Climate overview
Temperature
Monthly mean temperatures are warmest in June, at 35.0 °C, and coolest in January, at 20.9 °C. The mean across the calendar-month means is 28.8 °C; it is an unweighted summary rather than a day-weighted annual average. These figures describe monthly means, not daytime highs, and individual days may differ from the monthly pattern.
Rain
Mean daily rainfall is highest in March, at 0.39 mm/day, and lowest in September, at 0.00 mm/day. The unweighted mean of the monthly daily-rainfall means is 0.21 mm/day. These are daily averages, not monthly totals: the low recorded mean does not establish that every day is dry, or indicate how often rain occurs.
Sunshine
Daily sunshine duration averages 11.88 hours/day in June, the year's highest monthly mean, and 9.68 hours/day in January, the lowest. Across the calendar-month means, the unweighted average is 10.78 hours/day per day. These figures describe average sunshine duration, not day length, and do not guarantee the conditions on a particular day.
Best Travel Time Guide for Muscat, Oman: Ideal Seasons and Weather Insights
Visitors prioritising cooler monthly mean temperatures may consider January, when the mean is 20.9 °C; this is a monthly average, not a prediction of each day's temperature. For lower average rainfall, September is a conditional option, with mean daily rainfall of 0.00 mm/day, but that figure does not guarantee dry days or quantify rain frequency. For outdoor sightseeing planned around sunshine, the monthly daily average is highest in June at 11.88 hours/day, and lowest in January at 9.68 hours/day. Sunshine duration is not day length and cannot promise clear conditions on a visit; the figures can help with broad planning, while flexible plans and preparation for variable daily weather remain sensible.
Rain preparation is especially relevant when visiting in March, the month with the highest mean daily rainfall at 0.39 mm/day. This average is not a monthly total and does not say how rainfall is distributed among days, so it cannot determine whether rain will affect a particular outing.
