About...

World weather maps (world climate maps), aggregated into a (admittedly highly subjective) "travel suitability index", based on average monthly rainfall and average monthly temperatures. I use these maps to plan for future trips.

Data based on Wikipedia, with extracted monthly climate data for 2233 global locations. Downloadable raw data: [XLS]

 

Examples:

  • Bangkok [https://en.wikipedia.org/wiki/Bangkok#Climate] is  Horrible  for traveling in September, as it is  Very Rainy  with 334.3 mm (≥ 115 mm) of rainfall; note that temperatures are  Very Hot  given an average low temperature of 25.0°C (≥ 20°C).
  • Manaus [https://en.wikipedia.org/wiki/Manaus#Climate] is  Maybe  a suitable travel destination in September, as it is  Rainy  with 76.3 mm (≥ 65 mm) of rainfall; note that temperatures are  Very Hot  given an average low temperature of 23.7°C (≥ 20°C).
  • Maputo [https://en.wikipedia.org/wiki/Maputo#Climate], finally, is very  OK  to visit in September, as it is  Dry  with 3.2 mm (< 10 mm) of rainfall, and  Hot  temperatures given average low temperatures of 17.2°C (≥ 16°C) and average high temperatures of 26.1°C (≥ 25°C).
