Tips for this trip
Pack light layers — even warm destinations cool off after sunset.
Check sun protection: SPF 30+, hat, sunglasses. Many of these cities sit closer to the equator and the UV index is high year-round.
Consider booking accommodation with air conditioning if you're visiting in the upper part of the temperature range.
