MUSCAT: Oman recorded its highest average maximum temperature in three years during 2025, according to data released by the National Centre for Statistics and Information (NCSI), highlighting a warming trend across the Sultanate of Oman amid notable shifts in humidity and rainfall patterns.
The average maximum temperature climbed to 34.1°C in 2025, up from 32.9°C in 2024 and 32.8°C in 2023, marking the highest level recorded during the three-year period under review.
At the same time, humidity levels declined significantly. The average maximum humidity fell to 66.4 per cent in 2025 from 72 per cent in 2024 and 74 per cent in 2023.
Also the average minimum humidity witnessed an even sharper drop, reaching 21 per cent compared with 41 per cent last year and 45 per cent in 2023.
Rainfall patterns also showed considerable fluctuations. After surging to 80.4mm in 2024, rainfall moderated to 38.6mm in 2025, although it remained well above the 15.4mm recorded in 2023.
The data further showed changes in average minimum temperatures, which stood at 21.1°C in 2025, compared with 25.4°C in both 2023 and 2024.
NCSI noted that figures for 2023 and 2024 were based on observations from Muscat International Airport weather station, while the 2025 values represent the results of a statistical modelling exercise covering the Sultanate of Oman as a whole.
The latest indicators point to increasingly warmer conditions across the country, with higher daytime temperatures accompanied by lower humidity levels, underscoring the evolving nature of Oman’s climate and weather patterns.
