Terrain-Aware Requests: How Elevation Affects the Numbers You Get Back and What to Do About It
Elevation silently skews temperature, pressure, and precip-type readings. Here’s how to detect and correct for it when building on WeatherAPI data.

Why obs_time Lies: Understanding Observation Age in Real-Time Weather Responses
The current weather your API returns may be 90 minutes old. Here’s how obs_time works, when to trust it, and how to handle stale observations in production.

isDay, Sunrise, and Sunset: Why You Can’t Derive One from the Other
WeatherAPI returns isDay, sunrise, and sunset as separate fields. Here’s why they diverge, when each breaks down, and which to use for what.

Decoding air_quality in WeatherAPI Responses: What the Index Values Mean and When They Break Down
A deep dive into WeatherAPI’s air quality fields — what pm2_5, us-epa-index, and gb-defra-index actually measure, where they come from, and when not to trust them.

gust_kph vs. wind_kph: Why Peak Wind and Sustained Wind Are Different Problems
gust_kph and wind_kph measure fundamentally different things. Here’s what that means for thresholds, alerts, and real-world decisions in your app.

Precipitation Accumulation Windows: Why hourly_precip_mm Doesn’t Add Up to daily_precip_mm (And How to Work Around It)
hourly_precip_mm rarely sums to daily_precip_mm in weather API responses. Here’s why the windows don’t align and how to handle it in your code.
