11 Weather and Environment
22  
33 Grand Theft Auto VI's Florida-inspired setting features dynamic weather and environmental systems visible across both official trailers. The game runs on an upgraded version of Rockstar's RAGE engine, which renders weather effects, water physics, and atmospheric lighting with significantly more detail than previous entries. Take-Two CEO Strauss Zelnick confirmed during an earnings call that the game world is entirely handcrafted, "building by building, street by street, neighborhood by neighborhood," with no generative AI involved in world building.

55 Rain and Storms
66  
77 Rain appears in multiple trailer scenes, most prominently in a Trailer 1 sequence showing a heavy downpour on a Florida-style highway. Palm trees stand partially submerged as temporary lakes form beside the freeway. Water pools in low spots and collects against barriers rather than spreading evenly across pavement, suggesting a dynamic water accumulation system rather than a simple visual overlay.

910 Road textures change from dry to wet during rainfall, altering how light interacts with the ground surface. Vehicle tires leave visible spray when driving through standing water. Night rain in Vice City produces particularly detailed reflections off neon signs and building facades.
1011  
1112 An in-game news ticker visible in Trailer 1 reads: "Leonida man sucked up in waterspout demands the city buy him a new suit," confirming that waterspouts exist at minimum as a narrative element in the world. Flood gauges (black-and-white striped poles with numerical markings) are also visible in trailer footage, suggesting a modeled flooding system.
1213  
1314 Fog and Atmospheric Haze
1415  
1516 The Grassrivers swamp region shows dense fog and atmospheric haze effects. Low-lying mist sits over the water in dawn and dusk scenes, creating a thick, humid atmosphere consistent with the Everglades-inspired environment. Mangroves line the waterways, and airboats are the primary vehicle for traversing the flooded grasslands. Flamingos take off in droves from the marshland, and alligators appear throughout the wetlands and even in residential areas like swimming pools and gas stations.

1718 Day-Night Cycle
1819  
1920 A full day-night cycle is confirmed through trailer footage showing sunrise, midday, golden hour, sunset, dusk, and nighttime. The exact duration of the in-game cycle has not been officially confirmed. GTA V used a 48-minute real-time cycle for one in-game day.
2021  
2122 Vice City transforms at night. Rockstar describes it as a place where "when the sun fades and the neon glows, everyone has something to gain, and more to lose." Neon signs, club lighting, police sirens, helicopter spotlights, and vehicle headlights create a completely different visual feel from the sun-drenched daytime. Light sources interact with wet surfaces, glass, and other reflective materials in real time.
2223  
2324 Lighting Technology
2425  
2526 Digital Foundry's analysis of Trailer 2 identified the entire lighting pipeline as being based on Ray-Traced Global Illumination (RTGI), with no rasterized lighting. This means light bounces off surfaces naturally, allowing interiors to be lit by outdoor light spilling through windows and doorways rather than relying on baked or pre-calculated lighting.

2729 Volumetric clouds received a noticeable upgrade between Trailer 1 and Trailer 2. The clouds became softer and more consistent with typical South Florida midday skies, with improved denoising applied to sky rendering. Ray-traced reflections are visible on rivers and smaller bodies of water, while screen-space reflections handle larger ocean surfaces, glass, and plastic materials.
2830  
2931 Specific lighting details visible in trailers include: grid-pattern shadows cast on Lucia's prison jumpsuit through bars, purple light bathing a dance floor, sunlight reflecting off character skin with subsurface scattering, and lens flares during sunset scenes on the coast.

3133 Water Physics
3234  
3335 Water in GTA VI appears to use a substantially more advanced physics model than previous Rockstar titles. Analysis of trailer footage and patent filings reveals several systems working together.
3436  
3537 SystemDescriptionTidal dynamicsWater levels change over time. Docks, beaches, and marshlands show realistic tidal interactions, with high water marks left behind as tides recede.Depth-based colorWater appearance shifts based on depth and sediment. Shallow water over sand and limestone appears lighter; deep ocean water appears dark blue, using realistic light absorption and scattering.Vehicle displacementBoats and jet skis create ripple effects with realistic displacement. Waves have mass and drag; a speedboat against the current slams down physically.Wet sand saturationA saturation map shows varying degrees of sand dampness. Darker, reflective wet sand remains for a period after water recedes, simulating natural drying.Flood accumulationDuring storms, water pools in low spots and collects against barriers. Puddles form dynamically based on terrain contours rather than using flat pre-placed decals.Character interactionWhen a character exits water, it deforms, splashes, and creates puddles dynamically around them.
3638 Underwater Environments
3739  
3840 Scuba diving is confirmed. On the official GTA VI website, imagery for Leonida Keys depicts a diver swimming in an ocean filled with underwater wildlife including eels, turtles, coral, and fish. Rockstar describes the Keys as having "some of the most beautiful and dangerous waters in all of America."
3941  
4042 The underwater rendering appears substantially improved over GTA V's ocean. Visible details include coral reef ecosystems, sea turtles swimming alongside divers, and total internal reflection on the underside of water surfaces, a physically accurate optical effect where light bends at the boundary between water and air. Two divers in full scuba gear are shown near a coral reef in one of the official screenshots.
4143  
4244 Tropical Climate and Biomes
4345  
4446 Consistent with the Florida setting, Leonida's climate is predominantly tropical and subtropical. Bright sunshine dominates daytime scenes, with lush vegetation, palm trees, and warm-colored lighting. The state's varied geography means environmental conditions differ significantly by region.

4952 Over 25 animal species are confirmed from official trailer footage and screenshots. The variety reflects Leonida's diverse biomes, ranging from urban streets to deep swamp to open ocean.

5255 Individual grass blades are modeled according to game artist analysis of the trailer footage, representing a level of vegetation detail not seen in previous GTA titles.

5457 Extreme Weather
5558  
5659 Earlier reporting suggested that hurricanes or tropical storms might be featured in the game. However, more recent reporting indicated these extreme weather events may have been scaled back or cut during development. Rockstar has not made any official statement about extreme weather systems. As of early 2026, no hurricanes, tornadoes, or other severe weather events have appeared in official materials.
5760  
5861 Neon Nightlife
5962  
6063 Vice City is explicitly described by Rockstar as having "neon-soaked streets." Nighttime scenes in both trailers and the 70-plus official screenshots released in May 2025 feature neon signs, purple dance floor lighting, police sirens reflecting off surfaces, streetlamps, and helicopter spotlights. The variety of light sources at night, including neon signs, vehicle headlights and taillights, traffic lights, office fluorescents, emergency sirens, explosions, and streetlamps, creates a dense, layered nighttime atmosphere.
