🌧 Rain : ███░░░░░░░ 31%

🌡 Temperature : ██████░░░░ 79°F

☀️ Sunshine : ████████░░ 10.6h/d

Our take: January is peak season here for good reason—you'll enjoy warm, comfortable days around 25-26°C with over 10 hours of daily sunshine. Rain's always possible (31% chance), but showers tend to be brief tropical bursts that cool things down nicely rather than ruin plans. It's genuinely the sweet spot if you want reliable beach weather without the oppressive heat of summer.
