Within 15 degrees of the equator, day length barely changes all year; seasons are defined by rain, not temperature.
Northern Hemisphere, so peak summer falls in June to August.

What to pack, what to skip
- Lightweight, light-coloured clothing and a refillable water bottle
- Sunglasses, a brimmed hat and SPF 30+
- A packable rain shell - 7 of the next 7 days carry a real chance of rain
- Insect repellent and quick-dry fabrics for humidity
- Avoid exposed ridgelines, small boats and rooftop viewpoints while gusts stay above 32 mph.
- If your dates are flexible, avoid May, June and July - historically the least comfortable months here.
