September weather, activities, events & insider tips
September Weather in Palawan
Is September Right for You?
Advantages
- Tail end of low season pricing - accommodations in El Nido and Coron typically run 30-40% below December-April rates, and you can still book island-hopping tours same-day or next-day without the March crowds when boats fill up a week ahead
- Water visibility is actually improving through September - the southwest monsoon is winding down, so you're looking at 15-20 m (49-66 ft) visibility for diving and snorkeling, compared to the murkier 8-12 m (26-39 ft) you'd get in July-August
- Firefly watching season hits its peak - the mangroves along the Iwahig River are absolutely alive with thousands of fireflies in September evenings, and the darker early evenings (around 6:30pm) make the displays more dramatic than the later sunsets in summer months
- Rice harvest season in central Palawan means the countryside around Puerto Princesa looks spectacular, the local markets are overflowing with fresh produce, and you'll catch harvest festivals in smaller barangays if you venture inland
Considerations
- Weather unpredictability is real - September sits right in that transition period where you might get three gorgeous days followed by a day of steady rain, making it tricky if you're on a tight 4-5 day itinerary and have specific tours you absolutely want to do
- Some island routes still get choppy seas - the tail end of habagat (southwest monsoon) means boat rides to Coron from El Nido or out to more exposed sites like Balabac can be rough, and operators will cancel if swells exceed 1.5 m (5 ft), which happens maybe 3-4 days per month in September
- It's genuinely humid - that 70% humidity combined with 29°C (84°F) highs means you're sweating through shirts by 10am, and if you're not used to tropical climates, the stickiness can be exhausting for full-day activities
Best Activities in September
Puerto Princesa Underground River tours
September is actually ideal for the Underground River because the lower tourist numbers mean you can book permits more easily - during peak season you need to secure permits 2-3 days ahead, but in September you can often get same-day or next-day slots. The cave itself stays the same temperature year-round at around 26°C (79°F), so weather outside doesn't matter much. The 45-minute paddle through the cave system is one of those rare activities where September's variable weather is completely irrelevant once you're inside.
El Nido island-hopping tours
The classic Tours A, B, C, and D are legitimately better in September than peak season for one simple reason - fewer boats crowding the lagoons. Big Lagoon and Small Lagoon in particular feel completely different when you're sharing them with 3-4 boats instead of 15-20. Water visibility is improving as the monsoon winds down, typically 12-18 m (39-59 ft) by late September. That said, you need flexibility - operators will cancel or reroute if seas are rough, which happens maybe 2-3 times in a typical September.
Coron wreck diving
September is when Coron's famous WWII wrecks start showing themselves properly again after the murkier monsoon months. Visibility climbs from August's 10-12 m (33-39 ft) to 15-20 m (49-66 ft) by late September, and the water temperature holds steady at 27-28°C (81-82°F). The Irako, Okikawa Maru, and Skeleton Wreck are all diveable in September conditions. Seas can still be choppy on windier days, but dive operators know which sites stay protected - they'll adjust the itinerary rather than cancel completely.
Firefly watching tours along Iwahig River
This is genuinely a September highlight that doesn't get enough attention. The firefly population peaks in September-October, and the mangroves along the Iwahig River south of Puerto Princesa light up with thousands of synchronized fireflies after dark. Tours run around 6:30-8pm when it's fully dark, and the 45-minute paddle through the mangroves is magical in a way that sounds cheesy but actually delivers. September's earlier sunsets compared to summer months mean you're not waiting until 8pm for darkness.
Port Barton island tours and beach time
Port Barton is what El Nido was 15 years ago - smaller scale, fewer tourists, and September is particularly quiet here. The island-hopping tours hit spots like German Island, Exotic Island, and Paradise Island with maybe 10-15 other tourists total, compared to El Nido's crowds. Water conditions are variable - you might get glassy calm mornings or slightly choppy afternoons, but the protected bay location means tours rarely cancel completely. The town itself has that sleepy beach village vibe that's increasingly rare in Palawan.
Kayaking and paddleboarding in protected bays
September's calmer mornings (before afternoon winds pick up around 1-2pm) are perfect for kayaking around El Nido's Bacuit Bay or exploring the mangrove channels near Sabang. The water is bathwater-warm at 28-29°C (82-84°F), and morning sessions from 7-11am typically avoid both the afternoon chop and the brief rain showers. You'll paddle past limestone cliffs, into hidden lagoons, and around small islands with minimal boat traffic. It's genuinely peaceful in ways the crowded peak season never allows.
September Events & Festivals
Harvest festivals in rural barangays
September is rice harvest season in central Palawan, and smaller communities around Puerto Princesa and the central highlands hold informal harvest celebrations. These aren't organized tourist events - they're actual community gatherings with shared meals, traditional music, and thanksgiving rituals. If you're exploring inland areas around Narra or Roxas, ask locals about any upcoming celebrations. It's a genuine window into rural Palawan life that you won't find in guidebooks.
