I have a mat file that is a table with a lot of values for temperatures on each given day of each month of several years for different location. I need to extract from this file one location and the mean of each month. Everything I tried doesnt work.

Can you make a smaller table (i.e., less data but similar format), save that to a .mat file, and upload it?
For example, maybe just the first several rows of the table
t_new = t(1:10,:); % just the first 10 rows
save('table.mat','t_new');
(Maybe it's better to try to save the first 1000 or 100 rows instead of 10, depending on how stuff is arranged in the table.)
Alternatively, maybe a screen shot will be enough to figure it out.

basically that's the data I have (it continues further). I tried to do this to extract the data, bt it doesnt give much:
s =load('data_sectionM.mat') ;
year=SECTION_M(1,:);
month=SECTION_M(2,:);
day=SECTION_M(3,:);
temp=SECTION_M(67,:);
mydata=[year;month;day;temp];
newtable=table(year, month, day, temp)

If this is of datatype table, you might find the Access Data in Tables page helpful.
You describe selecting data using multiple criteria, and a desire to compute a summary stat based on those criteria. To me, that suggests using groupsummary. I find logical indexing works well for selecting rows to extract.
% Create a sample data set
date = datetime(2020,1,1):days(1):datetime('now');
date=date';
location = ones(size(date));
location(2:2:end)=2;
data=rand(size(date));
Tbl = table(date,location,data)

MATLAB Tables place variables in columns, so I would do something like this based on the code you have shared.
load('data_sectionM.mat') ;
SECTION_M = SECTION_M.';
long = SECTION_M(1,4:end);
lat = SECTION_M(2,4:end);
year=SECTION_M(4:end,1);
month=SECTION_M(4:end,1);
day=SECTION_M(4:end,3);
temp=SECTION_M(4:end,67);
date = datetime(year,month,day);
newtable=table(date, temp);
% Now with the data in a table, you can start analyzing your data.
mnTbl = groupsummary(newtable,"date","month","mean","temp")

It looks like, basically row 1 is year, row 2 is month, row 3 is day of month, and row 4 through the end are temperature data for various locations, and that the locations' longitude and latitude are given in columns 1 and 2.
Here's a smaller approximation of that matrix (with random temperatures every day for 2 years at 1 location):
SECTION_M = [ ...
NaN(1,3) 1975*ones(1,365) 1976*ones(1,366); ...
NaN(1,3) repelem(1:12,[31 28 31 30 31 30 31 31 30 31 30 31]) repelem(1:12,[31 29 31 30 31 30 31 31 30 31 30 31]); ...
NaN(1,3) 1:31 1:28 1:31 1:30 1:31 1:30 1:31 1:31 1:30 1:31 1:30 1:31 1:31 1:29 1:31 1:30 1:31 1:30 1:31 1:31 1:30 1:31 1:30 1:31; ...

Here's how you can get the average temperature for each month across all years (so 12 avg temps total, one per month) at a given location:
month_row = 2;
location_row = 4; % change this to the location you want, e.g., 67
monthly_avg_temp = groupsummary(SECTION_M(location_row,4:end).', SECTION_M(month_row,4:end).', @mean)
monthly_avg_temp = 12×1

Or, to get the average temperature for each month in each year (24 avg temps in this case - one per month for 2 years) at a given location:
year_row = 1;
month_row = 2;
location_row = 4; % change this to the location you want, e.g., 67
monthly_avg_temp = groupsummary(SECTION_M(location_row,4:end).', SECTION_M([year_row month_row],4:end).', @mean)
monthly_avg_temp = 24×1
