Likely causes
Underwatering
Most likelyHow to tell: The leaves feel limp and the soil is dry several inches down. The plant usually perks up within a few hours of a deep soak.
What to do: Water the base of the plant deeply until water runs out of the drainage holes or saturates the surrounding soil. Ensure you are watering every 2 to 4 days during hot spells.
Heat Stress
PossibleHow to tell: The plant droops during the hottest part of the afternoon even if the soil is moist. It usually recovers once the sun goes down.
What to do: Apply a layer of organic mulch around the base to keep the roots cool. If the plant is in a container, move it to a spot with slight afternoon shade.

Stopping it coming back
Maintain a consistent watering schedule and use mulch to retain soil moisture during peak summer heat.
