December–February
Monsoon exposure matters
Seasonal winds can bring prolonged rain to exposed coasts while other islands are more sheltered. Across East Timor, thunderstorm timing depends on island geography as well as the larger circulation.

THE DAYS AHEAD
East Timor: 7-day weather outlook.
A forecast for the selected place, not for all of East Timor. Days and charts use UTC. Today may cover only the remaining hours.
Thunderstorm guidance is incomplete: a day without a thunder symbol is not an all-clear. Use official warnings for safety decisions.
The forecast loads as you reach this section.
How to use this forecast
Weather symbols describe model guidance for a point. “Thunder signal” means at least one displayed forecast interval contains a thunder symbol or a positive thunder probability. “No thunder symbol” is not an all-clear: lightning probabilities are not supplied for every location or every day, and small storms can be missed.
Rain totals add non-overlapping forecast periods. Temperature ranges include supplied interval extremes and available point samples; wind is the highest sampled sustained wind, not a gust forecast. Later days have coarser time steps and greater uncertainty. Check official warnings and radar again before outdoor plans.
Explore daily humidity, dew point, cloud cover and sea-level pressure. Gusts, apparent temperature, clear-sky UV and period probabilities appear only when supplied. Clear-sky UV assumes no clouds; it is not a forecast of actual UV exposure. A pressure change alone cannot establish whether a storm will develop.

THE YEAR AT A GLANCE
Thunderstorm seasons in East Timor.
For thunderstorms in East Timor, distinguish Timor-Leste's mountain ridge, north coast and more exposed southern shores. These areas can have different moisture, temperatures and storm triggers on the same day.
Typical regional patterns, adapted to local geography. This is educational guidance, not a forecast for this year's seasons or a measured national lightning frequency.

March–May
Transition and local convection
Lighter or changing winds can allow sea breezes and daytime heating to organise showers. In East Timor, local thunderstorms can develop quickly even when the morning begins clear.
June–August
Different coasts, different weather
Seasonal wind reversal changes which shores and slopes receive moist air. Some parts of East Timor may be relatively dry while nearby islands remain wet; a countrywide storm percentage would hide these contrasts.
September–November
Another circulation change
Monsoon transitions and shifting convergence can support showers and thunder. For East Timor, compare local cloud development with larger incoming systems rather than assuming all storms arrive from one direction.
What to watch in East Timor

This country page combines the maritime southeast Asian regional pattern with local geography. Timing shifts between years, elevations, islands and opposite sides of mountains. Rainy seasons do not automatically mean thunderstorms every day. The calendar is a reading aid, not a risk scale.

What is heading towards East Timor?
Zoom out to include Indonesia, then follow the actual rain-band movement across successive frames. Borders do not stop weather systems. Use the map’s minus button to widen the view; plus brings you closer. A larger view gives context, not extra radar resolution.
- 01
Find the wider pattern
Zoom out until the approaching rain bands and nearby sea or land are visible. Check the timestamp and whether the frames are observations or model forecasts.
- 02
Follow several frames
Play the provider’s animation. Compare the same rain band over successive frames: is it approaching, weakening, growing or developing repeatedly over one area?
- 03
Check the airflow
Cloud-level winds help steer storms. The wind shown in the daily forecast is near the ground and can differ. Fronts, mountains and new cell development can change the direction.
- 04
Update your plans
Radar helps with the next short period. Use the 7-day outlook for broader planning and check local official warnings. A clear radar image does not prove lightning is absent.
This is a method for reading the map, not an automatic prediction of storm arrival. The country radar remains the opening view; Compare maps adds a draggable map.

Which view should you use?
The Rain radar tab explains that rainfall observations are unavailable here. Select Satellite for cloud imagery. These maps do not measure lightning strikes.
Check the area, not just the country name
The country view is a starting point. A large country or island territory may extend beyond the initial map. The country radar opens first. Choose Compare maps to add a second, draggable view alongside it (below it on smaller screens). Compare the timestamps and legends yourself; the maps are not synchronized and may share source data. Larger map expands the view. Missing data, especially away from radar stations, should not be interpreted as clear weather.

East Timor: warning levels
International severity terms
We have not confirmed a country-specific warning scale here. The terms below explain international CAP severity only when they appear in an official alert; they are not this country’s national colour codes.
Minor
Limited stated threat
The alert describes little or no known threat to life or property.
Moderate
Potential threat
A threat to life or property is possible.
Severe
Significant threat
The event poses a significant threat to life or property.
Extreme
Exceptional threat
An extraordinary threat to life or property is described.
Unknown
Severity unspecified
Severity has not been established. Unknown does not mean safe.
These terms do not confirm which system the local service uses. Read the issuing authority’s instructions, urgency, certainty, area and expiry time. Use the WMO directory to find official information.
