Mirissa whale watching — any trips getting cancelled this week due to weather?

Some operators cancelled yesterday and today because of rough seas. It's very weather-dependent right now. I'd contact your operator directly this evening — they'll know the forecast and whether they're running tomorrow. Some people are rebooking for later in the week when conditions look better. It's worth checking rather than showing up and finding out it's cancelled. The season is still good overall but this week has been inconsistent due to weather.
