BMKG Sikka Forecasts Settled Weather for Sikka, Ende and Nagekeo on 20 September

Ende — — The Meteorology, Climatology and Geophysics Agency (BMKG) station in Sikka forecasts generally settled weather across Sikka, Ende and Nagekeo on Sunday, 20 September 2026, with air temperatures between 21°C and 32°C, according to a bulletin reported by RRI Ende.

The forecast calls for clear to partly cloudy skies from morning through afternoon, shifting to partly cloudy to cloudy conditions from night into early morning, RRI reported, citing BMKG forecaster Burhan.

For visitors, this outlook suggests that daytime sightseeing and road travel may start under relatively stable skies.

However, the forecast is regional and does not amount to a guarantee that every route will remain dry, that visibility will always be clear or that sea journeys will be comfortable.

BMKG Sikka forecaster Burhan said winds across the three districts are expected to come mainly from the southeast, with average speeds of about 10–20 kilometres per hour, according to the same report.

The bulletin provides a district-wide view and does not give route-by-route assessments for roads, ferry crossings, small boats or individual tourist sites.

Daytime conditions and temperatures

Clear to partly cloudy conditions generally indicate that forecasters do not expect widespread rain during the main daytime period.

RRI’s summary of the BMKG outlook for 20 September does not mention a specific probability of afternoon showers or thunderstorms for individual locations.

Travellers are therefore advised to treat the forecast as a planning guide rather than a safety clearance.

Before departure, visitors should check BMKG’s latest updates and confirm conditions with transport operators, particularly when itineraries involve exposed coastlines, small vessels or remote roads.

The temperature range highlighted by BMKG — lows near 21°C and highs around 32°C — can produce noticeably different conditions between early morning, midday and evening, depending on elevation and proximity to the sea.

Visitors should be prepared for heat during the day and carry suitable sun protection and drinking water, while remaining ready for cooler conditions at night and at higher altitudes.

Key elements from the BMKG Sikka forecast as relayed by RRI include:

• Air temperature: around 21–32°C in Sikka, Ende and Nagekeo
• Dominant wind: Southeast, averaging about 10–20 km/h
• Daytime sky: Clear to partly cloudy from morning to afternoon
• Night and early morning: Partly cloudy to cloudy

These figures describe the general outlook for the three districts and should not be read as a substitute for current local warnings or an operator’s decision to delay a trip.

Sea conditions a key concern

Although land weather is expected to be broadly favourable, BMKG Sikka highlighted a difference between northern and southern waters of Flores.

According to the RRI report, northern Flores waters are forecast to have low waves of about 0.5–1 metre, while southern waters are expected to see moderate waves of about 1.25–2 metres.

That distinction is important for coastal residents, fishers and visitors planning boat travel.

A low-wave forecast for the north does not automatically apply to southern routes, and a regional bulletin cannot confirm conditions at a particular harbour, landing point or crossing.

People travelling by sea should therefore check the latest marine information before departure and follow advice from skippers, ferry companies and local authorities.

The wind forecast also needs to be considered alongside wave height.

Average winds of 10–20 km/h can still affect smaller boats, coastal activities and exposed areas, especially where they coincide with moderate waves on southern routes.

Drought-related risks in East Nusa Tenggara

Beyond the immediate forecast for Sunday, BMKG has repeatedly warned that dry-season conditions in East Nusa Tenggara can lead to clean-water shortages and raise the risk of forest and land fires.

In earlier advisories on largely clear-weather days, BMKG Sikka has linked prolonged dry spells and warm temperatures with faster spread of fire hotspots and called for vigilance from communities, according to regional reports.

Residents and visitors are generally urged to use water carefully, avoid activities that could start fires and remain alert to fire-prone areas, particularly near grassland, scrub and plantations.

On days with stronger winds, falling branches or trees can also become a concern in dry or vulnerable areas.

BMKG issues its forecasts and warnings through official channels, and regional media such as RRI regularly relay these updates to the public.

Visitors planning trips in Flores are advised to consult BMKG’s latest weather and marine bulletins close to departure and to monitor local advisories on drought, fires and transport conditions.
