Yes, the heat can give you a headache.

Dehydration: The heat can cause you to lose fluids more quickly. Dehydration can lead to several problems, including headaches.

Increased blood flow to the head: When you're hot, your blood vessels dilate to cool you down. This increase in blood flow to the head can also cause headaches.

Muscle tension: When you're hot, you may hold muscle tension in your neck and shoulders. This tension can lead to headaches.

Sunburn: If you're sunburned, the release of inflammatory chemicals may also cause headaches.
