A 96% chance means rain is expected over most of the area. Plan indoor alternatives. Around 0,5 in is forecast, which is enough to soak trails and slow traffic.
Wet roads are likely; braking distances roughly double in heavy rain.
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.
The gap between the warmest and coldest month averages 36°F - an unusually even climate through the year.
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
- High-factor sunscreen and a long-sleeve sun layer for midday
- Insect repellent and quick-dry fabrics for humidity
- Avoid unshaded sightseeing between 10am and 4pm - the UV index peaks at 8.
- If your dates are flexible, avoid May, June and July - historically the least comfortable months here.
