when seasons begin and end in eSwatini has been tricky. Is it fall or winter right now?

In mid-May fall definitely began in Mbabane. It smelled like fall and the mornings were definitely chillier. The few trees that lose their leaves started dropping them.

Mbabane’s park has a few deciduous trees that now look like fall.

Now, the nights are colder with temps dropping below 50 degree F. Without snow or freezing temps, I wonder what the signal for winter is. Is it that I put all the blankets on my bed, am sleeping in layers of clothing, or that I started wearing two pairs of pants when I get home from work?
