How PogoWeather estimates Pokémon GO weather

PogoWeather is a decision-support tool. It does not read Pokémon GO servers and does not have access to an official Niantic weather API. Instead, it estimates likely weather boost locations using Pokémon types, hourly weather data, and a curated list of major cities and hotspots.

The general process is simple: PogoWeather identifies the types of the Pokémon you search for, maps those types to Pokémon GO weather categories, and asks the backend to analyze the configured cities. The result shows an estimated dominant weather, a confidence score, and GPS coordinates.

Why use a backend?

A fully front-end version is easy to test, but all JavaScript code is visible in the browser. That means internal thresholds and provider logic can be copied. This version keeps the sensitive weather logic on the server. The browser only sends the Pokémon and optional custom cities, then receives simplified results.

Why results can differ from the game

Pokémon GO may use different providers, forecasts, cells, and internal rules. Nearby locations can sometimes show different weather. Fog and wind are especially difficult to estimate because they depend on local conditions and provider interpretation.

How to interpret the results

A “likely boosted” result means the city is worth checking. It is not a guarantee. A higher confidence score means several signals agree, especially in precise mode where multiple points around the city are tested.
