Com tide times

Com is a small coastal settlement on the northeastern coast of Timor-Leste, near the district capital of Lautem, approximately 200 kilometres east of Dili by road. The drive from Dili follows the northern coastal road, passing through the agricultural lowlands east of the capital, climbing through the central highlands, and descending to the coast at Baucau before continuing east along the shoreline. The journey takes 4 to 5 hours depending on road conditions; the coastal road is paved for most of its length but has sections that deteriorate in the wet season.

The reef systems off Com are on the outer edge of the Coral Triangle — the globally recognised zone of highest marine biodiversity, bounded roughly by the Philippines, the Moluccas, and eastern Papua New Guinea. Timor-Leste's north coast sits at the southern margin of this zone, and the reefs here have reef fish species counts comparable to those recorded in the Coral Triangle's interior. The reef off Com has not been systematically surveyed; visiting divers who have explored it report undisturbed coral communities on the outer slope in 8 to 30 metres, with fish diversity that rivals the better-documented reefs of the Dili area.

The tidal regime at Com is mixed semidiurnal, with a spring range of approximately 1.5 to 2.0 metres — the same tidal system as Dili, driven by the Indonesian throughflow and the Timor Sea's tidal dynamics. The Ombai Strait, which lies between Timor-Leste's eastern tip and the Indonesian island of Alor to the north, is one of the major throughflow passages; tidal currents in the strait proper can reach 2 to 3 knots at springs. Com is on the western approach to the Ombai Strait, and the regional current pattern influences local reef hydrography — the incoming tide from the Banda Sea brings clean, nutrient-rich water over the outer reef, driving the coral community growth.

The beach at Com is a quiet, undeveloped strip of white sand backed by coconut palms and the gardens of the small fishing community. Fishing boats are hauled above the high-tide line when not in use. The community makes its living primarily from fishing and from the small amount of through traffic on the coastal road. Basic accommodation and food are available through community homestays arranged locally.

Bird life in the lowland forest near Com includes the Timor blue flycatcher (Cyornis hyacinthinus), the buff-banded rail, and various parrot and pigeon species associated with the Lesser Sunda Island chain. The forest east of Com, toward Tutuala and the Nino Konis Santana National Park, is the most intact remaining lowland forest in Timor-Leste and has not been fully surveyed ornithologically. The national park coastal section has sandy beaches used by sea turtle nesting (leatherback, green, and hawksbill have all been recorded).

Visiting Com requires self-sufficiency: no dive operators are based here, no equipment rental is available, and accommodation is community homestay standard. The site is for independent travellers with their own dive or snorkel equipment who are comfortable with minimal infrastructure.

Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge.
