Hi Liz, a few tips, dry season Indo = mainly surf season is supposedly Malaria free in Bali, I Would not without taking anti malarials as prescribed. Doxycycline is the one I use .
Lariam another can cause some pretty nasty side effects.
I almost died of malaria I had falciparum, the one that can cause brain fever.
Dengue fever, haven’t had but always follow as much mosquito avoidance precautions, which to me is always consider all Indo as mosquito territory. Surf wise head further east to Kuta Lombok, or west to Red Island Java. But crowds at more forgiving beaches are like mosquitos agiven

The further off the regular areas, the greater the disease risk
