Brief Answer:
Most likely due to loss of electrolytes

Detailed Answer:
Hi
Thanks for choosing HCM for your query!

As you are saying that dizziness was there when you reached back after a walk in hot weather it can be because of electrolyte lost in sweating in hot conditions. Most likely due to loss of electrolytes you felt dizzy.

However dizziness is usually caused either due to
Heart-It could be presyncope
Nervous system- Decreased supply of blood to brain due to clogged carotid artery.
Internal ear-inner ear problem like vestibular neuritis.
Electrolyte disbalance-Most likely cause in your scenario.

Tests advised
Serum electrolyte
carotid artery doppler
Inner ear examination by e.n.t specialist

Thanks
