Humidity levels range from 45-80%, with north winds at force 4 to 5, occasionally stronger offshore. The probability of significant rain remains low, but the replenishment of the northeast monsoon signals progressively cooler weather through the holidays, affecting coastal and inland areas differently.

Global Weather Impacts on Dec 25

In Nepal, dense fog persists across Tarai regions on December 24 into 25, disrupting daily activities until midday in some provinces. Hilly and mountainous areas remain mainly clear, creating stark contrasts in visibility and travel safety.

La Niña influences the US Winter 2025-26 outlook, forecasting colder temperatures in the northwest and northcentral regions through February, with warmer, drier conditions in the south. Wetter patterns hit the Pacific Northwest and Ohio Valley, relevant for holiday storms on December 25.

Holiday Travel and Preparation Tips

With global cooling trends, pack layers for sudden drops, especially in Asia where morning chills and evening winds dominate. Monitor fog in South Asia and potential snow in Europe for flight delays.

US travelers in northern areas should anticipate La Niña-driven cold snaps, while southern regions enjoy milder weather. Check sea temperatures around 22°C in Hong Kong for marine activities.
