Seasonal Travel Tips for December
- Start days early. Sunrise is around 7:15 a.m.; morning daylight is clearest. Visit major sites between 8–11 a.m. for optimal weather conditions and fewer visitors.
- Adjust afternoon rhythm. The 2 p.m. heat and sun glare can be intense. Rest indoors 1–3 p.m., then return to sightseeing as light softens (4–6 p.m.). This maximizes daylight hours.
- Book museums and attractions in advance. December crowds mean popular destinations fill mid-morning. Reserve timed entry to avoid disappointment.
- Altitude adjustment. Mexico City’s elevation can cause mild headaches. Drink extra water, avoid rushing on day one, and eat light meals while acclimating.
- Embrace the cold mornings. A 7 a.m. market or archaeological site visit is rewarding; bring coffee and a jacket. Sunrise visits to iconic sites offer unmatched views.
- Sunscreen is non-negotiable. Even on cool-feeling days, the altitude and clear skies intensify UV exposure significantly.
- Check weather stations for hourly updates. While weather forecast reliability is high, hourly temperature fluctuations can be notable between morning and afternoon.
