मुझे डेटाबेस के दृष्टिकोण से इसके लिए कोई सीधा समाधान नहीं दिख रहा है - आवेदन पक्ष पर स्वरूपण करने का सुझाव दूंगा, अन्यथा यह इस तरह लंगड़ा लग सकता है:

SELECT
   to_char(w1.w_Date,'MM/DD/YYYY'), to_char(w2.w_Date,'MM/DD/YYYY'), 
   to_char(w3.w_Date,'MM/DD/YYYY'), to_char(w4.w_Date,'MM/DD/YYYY')
FROM 
 (select * from weather where w_date = trunc(sysdate)) w1,
 (select * from weather where w_date = trunc(sysdate) + 1) w2,
 (select * from weather where w_date = trunc(sysdate) + 2) w3,
 (select * from weather where w_date = trunc(sysdate) + 3) w4
UNION ALL
SELECT
   w1.image,  w2.image, w3.image , w4.image
FROM 
 (select * from weather where w_date = trunc(sysdate)) w1,
 (select * from weather where w_date = trunc(sysdate) + 1) w2,
 (select * from weather where w_date = trunc(sysdate) + 2) w3,
 (select * from weather where w_date = trunc(sysdate) + 3) w4
UNION ALL
SELECT
   w1.w_type,  w2.w_type, w3.w_type , w4.w_type
FROM 
 (select * from weather where w_date = trunc(sysdate)) w1,
 (select * from weather where w_date = trunc(sysdate) + 1) w2,
 (select * from weather where w_date = trunc(sysdate) + 2) w3,
 (select * from weather where w_date = trunc(sysdate) + 3) w4
UNION ALL
SELECT
   to_char(w1.high),  to_char(w2.high), to_char(w3.high) , to_char(w4.high)
