I'll be in Pasikudah May 1-9 (in Trincomalee before that) and wanted to visit Ella and Nuwara Eliya from there, or between Trincomalee and Pasikudah. However, looking at weather forecasts from different sources shows rains or thunderstorms are likely just about every day.
What does that translate to in practice? Are those rains throughout the day, or for short periods? Are the hiking paths good or do they turn into mud?
If early May is already bad, is late April much better?
