El Niño Observatory
Weather
$0.99 · Designed for iPad. Not verified for macOS.
El Niño is entering an active phase, and heatwaves, torrential rain, droughts and unusual typhoons are playing out across the globe. El Niño Observatory connects macro climate watching with the daily actions of you and your family — a personal climate-adaptation toolbox for the El Niño era.
TODAY · LOCAL CLIMATE PANEL
Local weather plus soil temperature and moisture (data from Open-Meteo) — your city's climate state at a glance.
PROTECT · HEAT GUARD
Feels-like temperature and heat-stroke risk levels, the coolest windows for going out and exercise, hydration reminders (local notifications), and a dedicated hot-day protection mode.
PREP · FAMILY EMERGENCY
A fully offline disaster-prep module: emergency kit checklists customized per hazard (checkable, with expiry reminders), a family evacuation plan card (meeting points, emergency contacts, pet arrangements), and guides for handling water, power and gas outages. Works through typhoons, blackouts and network outages.
FARM · PLANTING ASSISTANT
Sowing and harvest window advice based on accumulated and soil temperature; drought, waterlogging and frost alerts. Great for home gardening and balcony vegetables.
ENERGY · POWER SAVER
Hot-weather electricity reminders, off-peak usage advice, and plain-language explainers on air-conditioner settings vs. power draw.
EXPLORE · ENSO OBSERVATORY
Live Niño 3.4 SST anomaly and ONI index status; the full ONI record since 1950 with major El Niño / La Niña events annotated; a global impact map (drought and flood regions, province-level impacts for China); ENSO impact scores for agricultural and energy futures; and a climate encyclopedia. Data updated daily.
