How hot will it be? That depends on the type of yoga you're doing.
Before trying a hot class, or any yoga class for that matter, it's a good idea to check with your healthcare provider to make sure that it's an appropriate activity for you. And make sure to drink water before and during hot classes! Here is a heat index for six of the most popular hot styles.
Bikram temperatures are slated to be heated to 105 F and 40% humidity. Bikram yoga is a trademarked class with 26-poses that are always done in the same order. After some bad press on the founder of Bikram, many studios removed the name Bikram and just call it a hot yoga studio. But they will also turn up the heat to around 105.
CorePower Yoga 2 (C2) class, which is their all-levels hot flow class, is taught in a room maintained between 93 and 98 F. They offer sculpt classes, hot yoga (like Bikram) 105 F room, C1, and C3 classes. Along with bikram at these temperature, a towel is needed over you mat or ideally a yoga rug, that will not move under your feet during practice.
Located in the U.S., South America, and Australia, with additional affiliates in Europe and Asia. Co-founder and former Bikram instructor, Mark Drost takes the Bikram sequence under the moniker Primary Hot Series. Classes are the same at 105 F. They also offer classes that range in temperature from 75 to 90 F.
Moksha Yoga/Modo Yoga
This Canadian-based yoga franchise with locations in eight U.S. states (and counting) keeps their "green" classrooms at 103 F. 40 pose sequece, which takes about 90 minutes. A shorter, condensed 60 or 75-minute version of the sequence or a vinyasa.
Yoga to the People
Yoga to the People studios has Traditional Hot Yoga classes at 105-108 F.
Yoga Rug instead of a Towel
Best suited is the new in increasingly popular ridgeback yoga rug which is superior to the ubiquitous yoga towel. To be used over a mat for these classes is essential for absorption, and known for never moving while practicing.
