Deviant Weather

Deviant Weather — your weather, in context.

Most weather apps tell you what the weather is. Deviant Weather tells you how unusual it is. Every reading — temperature, pressure, wind, humidity, and more — is compared against years of local climate history, so you instantly see what's normal for your location and what isn't.

It's the difference between "68°F and cloudy" and "68°F — notably cooler and much cloudier than usual for this time of year."

KNOW WHAT'S NORMAL. SPOT WHAT'S NOT.
• A dozen conditions analyzed for anomalies — temperature, feels‑like, dew point, humidity, pressure, wind speed and gusts, cloud cover, UV, and precipitation
• Baselines built from up to a decade of real local history for your exact location — not a global rule of thumb
• "For this time of year" comparisons that account for the season and time of day
• Thresholds calibrated to each place's own climate, so a small wobble never gets flagged like a true outlier
• Plain‑language summaries with the numbers behind them: "Current temperature is 68°F vs. the historical average of 74°F — 6° cooler than typical"
• Month‑to‑date trends and extreme‑event detection for the standout days

SEE THE STORY, NOT JUST THE NUMBER
• Interactive 24‑hour charts for temperature, pressure, and wind — current reading, historical average, and the deviation between them, all in one view
• Tap any hour for an exact readout
• A "normal range" band that shows the typical historical range at a glance
• A 10‑day forecast with daily ranges, conditions, and a clear color language (cooler = blue, warmer = red) used everywhere
