Romania Weather by Month

Sources and Methods

The place comparison covers 2596 named towns, resorts, castle areas, natural areas and Delta stops across Romania, including every overnight base in our trip planner and a high-mountain point near Vârful Omu. All base climate figures use one ERA5 record and the same 1991–2020 period. Daily maximum and minimum temperatures are calculated from hourly 2 m temperatures for UTC calendar days; precipitation is the monthly mean total; wet days count daily totals of at least 1 mm. Values are rounded to one decimal place.

ERA5 is a gridded reconstruction of the climate. Nearby places can share a 0.25° grid cell, and its terrain height can differ from the town or summit. The separate station table contains observed WMO normals; those figures are never substituted into the base comparison. Sunshine appears only in the station table. Daylight is the calculated mean sunrise-to-sunset duration across all days in each month and includes cloudy hours.

We checked 31152 calculated named-place monthly rows and 312 official station monthly rows for complete values; all 31464 were retained. Repeated city and month values stay in the tables; the findings summarise distinct comparisons. Climate data are next reviewed in May 2027; seasonal access follows the linked operators' notices.
