Temperature (Below Zero)

This article is about Temperature in Subnautica. [[{{#explode:Temperature (Below Zero)|(}} (Below Zero)|Click here]] for information on this subject in Below Zero.

The temperature in Subnautica: Below Zero will be a major environmental game mechanic that the player must manage. Extreme temperatures (both hot and cold) are harmful to the player.

Temperatures and rate of exposure can be affected by the weather conditions. The current weather and forecast can be seen in a base Control Room.

Temperature Protection

Cold

Eating certain foods seems to boost warmth, as well as the use of Heating Gel. Thermal Lilies can be found on the surface and provide warmth to the player. Hot springs have also been mentioned.

A Cold Protection Suit exists to protect the player from low temperatures also.

Heat

The player starts taking damage from Temperatures above 50°C. The UI will indicate that the player is too hot by showing glowing orange lines on the edges of the screen. However, the player's thermal resistance increases to 70°C if they're wearing the Reinforced Dive Suit.

Energy Generation

High temperatures can be used to generate energy for Seabases through the Thermal Plant; because these are external generators that have to be placed at specific locations to work (any source above 25°C, which can be found in the HUD of the Prawn Suit or on the Thermal Plant), the Seabase needs to be close, or otherwise connected via Power Transmitters.

Prawn Suits can generate energy from heat using the Thermal Reactor upgrade (any source above 30°C).
