Worlds & weather

Realistic weather and automatic posting are available on Free.

What belongs to a world?

A world has its own name, fictional date, weather settings, and Discord feeds. Select the world in the dashboard before changing its settings.

Free supports one world per server. Plus supports up to five. See plan limits.

Choose the climate and tone

Climate influences the kind of weather your world produces. The choices are temperate, tropical, desert, mediterranean, continental, coastal, and arctic.

Hemisphere affects the seasonal context. Temperature units control whether messages use Celsius or Fahrenheit.

Choose settings that match the place your characters live. You can refine them in the dashboard after setup. Changes apply to newly generated days; weather that was already generated is not rerolled.

Weather tones

The tone decides how often notable weather happens and whether it can be fantastical. Day-to-day conditions (clear, cloudy, rain, storms, snow, and fog) follow your climate and season in every tone.

Tone	What it does	Plan
Realistic	Believable weather for the climate and season. Notable events are rare.	Free
Dramatic	The same grounded weather, but notable events such as storms and temperature extremes happen more often.	Plus
Supernatural	Natural weather and occasional natural events, plus rare fantasy hazards that no real climate would bring.	Plus

Dramatic and Supernatural are Plus features. Worlds that already used them before they became Plus keep them on Free; new worlds and world copies do not inherit that.

Weather events

On some days a notable event adds a headline to the forecast.

Natural events (all tones): heatwave, cold snap, severe storm, and blizzard.
Fantasy hazards (Supernatural only): an arcane tempest, where arcane lightning moves against the wind; a sunless day, where a dim veil hides the sun until dusk; acid rain, which stings the air and eats at stone; or ashfall, which drifts down and dims the sky.

Events are rare, and the same kind will not repeat straight away, so they stay special. Atlas worlds can also add their own with custom hazards.

Blood Moons

A Blood Moon is a rare, dramatic version of the full moon. It can only happen on a full-moon night, and only some full moons qualify. Blood Moons are a Plus feature and are off by default. Turn them on per world under the world’s weather settings. When one occurs, the moon bulletin announces it.

Like all weather, which nights are Blood Moons is fixed for each world, so viewing a day again always shows the same result.

Regions: different weather in different places

A region is a location in your world with its own weather. Each region can use its own climate (or follow the world’s), a temperature offset, a wetness multiplier, and a latitude band. Raise the wetness multiplier for a region that is rainy and stormy more often than the rest of the world, or lower it for somewhere dry. Free supports 3 regions per world and Plus supports 25. See plan limits.

A feed can follow one region, and members can use the region option on /weather and /forecast. See commands.

Manual overrides: story-driven weather

When the story calls for specific weather, add a manual override in the dashboard. An override replaces the condition, temperature, or summary for a roleplay day you choose. It can cover one period (morning, afternoon, evening, or night) or the whole day, and it can apply to the whole world or a single region.

Overrides replace what is displayed while the generated forecast stays underneath, so deleting an override brings the original weather back. An override covers one roleplay day. To hold weather across several days, use a condition lock instead. Weather editors can add overrides, and the dashboard also supports staff approval requests for changes.

Holding weather across days

Under Weather continuity in the dashboard you can keep the weather the same, or give it a name, across a run of days.

Condition lock: holds one condition (clear, cloudy, wet, storm, snow, or fog) from a first roleplay day to a last one. Add a short weather text, such as “The sky is black and bolts arc overhead.”, and Weatherly shows it instead of the standard line. A lock on the whole world with an end date is available on Free.
Region-specific locks (Plus): choose Applies to to hold the condition in one region only, so the other regions keep their own weather.
Ongoing locks (Plus): tick Ongoing, with no end date for a place that is always the same, such as a permanent storm. It holds until you delete the lock from the list below the form.
Weather sequence (Plus): plan a run of weather ahead of time, such as a boss phase. Give the sequence a name, a first roleplay day, and up to 12 steps. Each step has a condition, a number of days, and optional weather text, and starts the day after the previous step ends. A sequence can cover up to 365 days in total, and it can apply to the whole world or to one region. It saves as one group, so deleting it from the list removes every step at once.
Named weather event: gives a stretch of days a name, such as “The Long Dark”, which appears in each day’s forecast. It does not change the conditions. An event can name specific regions, which you can tick on the form; it then appears only in those regions’ forecasts, and an event with no regions ticked appears everywhere.
Weather templates (Plus): save a condition, name, and length once, then apply it from the current day in one step.

