January is mid-rainy-season, Bali style: sunny mornings, an hour or two of afternoon rain, warm evenings. The sea hits its warmest (~29°C) — swim at reef-protected Sanur or Nusa Dua, since ocean-facing west beaches collect waves and seasonal debris. Holiday premiums of 30–50% hold until about Jan 10–15, then the island empties and monthly rentals become genuinely negotiable.
