Practicality of creating a overcast cloudy look in summer

Hi everyone. Im a cinematography student from SRFTI Kolkata, India. Im supposed to shoot a short film in June where i would have preferred to create an overcast look, but it will be summer here in India with occasional rain. Is there any way i can create an overcast look in camera, what are the limitations and challenges ill be facing if i go with this approach. please share your thoughts. Thanks in advance