Locks apply to days Weatherly has not generated yet. Days that were already generated keep their saved weather, so create a lock before the story reaches those days.

When a region and the whole world are both locked on the same day, the region’s own lock wins, however recently each was created.

For example, a stormy zone that never clears is a region with an ongoing storm lock. A one-off scene, such as a boss fight that darkens the sky for three days, is a condition lock on those days, or an override if you need to set a particular temperature.

Seasonal profiles (Plus)

Plus can replace a climate preset with a custom seasonal profile: the average temperature, wetness, and daylight hours for each season. It applies to newly generated days, and stored history never changes.

Region seasons (Atlas)

Under Region seasons in the dashboard, pick a region and give it its own seasonal profile, such as a scorched wasteland beside a temperate coast. That region uses its own seasons while every other region keeps following the world’s. Choose Follow the world again to remove a region’s own seasons. Like all weather settings, region seasons only affect days Weatherly has not generated yet.

If you would rather not start from scratch, Start from a preset fills the form with a Desert, Tundra, Rainforest, Highlands, Volcanic, or Off-world (no seasons) starting point. A preset only fills the form; nothing changes until you save, and you can adjust every value first.

Custom hazards (Atlas)

Under Custom hazards you can invent rare weather of your own, such as a gravity storm. Give each hazard a name, the line the forecast should show, and a chance per day from 0.1% to 5%. A hazard can turn up under any weather tone and appears in the forecast exactly as you wrote it. Each world can have up to five. Hazards you add never change weather that was already generated, and removing one leaves earlier forecasts as they were.

You can also decide where and when a hazard can happen:

Days before it can return sets how long a hazard stays away after it appears, from 1 to 60 days. The default is 10.
Seasons limits it to the seasons you tick. Leave them all unticked for every season.
Regions makes it local weather that only happens in the regions you tick, and never in the world forecast. Leave them all unticked for the whole world. A permanent storm over one place is better done with a condition lock; a region hazard is for storms that come and go there.

The form shows the chance as a plain frequency, such as “about once every 100 days”, so you can judge it at a glance.

Preview before you save (Atlas)

The Preview buttons under Region seasons and Custom hazards show the next 30 days with your unsaved changes, so you can see what a setting does before you commit to it. The preview starts at the first day Weatherly has not generated yet, includes any condition locks you have set, and stores nothing. Days that are already generated keep their weather.

World packs (Atlas)

Under World pack you can download a file describing a server’s weather setup: its regions (with their own seasons), the world’s seasons, and its custom hazards. Anyone can download one, but importing is an Atlas feature. Importing adds to a server and never overwrites: a region or hazard whose name already exists is skipped, and new regions get their own weather so they do not copy another server’s days. The world’s own seasons are replaced only if you tick the box for it. A hazard tied to regions the server does not have is skipped rather than turned into a world-wide one. Weather locks, sequences, events, and anything tied to specific RP days are not part of a pack.

Saved weather stays consistent

Weatherly keeps a canonical forecast for each generated roleplay day. Viewing that day again does not reroll the weather.

Post now publishes the current day; it does not mean “generate a different forecast.” Advance the roleplay date when you intend to move the story forward.

Reading a forecast

Posts can include temperature, conditions, precipitation, wind, and a daily outlook. A day’s weather has morning, afternoon, evening, and night periods.

The following is an illustrative scene, not a live forecast:

Morning fog hangs over the coast. By afternoon, rain reaches the harbor and the wind strengthens.

Use the forecast as shared context for roleplay. Weatherly describes fictional conditions; it is not a real-world weather warning service.
