You step out of the drop pod into a sky that feels like it’s watching you. Your mission log blinks: Weather Monitor System — five stages, scattered parts, and a stubborn reward waiting at the end. I’ve raced this one enough times to know which runs are theater and which actually move the needle.
Read this like a field manual: short moves, focused priorities, and a plan you can repeat on every run. I’ll point at the parts that slow most players down, where to stack materials, and the fastest way to turn those runs into Raider Tokens and a cosmetic charm.
How to Complete Weather Monitoring System in Arc Raiders
On a typical sortie you’ll notice some items drop more often than others — plastic and metal parts are everywhere, rarer modules less so.
I’ll be blunt: this project is a grind, but it’s a predictable one. The Weather Monitor System is split into five stages, each asking for specific components and returning a mix of consumables, weapon parts, and the big payout: Raider Tokens and the Anemometer backpack charm. Treat each stage like a short checklist and you’ll avoid the scatter that kills momentum.
How do I complete the Weather Monitor System project quickly?
Start small and stack. Knock out stages that use common drops first (plastic, metal, duct tape) so you claim early rewards while you hunt rarer items. Run curated zones where those materials spawn most — concentrate on routes that let you clear enemies, open a few chests, and extract. If you play with a squad, assign scav tasks: one person clears mobs, another hunts chests, the third loots portable supplies.
Tip: prioritize runs that reward Processor/Advanced Electrical Components if you need Stage 2 items; those components often come from higher-tier caches and boss drops. Treat each run as a shopping trip, not an art heist — efficient, repetitive, and a little boring by design.

The table below lists every stage, what each stage needs, and the rewards you’ll get for finishing.

What materials are required for each stage of Weather Monitor System?
Read the table and mark what you’re missing before you step into a run. Common components like plastic parts and metal parts will arrive naturally. Special items — Snitch Scanner, Comet Igniter, Fine Wristwatch — are rarer and often tied to higher-tier enemies or boss caches.
Farming rhythm matters: stack runs that drop the same category of item. If you need more electrical parts, queue missions that end with an advanced cache or target named enemies. If you’re short on medical supplies or cloth, low-tier zones and supply stashes will refill those quickly.
When Does Weather Monitor System Project End in Arc Raiders?
During my last check the project had no expiry listed inside the game — it sits in your project tab until the developers decide otherwise.
That means you can pace yourself, but pacing comes with a trade-off: rare items tend to sit behind the same boss fights that are fun to clear — so procrastination can cost you time. If you want the Anemometer charm and 250 Raider Tokens fast, concentrate on the rare module stages first and let everyday runs cover the basics.
Does the Weather Monitor System project expire?
There’s no in-game timer shown now. That could change if a new seasonal push or Expedition update arrives, so keep an eye on official channels: Steam pages, platform patch notes on Xbox/PlayStation, and the game’s social feeds or Discord and Reddit communities for announcements.
Two final quick habits from my runs: tag the rare items you need before each mission and run with a consistent loadout that clears enemies fast — pick speed over spectacle. Treat the project like a short campaign, not a one-off heist; rewards compound when you repeat the same efficient loop, and the charm feels earned, not given.
Is it worth the grind for the tokens and cosmetic — or are you saving your time for the next update?
