Control Weather 5e: Stages, Timing, and Spell Limits

I love Control Weather because it feels less like casting a combat spell and more like changing the world around the adventure. It is enormously powerful over time, but its long casting time and gradual changes make planning far more important than initiative order.

Control Weather 5e — Quick Spell Reference

How Control Weather Works in 5e

You take control of the weather within 5 miles of you for up to 8 hours. You must be outdoors to cast the spell, and it ends early if you no longer have a clear path to the sky. It also requires concentration.

When you cast the spell, the Dungeon Master determines the current precipitation, temperature, and wind based on the climate and season. You can alter each of those three conditions, but only by moving it one stage up or down on the spell’s tables.

The new conditions do not arrive immediately. Each requested change takes 1d4 × 10 minutes to take effect. Once a change is complete, you may change the conditions again, one stage at a time.

The Weather Stages

The 2014 spell organizes weather into three separate tracks. Each movement between adjacent rows is one stage.

Track	Stages, from one extreme to the other
Precipitation	Clear → light clouds → overcast or ground fog → rain, hail, or snow → torrential rain, driving hail, or blizzard
Temperature	Unbearable heat → hot → warm → cool → cold → arctic cold
Wind	Calm → moderate wind → strong wind → gale → storm

You can work toward several changes over the spell’s duration, but you cannot jump directly from clear skies to a blizzard. Every single-stage shift requires its own 1d4 × 10 minute transition.

What Does the Weather Actually Do?

Control Weather changes the weather; it does not independently assign damage, conditions, or saving throws. The Dungeon Master applies the game’s environmental and visibility rules where appropriate.

For example, fog or heavy precipitation might obscure vision, strong wind might affect ranged attacks or flying creatures, and extreme temperatures might call for environmental checks. The spell does not let you call targeted lightning bolts or automatically damage creatures simply because you created a storm.

Timing, Concentration, and Ending the Spell

The 10-minute casting time makes Control Weather difficult to use as a surprise combat tactic. Taking damage while casting a spell with a casting time longer than one action does not trigger a concentration check for this spell yet, but you must spend your action each turn casting and maintain concentration during the casting process under the general spellcasting rules.

After the spell takes effect, losing concentration ends your control. The weather then gradually returns to normal, as the spell describes, rather than snapping back instantly.

Because this is an 8th-level spell with no higher-level entry, it cannot be upcast for a larger radius or longer duration.

What Changed in the 2024 Rules?

The overall spell remains recognizable in the 2024 rules: it still has a 10-minute casting time, a 5-mile radius, concentration up to 8 hours, three weather tracks, and gradual one-stage changes.

The main wording changes are:

• The material component is simplified to burning incense.
• The spell ends if you go indoors, replacing the 2014 wording about no longer having a clear path to the sky.
• The Dungeon Master determines the current conditions without the explicit 2014 instruction to base them on climate and season.
• Some temperature-stage labels are updated, including Heat Wave and Freezing.

Control Weather FAQ

Can you cast Control Weather indoors?

No. Both versions require you to be outdoors when you cast it. Under the 2014 rules, it also ends if you no longer have a clear path to the sky.

Does the weather change immediately?

No. Each one-stage change takes 1d4 × 10 minutes to take effect.

Can Control Weather create a blizzard from clear skies?

Eventually, if the Dungeon Master agrees that snow is the appropriate precipitation and you maintain the spell long enough. You must move through every intervening precipitation stage separately.

Can Control Weather call lightning or deal automatic damage?

No. It changes weather conditions but does not grant the separate effects of spells such as Call Lightning or assign automatic damage.
