High Tide Warning for Bali Coasts, November 8 to 11, as the Rainy Season Arrives Late

Heads up if you’re near the beach over the next few days. Bali’s weather agency has warned of high tides and possible coastal flooding from Sunday, November 8, to Wednesday, November 11. The Bali high tide warning covers most of the southern coast, including coastal Badung and Denpasar, so Seminyak, Kuta, Canggu and Sanur are all inside it.

The basics: BMKG’s Region III office in Denpasar says the risk is linked to the new moon on Monday, November 9. The areas named are southern Jembrana, southern Tabanan, coastal Badung, Denpasar’s coastline, coastal Gianyar and southern Klungkung. No beach closures or swimming bans had been announced when the warning came out.

What BMKG Said

The warning came from Cahyo Nugroho, head of BMKG’s Region III office, on Friday, November 6, as reported by The Bali Times. The worry is what Indonesians call banjir rob, the tidal flooding you get when very high tides push sea water onto low-lying land by the coast. He also said it could disrupt loading and unloading at ports. ANTARA ran a BMKG high-tide warning for Bali the same day.

What It Could Mean on the Ground

This bit is our own reading, not BMKG’s. Tidal flooding tends to hit the strip right next to the sea: beach paths, low roads along the shore, and spots near river mouths. Beach clubs and restaurants on the sand may close off areas or move their seating back. If you’re walking or riding along the coast in the evening, watch out for water on the road, and keep children well back from the waterline when the tide’s in.

The Rainy Season Is Running Late

The tide warning comes while Bali is still waiting for the rains proper. BMKG Bali’s head, Aminudin Al Roniri, said on October 26 that rainfall still didn’t meet the criteria for the start of the rainy season, Bali Discovery reported on November 3. He expects central Bali to move into the rainy season between mid and late November, and the west, north, east and south of the island in December. BMKG thinks the season will be normal to above normal, and in the meantime it has warned about clean water shortages, land fires and sudden changes in the weather.

That’s a little different from what we reported on October 30. There, an ANTARA report from October 28 quoted BMKG’s Bali climatology station as expecting the rainy season to start across Bali in November. The two statements came two days apart and don’t quite match, so we’re giving you both rather than picking one. You can read the earlier one in our rainy season update.

Even before the season officially starts, the rain has been heavy in places. ANTARA reported a BMKG heavy-rain alert for November 2 to 4, and the landslide at a glamping resort in north Badung on November 1 followed 121 millimetres of rain in a single day. We wrote about that in our report on the Pelaga glamping landslide.

A Few Practical Tips

These are our suggestions. Check the tide times before you head to the beach, especially around the new moon on November 9. If you’ve booked a boat trip to Nusa Penida or Lembongan, ask the operator about conditions on the day, since the warning mentions ports. And when heavy rain is forecast, give yourself extra time on the roads, because low-lying streets can flood quickly. If you’re staying right by the beach, it’s also worth asking your host whether the property has had tidal flooding before.
