Dynamic Seasons Mod — Spring Summer Fall Winter for GTA 5 (2026)

Dynamic Seasons — Four Seasons Mod for GTA 5

The Dynamic Seasons mod introduces a complete four-season cycle to GTA 5, transforming Los Santos and Blaine County with distinct visual changes for spring, summer, fall, and winter. Each season brings unique weather patterns, vegetation changes, lighting adjustments, and atmospheric effects that make the game world feel alive and ever-changing throughout the year.

Spring — Renewal and Growth

Spring brings fresh green foliage to trees and landscapes with blooming flowers and lush vegetation. Frequent rain showers create wet road surfaces and puddles, while rainbow effects occasionally appear after storms. The lighting features soft, warm tones with gentle morning fog. Parks and green spaces burst with color, and longer daylight hours provide extended golden hour photography opportunities. NPC behavior shifts to outdoor activities with more pedestrians in parks and public spaces.

Summer — Heat and Sunshine

Summer transforms Los Santos with intense sunshine, vivid blue skies, and heat shimmer effects on road surfaces. Vegetation is full and green but shows dry brown patches in Blaine County's desert regions. Beach areas are busier with more NPCs enjoying the coast. The harsh midday sun creates strong shadows and bright highlights, while evening brings spectacular sunset skies. Occasional thunderstorms provide dramatic lightning and heavy rain relief from the heat.

Fall — Color and Transition

Autumn paints Los Santos in warm golden and amber tones as trees transition through red, orange, and yellow foliage before shedding leaves. Fallen leaves scatter across sidewalks and roads, moving with wind gusts. The lighting takes on a warm, nostalgic quality with lower sun angles creating long shadows. Fog becomes more frequent in morning hours, especially in valleys and near water. Overcast skies alternate with crisp, clear autumn days featuring deep blue skies.

Winter — Cold and Snow

Winter brings snow to the mountains of Blaine County and Mount Chiliad, with frost effects appearing on vehicles and building surfaces. City areas experience cold rain and occasional sleet, while higher elevations receive full snow coverage. Shorter days mean extended night gameplay with early sunsets and late sunrises. Holiday decorations appear in commercial areas, and NPCs bundle up in winter clothing. Icy road conditions affect vehicle handling on mountain roads.

Installation and Configuration

The Dynamic Seasons mod installs as a script mod with Script Hook V. Season duration is fully configurable — set each season to last a few in-game days or weeks to match your preferred pace. Manual season switching is also available through a hotkey menu. The mod is compatible with visual enhancement mods and works in singleplayer mode.
