Været i Yogyakarta (Jogja) i april

Regulars are specific the official rainy season here runs September through April with its peak around mid-January to mid-February, putting this month just outside that peak window on paper, though real rain remains common regardless. Our row backs that hot, genuinely wet read, 29.6C reading as a scorching 35C, over 22.6C nights feeling 27C, with a substantial 158.6mm of rain across 19.4 days and humidity at 86 percent. Regulars are consistent any rain that does fall tends to be short rather than heavy, typically arriving in the afternoon or evening, morning visits to temples and outdoor sites the standard advice to work around it. Genuinely hot and humid conditions remain the bigger day-to-day factor than the rain itself. The sea sits at a bath-warm 28.9C. The record: 10.1 hours of sun, a 10.9 kph wind and AQI 61.

February is the wet season at its peak - regulars date that peak from the middle of January to the middle of February - and our column agrees emphatically: 350.6mm across 26.4 days at 89.3 percent humidity. What they say next is the useful part, and they say it flatly: the wet season will have no real impact on your plans, take an umbrella. The temples do not close for rain, and the rain is not all day. The heat is steady rather than fierce, 28.8C reading as 35C in that humidity, with nights at 22.9C. Sunshine still runs 8.3 hours a day. The record: an 11 kph wind and AQI 68.

Regulars date the dry season from May to October and recommend anything inside it, which puts June comfortably in the window - but our row says the window has a slope. June carries 128.7mm across 18.1 days; July and August carry about 45mm across ten. So June is the dry season arriving rather than the dry season, and the difference is visible: rain on three days in five here, on one in three a month later. It still matters for the temples, because the wet months give you cloud and mist instead of a view, and the sunrise trip wants a clear morning and Merapi behind it. Heat is the constant, 29.4C reading as 34C at 84 percent humidity. The record: 22C nights, 10.3 hours of sun and AQI 57.

July to September is the dry season regulars name for Jogja, and the reason they give is specific: this is when the Borobudur sunrise actually works, the sun coming up between Merapi and Merbabu over mist sitting in the villages, where a wet-season visitor mostly gets cloud. The run is a 4am departure from the city for about 5:30 at the temple. Our row is less confident in September than they are - 113mm across 14.6 precipitation days is the tail of the dry season already turning, so the first half of the month is the safer half. Heat is the other factor: 29.9C over 21.8C at 81 percent humidity reads as 34C, which is why the dawn start is not only about the light. The record: 10.7 hours of sun and AQI 50.
