How it works

What this site is

This site hosts small, single-purpose tools designed to answer one question quickly. Each tool uses publicly available data and simple rules to surface useful guidance.

What the results mean

Results are based on clear thresholds shown on each page. They are meant to reduce uncertainty, not replace judgment. The underlying numbers are always visible so you can decide for yourself.

Data sources

Tools pull data from reputable third-party providers (such as weather forecast services). Data updates regularly and may change as new information becomes available.

Limits

Forecasts and estimates are not guarantees. Local conditions, timing, and personal tolerance all matter.
