On 14 September 2026 the sun rises in Mexico City at 06:23 and sets at 18:39 — a day of 12h 16m.
The Mexico City page in the paper shows what the sky is doing now — condition, chance of rain, wind and gusts, sunshine hours, UV and rain total, from Open-Meteo — with a storm-watch line when thunderstorms or high winds are forecast; then the hour-by-hour temperature curve for today, a seven-day outlook of highs and lows, and yesterday's almanac (this day last year). The live page needs a script to run; this page is the still version of it.
What a probability means
When the paper says Mexico City has a 68 per cent chance of exceeding 30 °C tomorrow, it means that in an ensemble of weather-model runs, about two in three finished above that line. It is a statement of odds, not a forecast of one number — read it the way you read a chance of rain. The method page explains how the odds are made and how they are checked against what actually happened.
