Which has better weather, Koh Samui or Mallorca?

Mallorca averages a higher weather score (75 vs 53). Weather is the biggest input to the score, but both have strong months and weak months; the month-by-month chart shows exactly when.

When is it cheapest to visit Koh Samui or Mallorca?

Koh Samui is cheapest in Oct–Nov; Mallorca is cheapest in Jan–Mar and Nov–Dec. Those are the low and shoulder months, when hotel rates and crowds ease — usually because the weather is less reliable, so check the month-by-month scores above before you book.

Can I visit both Koh Samui and Mallorca in one trip?
