We missed the first weekly update of July, we found dolphins in all of the dolphin watching tours of the past 2 weeks.In the past week, we took half an hour or less to find the first dolphin group in 56% tours and only in 3 we didn’t found at least a second group.We sighted two dolphin species, the common dolphin and the bottlenose dolphin. We also had one sighting of blue shark and sun fish. We also had fin whales passing by the bay on the 14th, but didn’t managed to meet them as they were too far south.
On average, we had 8 guests per dolphin watching tour and 1 seasickness case. Sea state was on average sea state 2 and we got one day with underestimated forecast and got sea state 5, we managed to find dolphins with just some legs wet!
This following week we expect windy afternoons. We only will do tours in the morning, as finding dolphins in the afternoon would rely too much on luck.

The past week had an unprecedented amount of dolphins sighted in the river Tagus. A total of 5 sightings were recorded on video and shared throughout social media, 4 of them were in consecutive days. Last sighting of the week, the furthest upriver
All sightings were of small groups of common dolphins, corroborating the previous studies which indicated that common dolphins are the most sighted species in the Tagus. This contrasts with all the other rivers, which have mostly bottlenose dolphin sightings. This could be related to the depth preferences of these species, common dolphins prefer depths of at least 20m while bottlenose dolphins are perfectly comfortable in waters 2m deep. Most rivers do not get deeper than 10m, making them unsuitable for common dolphins to visit. However the impressive depth of the Tagus river with depths up to 60m, delivers enough depth for the common dolphins to visit while hunting schools of fish.
Only 2 of the sightings were in the usual area where we find them in our dolphin watching tours, close to the mouth of the river.
Two others were closer to the 25th of April bridge, one downriver and the other upriver from the bridge.
And on Sunday the last sighting was further upriver, inside the estuary, very close to the shore at Parque das Nações, the “New Lisbon” 25 km from the Sea. Impressive indeed but not close to a record, in 2010 this species were photographed 48 km upriver!!
The reasons why so many sightings condensed within a week remain unknown. Most likely numerous factors contributed to it, namely regular schools of fish entering the river probably for spawning, as feeding was the main activity seen in the videos.
