OpenUV

OpenUV provides a global real-time UV index API. The service combines meteorological inputs (ozone, cloud cover, area reflection) with NASA satellite sources to return current UV index, daily maximum UV, ozone level, safe sun-exposure times per Fitzpatrick skin type, and a recommended sun protection window for any geographic coordinate.

Features

Real-Time UV Index

Current UV index for any latitude/longitude with ozone-adjusted and cloud-adjusted calculations.

UV Forecast

Time-series UV index forecast (hourly) including sun position at each forecast step.

Sun Protection Window

Recommended start/end times each day when UV index crosses configurable protection thresholds (default 3.5).

Safe Exposure Times

Minutes of safe unprotected sun exposure for all six Fitzpatrick skin types (st1-st6).

Ozone Data

Live total column ozone in Dobson units used in the UV calculation.

Altitude Adjustment

Optional altitude parameter for elevation-corrected UV readings.

Sun Position

Solar azimuth and altitude returned with each UV reading and at each forecast step.

API Usage Statistics

Per-key request and cost statistics for today, yesterday, this month and last month.

Health Check

Lightweight /status endpoint for uptime checks before making metered requests.

Use Cases

Weather Apps

Add live UV index, daily UV max and skin-type-specific exposure recommendations to consumer weather apps.

Smart Home Automation

Trigger blinds, awnings or wearable reminders when UV crosses a threshold (e.g. via Home Assistant or openHAB).

Outdoor Activity Planning

Surface safe-exposure minutes and protection windows in hiking, running, cycling and sailing apps.

Sunscreen Reminders

Notify users when to apply or reapply sunscreen based on the protection window endpoint.

Solar and Agriculture

Combine UV, ozone and sun position with solar generation or crop UV-stress models.

Public Health Research

Aggregate UV exposure data across populations and geographies for skin-cancer research.

Travel Advisories

Show destination-specific UV risk to travelers before and during trips.

Integrations

Home Assistant

Official OpenUV integration providing UV index, max UV, ozone, protection window and safe-exposure sensors.

openHAB

openHAB binding for OpenUV exposing UV channels in smart-home rule engines.

Homey

Homey app integration for triggering UV-based flows.

ioBroker
