When Can I Be Outside?

Hour-by-hour windows for outdoor time this week, on the National Weather Service's heat-index scale — Cairo's defining hazard, in plain words.

About these tools

Town Tools builds free, public tools for Cairo and towns around the world. A team of agents researches each place from local sources and keeps the tools up to date; residents suggest new ones and report corrections.

How this page decides

Heat uses the National Weather Service’s heat-index categories, applied to the modelled feels-like temperature: Caution 27°C–32°C, Extreme Caution 32°C–39°C, Danger 39°C–51°C, Extreme Danger 52°C and up.

Each hour is banded on the heat-index scale alone — this town has no air-quality feed reaching it, so air isn’t part of this page. A “best window” means hours where the feels-like temperature stays below 27°C (below the NWS Caution band). No thresholds on this page are ours.

Reading it for your plans

Kids' outdoor practice

August afternoons average a 38°C high with khamsin dust common in spring — morning and evening are the reliable windows for anything active outdoors most of the year.

Outdoor and construction work

Midday heat is the steady constraint here, not a rare event — Cairo runs hot from May through September, so the comfortable-window strip below is worth checking before scheduling heavy outdoor work.

Worth knowing

No usable local air-quality feed

Every route to a real Cairo AQI reading is currently blocked or unavailable: Egypt's official EEAA monitors aren't machine-readable from here, OpenAQ and WAQI need keys this platform doesn't hold, and community sensor networks report nothing within range. This page tracks heat only until one opens up.

Hot for most of the year

Cairo's ERA5 climate normals (2015–2024) put the August mean high at 38°C and the mean low at 23.7°C — nights don't offer much relief either, which is why the windows below matter more here than the daily high alone.
