Best valueBusy and pricierQuietAverage temperature in Moroni, °C, 2001–2025 (NASA POWER).

Each bar is the average temperature in Moroni for that month, and its colour shows the season for visitors: best value (good weather, fewer crowds and lower prices), busiest and priciest, or quiet (off-peak, sometimes because the weather is poorer).

  • Our pick: May and OctoberThe warmest of the best-value months (26–27°C), with fewer crowds than peak season.
  • Peak season: Jun–SepUsually 25–26°C. The busiest time, so book flights and rooms early and expect higher prices.
  • Quiet season: Nov–AprAround 27–28°C. The cheapest and least crowded time, though often because of rain or heat.
  • Warmest: March (28°C) · coolest: August (25°C)Temperatures barely change through the year, so the season matters more than the weather.
