Reading the seasons
Station
JMA's Naha observatory (block 47936) stands 28.1 m above sea level in Naha's Higawa district. Every figure in this file is JMA's published 1991–2020 normal, and rain days count the days with 1 mm or more.
Winter
Okinawa's north-east monsoon starts around early October, and locals call its first cool push *miinishi* (literally the new north wind). From December to March the most frequent wind at Naha blows from the north-north-east or due north at an average of 5.2–5.3 m/s. The day's strongest wind reaches 10 m/s or more on 7.6 to 8.8 days a month in that stretch. February averages a high of 20.2 °C and a low of 15.1 °C, with 93.1 hours of sunshine across the month.
Spring
In early spring a low from the East China Sea sometimes deepens fast as it crosses Okinawa. Once its cold front passes, a southerly wind swings round to a strong north or north-east wind and the temperature drops. Okinawans have long called this *ningwachi kajimaai* (the wind turn of the second lunar month).
Summer
When the rainy season ends in late June the Pacific high pushes west and a strong south to south-west wind called *kaachiibee* blows steadily for several days. Naha's most frequent wind in July and August comes from the south-east.
Typhoon
JMA counts a typhoon as approaching the Okinawa region when its centre comes within 300 km of a station there, and the 1991–2020 normal is 7.7 approaches a year. August averages 2.2 approaches and September 1.9. Across those 30 years JMA recorded no approach at all from January to March.
Rainy
JMA's 1991–2020 average puts the start of Okinawa's rainy season around 10 May and its end around 21 June. JMA's preliminary dates for 2026 were around 4 May and around 29 June. Okinawans call the season *suuman boosuu* after two of the old solar terms that fall inside it. June is Naha's wettest month at 284.4 mm.
Sea
Sea temperatures are our monthly averages of JMA's daily 1991–2020 sea surface normals at its fixed point off the south coast of Okinawa Island (沖縄本島南). The monthly figure runs from 22.2 °C in February up to 29.2 °C in August.
Wind
The windDir field holds JMA's most frequent wind direction (最多風向) for each month as the 16-point compass point the wind blows from.
