Dubai vs Tokyo
Re-score for me — drag the dial — every chart recolours live for your heat & sea limits 27°C · sea 29°C
Default 27 °C is the upper edge of the Holiday Climate Index "ideal comfort" band (Scott, Rutty, Amelung & Tang, 2016). Above this, most warm-tourism travellers report measurable discomfort.
Default 29 °C is the Beach Climate Index "bathtub" line (Morgan et al.) — where the sea stops being refreshing and starts feeling like a warm bath.
Dubai peaks in January, February, December (annual avg 5.8/10). Tokyo peaks in November, October, May (annual avg 5.9/10).
Dubai upper vs Tokyo lower
Dubai — sea
Dubai. Visit November through March, when daytime temperatures sit in the low-to-mid 20s and the desert is genuinely pleasant. February and March are the sweet spot — warm enough for the beach, cool enough for desert excursions. June through September is unsuitable for outdoor tourism: 40°C+ daily, heavy humidity off the Gulf, and most outdoor activities effectively shut down.
Tokyo. Visit in late March to early May for cherry blossoms and mild weather, or October–November for crisp clear days and autumn foliage. Avoid late June through August: hot, humid, and rainy.
